Error code P0089

[Grishbok]

P0089 Fuel Pressure Regulator - Performance

This code is stored in my ecu and the cel is on. My question is, who else has taken their car in for this? My car only has 20k miles on it, so it better not be a cam issue.

[supamannn99]

if you get this code, that means you can get your cam checked.

The Audi Techical Service bulletin states that if this code pops up, you're entitled to having it checked and replaced it necessary. PM me your email if you want to see the pdf.

P0089 Fuel Pressure Regulator - Performance

This code is stored in my ecu and the cel is on. My question is, who else has taken their car in for this? My car only has 20k miles on it, so it better not be a cam issue.

I had that code. Took the car in to the dealer and they replaced the low fuel pressure sensor. No cam check though, as I was not having any performance issues. This was done at around 35k before the car was chipped and before I was aware that this cam follower problem could even occur.

[wayneB7]

Earlier this week (Wednesday) as Iput the car back into Stock mode, I got the CEL again so I drove instead to my mechanic who hooked up the code reader and sure enough -- P0089. He cleared it and as he did the first time around said I should watch it and if it comes back again, bring it to the dealer and since they fixed it the first time they will have to fix it again.

Like the first time this happened, the CEL returned after 24 hours, on the following day. I put the car back into APR93 mode and drove it with the CEL.

Today being my day off, Idecided to go to the dealer and see what he can do about it, so before even starting the car, I put the car back into Stock mode. Started the car -- no CEL. Happy WTF!

I still took it to the dealer and they claimed they could look into the history in the ECU and see what happened. I said fine, and that I would wait for it. Besides, they could also take that opportunity to fix my outside temperature sensor issue.

After about 2.5 hour they said the car was done (and it was also washed and 27-point inspected) and that they (a) replaced the outside temp sensor -- different issue, and (b) they 'recalibrated the ECU' so that this won't happen again. They never replaced the LP sensor again as far as I can tell. This is how the invoice read --

http://gwebworks.com/audi/LP%20CEL%20diagnosis%20-%20May%208,%202009.png

Any thoughts what they are getting at?

Good news is -- I put the car back into APR93 and still no CEL (just in case that triggered it last Wednesday and cleared it this morning!).

Warranty is up Monday, but I figure -- it was in their shop twice now for the same issue, they will have to keep fixing it if it keeps coming back. [wrench]

[Grishbok]

Yeah mine came on intermittently for a period of 3 days, and hasnt come back on since. Im not sure whats going on, but they wont touch the car until I can get it in stock mode, with the cel to the dealership and not have the cel turn itself off.

I cant be certain... but this seems to occur mostly on a full tank... we will see after tonight though. I will run the car hard and see what comes of it.

[wayneB7]

I cant be certain... but this seems to occur mostly on a full tank... we will see after tonight though. I will run the car hard and see what comes of it.

In my case the tank was down to 1/4 left. My mechanic suggested that it was not a good idea to let these cars get down much past half. While I trust what he says, I think that any manufacturer that makes a car that has issues with less than 1/2 or even less than 1/4 tank of gas does not deserve my money -- regardless of how nice the car is. My rule of thumb -- fill up at 1/4 tank.

[Grishbok]

I fill up at 1/4 tank as well.

Here is an update on this..

p0089 shows up after spirited driving.

CEL turns off after several drive cycles with no spirited driving.
CEL remains on in stock mode.

No performance issues and no real fuel cut to report, would just like to know why I can't go out and do a bout of Gymkhana without throwing a cel for the next 3 days.

Hmmmm ... Gymkhana, eh? Haven't heard that word in a long while, and certainly not in the US. [:)]

Define this spirited driving. How long / many miles did it last? Maybe I can try the same and see if I get the CEL.

When I got mine the first time, there was no spirited driving involved -- just my usual driving where the revs mainly stay below 2000 rpm all the while. The second time I got the CEL, I was not driving at all, but just switching to stock mode before leaving the office. Could be a coincidence, I guess, but I had driven it normally to the office that day.

[Grishbok]

hmmm... typically, it replicates after pushing the car into the 4.5k-6k rpm range, no fuel cut at 4.5. for maybe 2-3 minute runs. So pushing the car pretty hard in low gears, for 2-3minutes, upper power band.

It will also replicate on occasion after driving for maybe 20 mintues or so, and then doing a hard pull on the highway on ramp, or again pushing the car toward the upper power band.

Seeing as how it just kinda goes off, im wondering if the part is faulty or if this is just part of the design of the fueling system?

Okay I would have to find a good area to do this. My typical haunts are all full of traffic and at those revs I could get into trouble PDQ. Doing the hard pull after 20 minutes of regular driving should be easier to accomplish on my way to / from work.

I would hate to think that a CEL is part of any design of any car, let alone an Audi. Has to be a faulty part.

[wayneB7]

So today I go an fill the car up (was down to 1/4 tank) and after I put the cap back on, turned it through more than 360 degrees (just to be sure) started and drive off ... blasted CEL came back on.

There was no CEL before fill up and all was OK. Started the car and no CEL. Reset my Computer2 for mpg, mph and distance -- no CEL with car running. Pulled out of the gas station and onto the road, driving easy -- CEL comes on.

I am getting very tired of this. Have no clue what the code is this time but I would not be surprised if it was P0089. It is like I cannot trust this car to be code free. [mad]

I will just leave it alone for a few days and see if it goes off by itself .... again.

My wife wants a 2010 Prius .... we'll see how pissed off I get with this CEL until then.

[Grishbok]

Im trying to get the cel to appear when im in stock mode so I can get the dealer to replace the pump. Im leaning toward it being the fuel pump or a hiccup in the fueling system.

dear god dont get a prius, the amount of hazardous waste in those batteries is equivalent to 5 cars lifecycles. They arent a solution, they just dont let you see the damage to the environment they do.

[wayneB7]

Im trying to get the cel to appear when im in stock mode so I can get the dealer to replace the pump. Im leaning toward it being the fuel pump or a hiccup in the fueling system.

I am now out of warranty so the pump likely won't be replaced unless I pay. They already changed the LP regulator and that solved the problem for a couple months. I don't drive hard so I am baffled as to why it keeps doing this. If I was hacking the car all the time then I would probably lean towards it being the cam follower issue that many people talk about here. But the car drives fine.

Mine is in APR93 mode now, as it was this afternoon when I filled up. Maybe I should try changing modes and see if that clears it. it seemed to do it last time (2 weeks ago) because the CEL was there when I shut the car off for the night and then the next morning I changed mode to stock (before starting the car) and when it started up there was no CEL. That time it was P0089.

[Grishbok]

y'know, im just gonna call the dealership and ask the techs if they have had this error code and what the recomended fix is.

[wayneB7]

Please let us know what they say.

[Grishbok]

Im giving this ongoing issue a bump with some new knowledge


Diagnostic trouble code P0089 - The ECM commands the Bosch high-pressure fuel pump to deliver a specific fuel rail pressure - that can vary up to 23,000 psi depending on load and speed. The actual pressure is monitored via the fuel rail pressure sensor. If the fuel rail pressure varies more than desired or if commanded fuel pump flow is 100mm3/second or less, DTC P0089 will set.

Corrective action includes measuring the fuel rail pressure using a Tech II scan tool, then compare that to commanded fuel rail pressure with the engine running at 2000 rpm. The difference must be less than 20 Mpa.

A blockage in the fuel tank or plugged fuel filter could cause this fault (excessive vacuum in fuel line). If there is less than 5 in Hg of vacuum when measured at the fuel pressure test port at 3000 rpm, the fuel pressure regulator could be defective, and may need to be replaced. The fuel pressure regulator (FPR) is a sub assembly located on the Bosch high-pressure fuel pump.

My dealership will not replace a part unless the cel is on. So im about to wire that light up to a battery to make it stay the !@%$ on.

But it could be as simple as changing the fuel filter.

[Quattro]

thanks for that info =D

[tankdeer]

Bump. Any resolution to this? Just got this same code today. My first thought was maybe cam follower or diverter valve (which I ordered from ECS last week, and will replace anyways), but according to this thread it could be the pump (HP? Or low?) or the fuel filter?

Fuel filter would be nice, since it's cheap and was on my list of "preventive maintenance" anyways.

Thanks

[B72.0tsline]

my came on for only about 2-3 hours than it disappear ever since.

[viziers]

I was told by an Audi service person that that code means that the other pressure reg inside of the HPFP is what the problem is... I have the same code on my car now for 2 months...... I was also told that yes the HPFP does need to be replaced but was ok to drive that it wont cause any damage but being the light is on i wont know if something else goes wrong that may be damaging to the car....

Im just waiting until i can get an APR rebuild....

[Fast'n'Go]

With the p310b code he should have opened a technical assistant ticket on it but not a lot of places are doing this. His notes are semi right what they should say is he compared mvb 103 to mvb 106 and they were within range or compared them to an actual fuel guage. He probably didnt go any furthur into diag because it was a sporadic fault. Stop switching back and fourth from your flash and take it in next time it comes on, you wanna get that thing fixed before you go out of warrany. It could be the low pressure fuel pump or high pressure fuel pump and cam since its still coming back after they replaced the sensor.

[tankdeer]

Well I went ahead and ordered a fuel filter. Probably needed one anyways. I am going to replace that, diverter valve, and the cam follower (assuming the cam itself and HPFP are not toast) next weekend. I cleared the code yesterday and it hasn't come back on since. Car is running fine so we'll see what happens.

Not to dive into a seemingly dead thread but i just got this code (p0089) after WOT on an entrance ramp. i went to an auto parts store to get the code and cleared it. it said low pressure fuel regulator-performance. just wondering if any of you guys came to a conclusion about what it was? i hope to god its not my cam. i just replaced my follower about a month ago, and blew out my DV a couple weeks ago. im planning on ordering a new DV but what else should i take into consideration about this code? a fuel pressure regulator? fuel filter? any suggestions? i found on 034 that they sell a fuel pressure regulator for 50$. how easy is the install? any DIY tips?

[gtiedwards]

I posted about this last year. Same problems. My audi dealer wouldnt even look at the cam loab and fuel pump until I took the pump off, took pictures of the tip, follower and cam.

When I showed up at the dealer with the pictures they replaced everything and I have not had another light or problem since a year ago.

Good luck! [wrench]

[viziers]

It's the pressure sensor on the HPFP its the one that is on top of the pump it can't be changed unless you get a new pump from what i was told from an Audi service man in Florida. i have the same exact code for the last year..... I have a spare pump but that is going to be rebuilt w/APR internals.

When I got that code the dealer replaced the LP fule regulator and the problem was fixed.

Get it correctly diagnosed and get the part changed out. This is a common issue with these cars.

Doesn't that just mean they changed your fuel filter? I could be mistaken, but aren't they one unit?

[wayneB7]

Don't really know if they are integrated. The invoice said that it was actually the low fuel pressure sensor part# 06E-906-051-K. All I know is I did not pay for it and the problem went away.

[tankdeer]

Ah, sensor. Well that is a totally different word. ;)

I know the filter itself has SOME sort of pressure and/or flow regulator. Guess it's different though.

[viziers]

I have replaced my LP sensor as well and am still getting the poo89 code.... Thats when the service person told me its the other one on the HPFP. Atleast thats what ive been told!

Well its seems I ned to do some correction, As i have replaced the HPFP with the rebuilt APR HPFp and i'm still getting the P0089 code so my next step is to replace the furl filter to see if that will do the trick, after that i'm not sure what to check/do maybe take it to the dealer??

it also could be the high pressure thrust sensor. the low pressure thrust sensor gives P310B code. interestingly, I had that code and replaced the sensor. two weeks later the code came back. I cleared it and this morning it came back again! one thing I noticed that it always comes on when it is raining or it is damp and cool out. weird stuff... I am considering replacing my fuel filter next. if that does not help I might have to get a new fuel pump. after that, I am driving this car off the cliff Evel Knievel style...

oddly enough, my P310B code disappeared. went to work in the morning the CEL was on, came out this afternoon the CEL is off and the code is gone...

I should say that the same thing happened with my P0089 - it vanished. Keeping me on my toes I guess

it might sound scary, but I heard from a tech at AWE, that you should still get your cams checked, especially if you have a 2006 like me.

I also heard from people that your engine can fail, costing about almost 2 grand to fix or getting a new motor.

Remember guys, if you search for our complete motor, it cost around $6k. I always thought it would cost more, but it's still alot.

[plokm]

i got mine cam check

[diggs]

whats funnie is i have been going throught that problem for the past year.. my one friend (in audi) said it could be the intake flap or sumthing im not sure... ive changed filters better gas.. doesnt help. dearship said it was the pump....... let my buddy check it....... he said the pump is fine thats not it. dealership changed the low pressure sensor. like 3 times. still comes back on............ but few weeks ago i changed the cam follower........ check it it had some scraps on it.. but not really to bad 90k......... but i put the revised follower in . cam looked fine. since then... i havent had it come back on. lol idk...bulletin from audi stats that if its worn a fluxuation can come to the fuel rail p0089 p0088. so idk just sum food for thought

I and most other people on here have already changed the follower and still get this code intermittently.

I own a 2007 2.0T FSI A4.

About four months ago, I floored the accelerator on an open street, and my car went limp. It just got stuck in the 4000-4500 RPM. I took it to the dealer and they told me it had no error codes. It was also time for brake service which they did.

Sorry if I go back into a little history of my car.

The car was just 1 month over it's 3 year warranty and had 43,000 Km (28K Miles) in it.

After the service, a clicking sound that I was told was due to the low brakes just kept going. Then I began hearing like a scraping sound when releasing the accelerator.

After two weeks, they told me it that the clicking was due to a weared suspension support, and that the scraping noise was normal. No issues with the acceleration.

I talked to the dealership's owner and made a fuss about the turbo and suspension diagnostics.

The car went back in and now spent 2 months first to replace the Turbo´s DV Valve and Bypass valve, and then they told me that the computer showed a failure, didn't tell me which one but they also replaced the HPFP and the low Pressure and High Pressure fuel sensors (got a 20% discount). They continued working with the suspension until they told me that the only solution was to replace the support. I said no and went to pick up my car. They had adjusted the suspension and the clicking was reduced (they told me it was the engine's supports that made the noise).

When I started my car, the transmission indicator began flashing, the computer read low voltage error and they were going to dismiss it. I was not happy with that and decided to call Audi Customer Service. The transmission was checked again and a faulty command module was detected, I complained seriously at that and Audi made a warranty extension and covered the repair (a 4,500 USD cost). Then based on further discussions Audi absorbed 50% of the suspension support. This is why the car spent 2 months.

In total the car has spent 3.5 months of this year in the dealer.

Ok, now going back to P0089, yesterday while driving on the highway, the motor went limp again, and would not go over 4000 RPM's this lastes 5-10 seconds and then it just dissappeared, no CEL light turned off. I continued driving for 1.5 hours at high speed without any problems.

On the way back, the car repeated the issue first for a short stint (5-10 seconds) and then for a longer one that lasted at least 20 seconds before I could pull over, I was limited to 4,000-4,500 rpm, a limp engine (went from 70mph to 50mph on a moderate climb very fast). Once I stopped the car, the problem was gone. Again no CEL Light. I called the road support and they towed my car back to my home town.

Today in the morning, I went to the dealer and read the code in the computer, it was 0089.

Since the HPFP and the Fuel sensors have been replaced, there are only two alternatives from what I have read:
1. Replace the fuel filter.
2. Replace the Fuel pump cam.

If is the first option, no problem and I will not make a fuss, let's consider it regular maintenance.

If it is the latter, I will fight not to pay for this, so I have the following questions:
1. Since it seems to be a problem with the car design, will this be covered even if the warranty has ended.
2. Do you have to replace all the camshaft, or is the cam an independent one mounted on the camshaft?
3. Does anybody have any service document/bulletin that calls for this change?

Thanks for your help.

[viziers]

Well after a couple years of the P0089 code I finally got to replace my LPFP and so far I have not gotton the P0089 code back!!! Time will tell of course.......


UPDATE: Just checked for the code and the ****** came back that SOB! Back to the drawing board..

[Eduardo]

A Brief update:

I received a call from the dealership telling me that the camshaft had to be replaced, they would not give me a budget at that moment because they were sending the case to Audi. I had already contacted Audi due to the car failure.

I'm still waiting for an answer that should come back in a couple of days.

Does anybody have a copy or a link to the TSB's applicable for this cam failure?. I would like to have one in case I need to go back and discuss it with Audi.

Thanks in Advance

So I've been looking for a code 012555, when i should've been looking for P310B (I didn't read carefully enough through my scan report). So the chain of events that occurred about 1 month ago. CEL comes on right away after i start the car leaving work, I scan but don't clear the code. two days later the light goes off. Two weeks later the CEL comes back on, i scan again, and its the same code, i clear it thinking it had something to do with the gas station attendant not tightening the gas cap properly. A few days later, coincidentally, I changed my fuel filter only for maintenance reasons, not thinking this would help the CEL situtaion. But for those that this may help, The CEL and the code have no shown up since the fuel fitler change.

An update on my car:

The dealer told me that they would have to replace the HPFP, the gas pressure sensors, cam Follower and cam. This would total around 2,000 dollars.

I complained strongly to Audi Mexico, mostly since the Pump and sensors had been replaced 3 weeks earlier (less than 300 miles earlier). The car's warranty ended in December but the problem (fuel cut off) was already reported early January, not repaired, and when done they just replaced the HPFP without repalcing the follower (DUH!!).

Audi decided to repair the car free of charge (I had paid 550 dollars for the previous pump change no refund on that). Great support from Audi, but you have to raise the issue to Corporate level and have all your car history available. Was better for me since I own another Audi and have done all maintenance (except for tires) in the dealer.

Parts have been repalced with the latest revision, which Audi insists will avoid the problem's recurrance. (same parts as other 07 and 08 where there is no problem)

When they were going to deliver the car to me, they told me that the CEL was on due to a problem with the current/flow of the Low Pressure Fuel Pump, they have replaced the LPFP's control module but the problem persists, After a week I´m still waiting for the car.

I don't have the error code, but does someone have an idea what the problem could be?

Thanks

Anyone ever get a definitive answer to what the P0089 code relates to? On Saturday I changed my fuel filter, also checked my plugs (had gotten minor fuel cut a couple times). CEL came on, read as P0089, and had disappeared by the next day. Car is driving fine, I have only driven about 50 miles so far, and taken it pretty easy.

I know that I NEED to get on and check my cam follower, especially as I am at 82k and my CPO expires in February. But reading through here it sounds like people have replaced fuel filter, LPFP, HPFP etc and still get the code.

On mine, the dealer replaced fuel filter, LPFP, HPFP (includes the LP sensor), and ran the adaptation on block 103 (spoke with the tech).. Haven't had a problem since.

Old HPFP would give 107bar max
New one, doesn't drop below 112

Old LPFP 4.5 bar at idle, dropped to 1.5 under full boost
New LPFP 6.2 bar at idle, doesn't drop below 4.5 under full boost.

So I guess they were worn, but the car only has 60K km's.. Hope that helps you.

[Heratik]

I had that code. Took the car in to the dealer and they replaced the low fuel pressure sensor. No cam check though, as I was not having any performance issues. This was done at around 35k before the car was chipped and before I was aware that this cam follower problem could even occur.

After having my car in and out of the dealership for a month that's what they replaced on mine when I had that code.

Do you know if they did the calibration???? I never knew there was one for almost 2 years that I have delt with the P310B code.... Try the calibration if it has not been done yet.... It has to be done with the car idleing....

Vizi, which dealership to you go to?

I just had the P0089 code coming up yesterday, but in my case, the engine doesn't crank up unless it's cold (the engine, not the outside temp)

I had a HFC installed a month ago and last monday I had APR Stage 2 installed, not sure if it is related or not.

My car has 32k miles, but I'm afraid to go to the dealer and have my warranty voided because of the mods.

Any thoughts?

Thanks

I go to the one in Greensboro.. Good bunch of people there......


From the sounds of it, it might be your CAT as when its bad and it heats up it essentially expands and clogging itself where as when its cold it contracts letting some gas pass by..... Know what I mean..... At least thats what I was led to believe from years ago....

I drive to Greensboro whenever I need to go to the dealer too, Leith Audi in Raleigh sucks.

I'm gonna go to BFI tomorrow and have it check if it was related to the APR flash, but yeah, what you're saying makes sense.

I'm gonna check with 034 about the CAT as well, good thinking.

Thanks man

Ok, I'm at the dealer now. They replaced the low pressure fuel sensor (or something like that), but they didn't check the cam follower.

does anyome know the part number for the LP fuel regulator and where it is
i got this code yesterday on the rollingroad so until i get it fixed i cant get the custom tune finshed im getin fuel cut around 4500 5500
i know its not my HPFP cam or lobe all new
and for the min i dont wana change the lp fuel pump out till iv tried the lp fuel regulator
any help

Ugh, just came back from a drive with this CEL.

Log your LPFP Block 231 at a 3rd gear WOT pull to see what your values are, they should be no lower than 4.5 to 4 bar.... If that is fine then you might want to replace your thrust sensor on the HPFP... All in all it's going to be one of a couple things, either the thrust sensor on the HPFP, the HPFP, the LPFP or a short in the wiring....


P.S. In my case i'm almost 100% positive its a short in my wiring from when a shop pulled my motor and was a bit careless...

So, I just replaced my cam follower this past weekend, and did a pcv upgrade due to a vac leak. Took her for a spin today after clearing all codes and got the p0089. I checked for any leaks on the lines to the hpfp, I cannot find any, and the the lpf sensor seems to have some play in it (the black piece that connects to the metal thread) I am assuming that it is not supposed to twist at all when after close inspection it looks like it was sealed. I am going to drive around for a few days and see what happens. I have no performance issues with the vehicle at all everything runs very smooth and accelerates smoothly without fuel cuts. Any thoughts, I have been up and down these forums a few times today while at work. Also, when I removed the hpfp my lobes were not worn and the cam and piston looked fine, so I dont think the pump is failing, plus I had no issues before I replaced the cam follower with any fuel.

UPDATE: I forgot to add that I had a pcv issue, which I fixed while doing the cam follower. Today I am getting a new lpfs to replace the one in question. Hopefully my parts guy can get it by this afternoon, this morning I dove with wot, and still no fuel/performance issues. Will replace Fuel filter next if no luck.

*all brand new parts in car as follows*
Coil packs
maf sensor
pcv upgrade
spark plugs
cam follower
upgraded d stock dv

[CystmX]

Come to think of it. About two weeks before this code came up I had replaced my cam follower and added a catch can. Maybe my problem is the catch can. It was a sketchy install.

[jshutchins]

Come to think of it. About two weeks before this code came up I had replaced my cam follower and added a catch can. Maybe my problem is the catch can. It was a sketchy install.

I don't think the catch can is the issue, that is part of your PCV and vacuum system, p0089 Is related to fuel pressure monitoring. I'd look at you lpf sensor, and fuel filter. When installing the catch can you could have damaged the lfpsensor, the plastic piece is silicon sealed, and if there is an escape of pressure even minute that could be the issue. The seal on mine is busted as I may have twisted it to undo the clip :/.

Those are my current plan of actions, also did you replace the o ring on the fuel pump? I didn't and I am going to today as well, there are not any visible leaks, but even the slightest intolerance of air could set it off. I ll let everyone know how it all turns out once I get the parts on and clear the codes.

I didn't replace the O-ring. I bought it but didn't remember about it until everything was put back together. I didn't see or feel any leaks so I thought nothing of it.

[jshutchins]

Ok...so WTF?!?! I started my car before lunch, cleared the codes, and decided to rev and let idle to see if I could throw another code. Nothing happens purrs just fine and revvs just fine. I come inside to let the car warm up more. 20 minutes later I go outside and the car isnt running. WTF I think to myself. So I walk into our service dpt and tell them I think my hpfp just canned. We dont have any available techs to diagnose (nor anyone here that knows anything about audis except myself and I am not even a tech, I work at a dodge store) so I go back out to my car pull my tools out from the trunk because I roll with the tools needed to work on my car (its an Audi!) Take off the fuel pump in the parking lot, inspect it, inspect the lines, wires etc. Put the whole thing back together, crank the car for 20 - 25 seconds and POOF, she starts right up!!! Its been almost 30 minutes now and she is still idling away like nothing ever happened and what baffles me more is that the CEL is not lit up! WTF?!?! Who has thoughts because I am baffled by this hardcore![confused]

*Update* I got it to throw a CEL I was expecting p0089, but finally got a new one with no p0089 anywhere to be found p2539 this relates directly to the low pressure fuel sensor, will have a new one in the morning, will see what happens then.

Ok, so update, its been a few weeks. I replaced the low pressure fuel sensor the following morning after my post. Took me less than 5 minutes. I primed the pump, turned the key, and vrooooom! I let it idle for a few minutes, cleared the codes, and since I have not had any issues, other than a hard start every now and again (which is normal behavior previous to any issues I have had recently). No CEL, no fuel cut at idle. Car runs like a top. Now at 108k and growing strong! Put in a boost gauge that following weekend as well, now the car is really fun!

[a4b7]

How much is the low pressure fuel sensor? Im assuming it is easy if it only took 5 minutes. I brought it to the dealer and they told me it was my forge DV, so they took that out and put their rubber DV in, and changed my coilpacks (from recall). A couple days later, same code comes back..

[a4b7]

ok nvm disregard last post on how much it cost...I see the price posted in a couple threads earlier!

[naiku]

Reading this thread it sounds like people have got dealerships to look at their cam follower after getting the P0089 code, I have not had the code again, but last night on the way home from work was getting multiple fuel cuts. The problem is that with no CEL I am wondering if the dealership will even look into it.

I don't have the time, or the tools, to check the cam follower myself, and my CPO expires next month. I have been to the dealership before with fuel cuts, and they replaced the coil packs as part of the recall. Since I am still getting them, albeit very rarely, are they likely to look at the follower this time? or will they try to brush it off again as something else.

[Dangler]

i just tackled the cam follower and thrust sensor this past weekend. it isn't bad. the dealer told me they wouldn't check the cam follower unless i threw certain codes. (which i did around 38k miles and they replaced the cam, pump and follower) under warranty. They will probably not look at it unless your car meets criteria (whatever that is) needed to check the follower. it sucks i know, but changing the follower isn't bad, and you don't need any special tools, just read through the DIY's and look over your car. you'll need some extension triple square bits and some torx bits and a short stubby 17mm open end wrench.

and to depressurize the car, just let the car sit for 1 hour, and use the schrader valve to depressurize the system. you don't need to go through all the trouble of pulling a fuse to stall the car out and such, (unless you don't have the schrader valve.

[Bart-Man]

I have had everything replaced on my car. HFP, Sensor 5 times, fuel filter... and i still pop codes all the time.
I'm getting fed up with this issue. Cam was fine.

What should I do next, I have been dealing with this problem for 8 months. I'm getting tired of the dealer and their excuses.

[Dangler]

yeah after swapping all the parts i though would be attributed to it, I still get this code pop up from time to time. Can't think of what else it could be. All i care is that it doesn't pop up around the time i need to get inspected. and have it stay off after i clear the CEL, so that readiness is set....

got this code twice , comes on when starting my car , it take like 2-3 seconds to start sometimes n e thought>?

[scottns]

I've gotten this a couple times. I cleared it and swapped out the fuel filter. I doubt it had anything to do with it but I needed to do it anyways. Hasn't come back (knock on wood).

[80sGuy]

One day after the factory warranty expired, I got mine for the first time last week when my gas tank fell below 1/4 during the warning 'beep' mark. I later filled the tank and it disappeared. Yesterday, when the tank fell below 3/4 it came back on. I ordered the Thrust Sensor (aka Fuel Pressure Sensor) and hopefully that will solve the problem. I bought (not lease) the car new and so far it only has 24,600 miles on the odometer. I maintained it accordingly with AudiCare and don't mod my car, everything is bone-stock, not even tint! There is NO reason for me to fork out $$$ at such early time (besides having 14 payments left) considering the fact that I hardly even driven the thing. Just spent a fortune on New Tires and Alignment. Starting today, I will put aside $250/month in a separate account and serves it as a warranty policy. I will do this for 24 months, if I use it great, it not, even better!

[80sGuy]

I received the updated 'Thrust Sensor' today and replaced it myself, it took me a good 25 minutes because I didn't have the right tools and it was the very first time I've ever messed under the hood of my car (except for topping off oil). The old sensor was a 'J' model whereas the new one I put in was the updated 'K' version. The code had went off by itself for a few days before I swapped the part, but I immediately cleared the stored code right after the new sensor was put in. I then took it around the block in the afternoon and again for a longer drive in the evening, so far no code.

I'm not sure if it was my imagination but the car does feel 'tighter' in acceleration, the responses was much quicker when I hit the gas (in a standstill and on the freeway), in other words, less lagging and it felt like new again! Well, we'll see how it goes.

[clemsongt]

So I finally got ride of one CEL (for slight coolant leak), that I had for almost a year and almost immediately as if on cue, I got the P0089. My experience is that it will come on and by the time I crank my car up 4 or so times it will have gone away. It seems that the problem is not a recurring error, but sporadic.

My car is REVO tuned, but the REVO tune had been on the car for a year or more before teh P0089. I replaced the cam follower within 15,000 miles before the code. I replaced the fuel filter within 5000 miles before the code.

Who has ever successfully gotten the code to go away by replacing something? If you have, what did you replace?

[TFSI]

Its a mystery....
Mine is gone after replacing the n80 valve, fuel filter, pcv, o2 sensor.
Who knows it may come back?

[80sGuy]

Referring to post #101, haven't seen the code since. Knock on wood.

Bringing this thread back. Quick rundown.

- had cam/cam follower/hpfp/thrust sensor replaced
-went to stage 2+ running hofpupgrade's pump


Now I'm getting a P0088 and P2293 code. Getting this loud metallic rubbing noise when I'm on the accelerator pedal. Oil levels good. Car runs ok so far. Haven't driven it much yet but I will update after I put some miles on her. I don't mind the cel as it seems it's a common issue but the noise is pretty loud. Anyone have this issue when going to an upgraded hpfp?

Sorry to sound like a news since ive been on the boards a while but all the threads seem to hit a dead end as far as the noise is concerned.

[DRAKLORE]

Yes the noise "metallic chirp" has not been solved yet, prob some function or
Friction or extra strain caused by the upgraded hpfp. As that's pretty much the only common denominator...

[golfvdude]

I figured as much. I'm not getting any power above 3000 rpm. Only thing I can think of is either a boost leak or the timing is off.

[mario.barreiro]

Please forward pdf. This is the second time. 1st dealer changed Fuel Unit in tank low psi sensor in June 2011 ($780.00) Labor was $430.00 of that. They state they don't recognize the p0089 code or the 7E8 & 7Ec codes. They use a diffirent fault code reader. Now car is stallining again and wont start. Ran code with a MAC code reader and getting same code. Last time they said it wasnt the Cam follower.

Please help

[mario.barreiro]

Second time with code p0089. First time the dealer replaced low psi sensor and CN fuel unit. Worked for 5 months and here we go again. The problem I have is they don't accept or recognize the p0089 fault code. The dealer insists there codes are different becuase they use Audi fualt code software. Can anyone provide additional information. I hate to say it but I don't trust my dealer. I've got 80,000 miles on the car and I had 78,000 when they did the work.

Thanks for your help.

i wa told it was my fuel pump. 150 dollars later... and one week later. it came back....

Came back last night. :( So it went 3 months from the last time it was off. Started the car to come home from work and Pop! It's on. Car seems to be running fine. Try the trust sensor next I guess.

[Dangler]

Mine has come back on and off consistently since the temps have dropped down. once i gets down into the 40's. it comes on, but once back into the spring, and it's warmer...then no issues. the car runs strong and performance has not changed.

[80sGuy]

^^You should take it in since there's a warranty extended and it is mostly related to the (G410) Thrust Sensor or Fuel Rail.

[clemsongt]

So who has fixed this issue and it not been the thrust sensor (G410)?

It seems as though the P0089 either goes away if one replaces the sensor or it never goes away.


Has anyone who replaced the sensor and successfully eliminated the P0089 filed a reimbursement request and successfully been reimbursed?

[80sGuy]

I got the light back in Oct. 2011 and replaced the Thrust Sensor myself, hasn't seen the light since. Speaking of which I better fill out that reimbursement form.

[scottns]

I've replaced the thrust sensor and I'm still getting it. I got a scanner for Christmas so I've just been clearing the code and forgetting about it...

[clemsongt]

Replace fuel filter: check (5,000 miles before code)
Replace G410: check
Replace LPFP: check
Replace N80: check
Check HPFP: check (cleared by both me and Audi tech)

P0089 code: still there

Suggestions?

[80sGuy]

There's a 10/120 extended warranty on the stuffs mentioned from Audi for our B7s in case you haven't notice. P0089 seems to be a good reason for you to to bring it in and let them sort it out...assuming you have an '07 and later model.

I assume you are referring to the PCV and the G410 sensor. They have replaced both of them recently under that extended warranty/unannounced recall.

@hachu was this stamped on your filter? If not you may have gotten the wrong filter, 2.5L vw filters are only 4.5 bar and they are identical other than the pressure regulation. Also after repairs if you have vagcom it may be necessary to adapt the sensor (G410) to the system. Basic Setting 103 will run this adaptation

[DRAKLORE]

OE filters are 6bar

So I havent done the recall yet (though I'm out of warranty) and I have it scheduled for Friday. Of course today, I let the tank get kind of empty below 1/4 tank and the CEL comes on. Low and behold a P0089. No fuel cuts no matter which tune I run...hopefully the recall and a new fuel filter fixes it? F my B.

[schirm]

mine comes on once a week, and goes off the next day... usually comes on after WOT...I have to bring it in for the recall tho.

fuel filter pn 4F0201511E

[rnp614]

I just replaced the following:

Thrust sensor
PCV
Intake flap motor
N80
Fuel Filter

Code is still there, but I havent driven the car all that much. Will sit on a while and see whats up.

[hachuu]

replaced the LPFP and this looks to have fixed it.

[nepi]

So, is there any consensus on what fixes this problem? I've been to the dealer to get the PCV replaced because of the recall and the CEL came back on. I had the boost control valve replaced as well. When that was done, the p0089 code didn't come on for months. But after the PCV was replaced, it came on the next day. Usually comes on from cold starting the car, in the evening when I drive home from work the light is usually off.

Thanks

For those of you that had a laundry list and can't seem to tackle the issue, might as well check the MAF sensor to see if it's coated with dirt? Easy 2-screw on top of the airbox. Might as well clean the snow screen/filter at the very tip when you're at it.

[nepi]

So, there is no consensus on what solves this issue? What should I do to fix this problem?

[2006Scorpion]

I replaced my Fuel Filter and the code hasn't come back for almost a year (crosses fingers).

[groundround]

Do the N276 diagnostic in vagcom, if you hear it clicking away then it's good. But can go in and out when they are going bad.

[nepi]

Nice! Can you link me to that? Is this it? http://www.ecstuning.com/Audi-B7_A4-Quattro-2.0T/Search/Fuel_Filter/ES250315/ Is there a difference with the other fuel filters they sell?

How do I know if I should replace the fuel cam? Some people said they replaced this... I have close to 150k miles on my Audi A4. It is listed here: http://www.ecstuning.com/Audi-B7_A4-Quattro-2.0T/Search/Cam/ES252809/

What is the N276 diagnostic? Is there a way to do this without the vagcom? I have a regular code reader that was $20- not sure if I want to spend $350 for a vagcom...

[2006Scorpion]

Yes that's the right filter or you can do a little custom work like Drake did and upgrade to the GTI filter, also if you're at 150K on the original cam follower I would pull off your HPFP ASAP and check to see if your cam follower has a hole in it.

[nepi]

What does the GTI filter give you that that filter doesn't? I just placed an order with ecs for the Mann filter and cam follower. Anything else I should get?

Shit just noticed you are in Boston. I met up with Camoto, it's in one of the screens and you have your car in run position and it just activates it and will click rapidly. Mine made no noise and his clicked away.

Just went for a ride in his car and drives fine, the code is on and off no limp mode. Prob just a dirty fuel filter

[xamp]

had my car chipped to stage I and one month into it this code was thrown -__-. had my fuel filter swapped out and the code stayed away for about a week or so... then one day I was hopping onto the freeway and as I hit the gas to catch up with flow of traffic what do ya know... CEL shows up again. This is really annoying lol.

I have one question though, after I cleared the codes after the first CEL my car started misfiring like crazy ( #1 & 3) at idle. Turned my car off for 2 minutes or so.. turned it back on and no misfiring / codes whatsoever... anyone have an idea why that happened?

[schirm]

I have had this code for a while now It would turn on and off...turned out my cams were shot, cost me 2,000$ so get your cams checked/ follower ASAP if you have this code and you haven't found a solution yet. My car took a dump on me yesterday because of this code.

[nepi]

I replaced the cam follower, which the head was blown on, and the fuel filter. P0089 came on for one 10 minute ride and then went off a few days after these parts were replaced. Any ideas?

On a cold start (i.e. in the morning) the car takes an extra second or two to start. Could it be related?

Any ideas would be appreciated! My mechanic said the cam was replaced a few months ago, as was the HPFP.

Same exact thing with me. Would come on and off, the car started taking a couple extra seconds to start up when cold... Never went in limp mode at all... 2 months of this then she broke down, cams went fuel pump went LPFP went.

Hmm, the mechanic said the cam was replaced due to a recall? Perhaps he's mistaken (or I am). How much did the cam itself cost and how many hours of labor?

What's the LPFP? Is it expensive to replace? I've only heard of the HPFP.

How long has your car been okay for?


The mechanic checked the spark plugs and said they looked fine.

[nepi]

What is LPFP? I did a google search and a search on ecstuning with no luck...

[tankdeer]

low pressure fuel pump

[nepi]

That's what I thought, but when I searched for 'lpfp' nothing came up on ecstuning. Which one do you recommend? One is much cheaper than the other.. http://www.ecstuning.com/Audi-B7_A4-Quattro-2.0T/Search/Fuel_Pump/

How can I tell if the camshaft is bad? The camshaft is only $500, so why did it cost you $2000 to have it replaced? Does it take 15 hours to do or something?

Would you do the lpfp first, and see what happens? Or should I see if the camshaft is bad? I just need to know what to check for... as I said the follower was blown through.

cams went, the housing for the cam follower broke thats 500$ ...my HPFP snapped in half, so I had to get a new KMD internals, Low pressure fuel pump went, fuel pressure sensors were replaced, new Cam follower.. 760$ in labor needed tons of new gaskets.. and an oil change to get rid of all the stuff in oil.

[nepi]

Eek... how do I know if the cam is bad?

check the Cam follower...you have to remove the fuel pump, or have a shop do it.

[nepi]

I did and it was bad. I replaced the $50 follower.

Does that mean the camshaft is bad too? To replace that is like $500 just in parts? So a bad cam follower means a bad camshaft?

[schirm]

how bad was the follower

[tankdeer]

No, it means you should have inspected the cam while you were in there. It could mean the cam is bad, or the cam could be just fine. I hate to say it, but there are dozens, if not hundreds of threads with this information in it.

[nepi]

I just verified the cam was replaced 3 months ago. So I guess the thing to do now is replace the LPFP? Anything else to check?

Yes, lots of threads with no definitive answers and people saying they've had it for years. I don't want that to be me.

[schirm]

yeah from the cams being bad puts more stress of LPFP... they put my car together with new cams and everything, and was still getting the fuel cuts, replaced LPFP and all was good.

shouldnt your parts have been covered under the extended warranty? i just got the P0089 code today so im gonna take it in this week and have them replace the cam, follower, and HPFP. plus an oil change too.

[schirm]

Yeah but you need a mod friendly dealership..

[Dirtyylicous]

I have this code, has anyone with the code experience any shuddering while accelerating? Specifically at the 1700-2100 rpm range

I had the LPFP replaced last week and thus far, no codes! Car seems to drive a bit better too.

[TFSI]

UPDATE on my car.

I had the LPFP replaced while ago and got the first code since then, the same damn code P0089.
I've replaced the cam follower every 20k miles or so. Last one was replaced 13900 miles ago.

Any ideas??

[DRAKLORE]

Fuel filter

[TFSI]

Fuel filter was also replaced when I got the LPFP done...

[xamp]

im baffled by this code .... It has only popped up after I flashed my car Stage I. Changed multiple things, LPFP sensor, cam follower, fuel filter, etc. nothing has worked.... :(

[CoDRoX]

Guys, so I've searched the B7 forum but didn't find the information I was looking for, so here goes:

Can someone list all the parts that are covered in the extended warranty campaign? Or better yet, post a copy of the letter they received? I either didn't receive the letter or (, more likely,) accidentally threw it out.


I got the P0089 error on Sunday, so dropped off the car at the dealership today thinking that it was going to be covered under the warranty extension. Just got a call from the service advisor - they are replacing the fuel pump and fuel filter, but they are apparently not covered under the 10yr/120k warranty extension [headbang]. That, and a replacing a valve cover gasket to fix an oil leak around the engine bay, plus a whislting noise that wasn't there before.


They are charging me $1200+taxes (yeah!!!) but I didn't have an option but to suck it up and pay. My understanding from reading recent threads on this issue is that both should be covered under two separate warranty campaigns, so I'm planning to follow up with Audi of America for full (or partial) reimbursement.

Thanks in advance.

[tankdeer]

I haven't heard of any campaign that includes the fuel filter. As for the pump, if it's the low pressure pump then again, I haven't heard of anything including it. If it's the high pressure, it depends on the state of the cam/cam follower.

[nepi]

Jesus, that is a lot. I paid $350 for the LPFP, fuel filter and install.

The PCV (pressure control valve) is covered under the recall. That was the first thing the Audi dealer fixed when I got this code.

Thanks in advance.The warranty covers: Intake Manifold Runner Control Motor, Fuel Pressure Sensor, Crankcase Ventilator (PCV Valve). Why don't you tell them to hold off on the other non-covered items and replace the stuffs that are covered under warranty and see how that goes. $1,200 is way too much money. These are easy things to tackle on your own.
I fixed the Thrust Sensor/Fuel Pressure Sensor (G410) by myself when I got the dreaded P0089 back in Oct 2011 and hasn't seen the code since.

[golfvdude]

I had my cams, hpfp, lpfp, and cam follower 5k ago. just got it popped up again. Car runs fine. follower is good. It's an Audi thing....haha!

I know that's way too much monies but I was in a pinch and needed the car right away. When my original warranty expired, I set aside $3-5k for out-of-pocket maintenance work instead of buying a third-party extended warranty, so overall I'm hoping I'll still come out ahead.

[mbmcclam]

Anyone have any luck with AoA covering these out of the extended warranty. Ive been bugging my local dealer over the last year about cam and follower but the problem is Ive never once had the CEL come on. They wouldnt even look at it unless it does. Now im over the 120,000 which are all highway miles and now getting the P0089. I guess we will see, if not I will break it down myself but Audi should have recalled insted of extending especially with the knowledge of these issues. Maybe the purchase of my wifes new Q5 will help. Doubtful!!

[Buzzatron]

Bump on this thread!

Have this same code.

i noticed a miss around that same rpm range. Only when lugging the engine. WOT its fine. Also i noticed the shuddering goes away when operating temperature is reached.
[headbang]

Is audi doing a recall????? how long are you covered for?

Anyone have anything conclusive on this code? or has everyone got rid of their b7's by now???

love that quote about audi's being like strippers.

[clemsongt]

My problem is probably isolated to me, but it is another thing that you can check.

I had a P0089 code for a long time and eventually my fuel gauge went whack so I figured it must be in tank fuel pump (as the fuel sender is on that too). The supports on the fuel pump were bent. I replaced it and shortly after that my gauge was reading off again. I eventually figured out that I had a 4.0 bar filter on the car which I received as a replacement for the original as part of "routine maintenance". I do not know how I got the PNs mixed up but it was a perfect physical fit. Once I put the 6.0 bar on the car the code immediately went away, and once I straightened up my fuel pump, the gauge read correctly and has not gone back to reading incorrectly.

The reason it took me so long to figure it out is because I felt like there was no way my brand new filter could be the culprit. I also never realized it could have been the wrong part since it fit. So another thing you guys can check is the PN of the fuel filter (especially if you've changed yours). There should also be an imprinted "6.0 bar" on the filter not "4.0 bar" as mine had.

[schowe]

Thought I would add my input; I just checked my car for codes tonight and found 2 fault codes:


008801 - Boost Pressure Control Valve (N249): Mechanical Malfunction
P2261 - 008 - Implausible Signal - Intermittent
154 occurances

012555 - Low Pressure Fuel regulation: Fuel Pressure Outside Specification
P310B - 008 - Implausible Signal - Intermittent
2 occurances

The first one sounds like its the N75 that needs to be replaced but the second code has me a little worried. I bought the car back in May and the previous owner had no recollection of ever replacing the cam follower or any related parts (ie. HPFP, cams, etc.) Neither of these lights have tripped the MIL and they are soft codes, but I am hoping that the P310B (P0089) will be enough to get my dealer to inspect the cam follower. I am an 06 with 95k miles, have been feeling minor stuttering/hesitation at low RPMs and low throttle. Car also takes a while to crank over on cold starts occasionally (4+ cranks).

Hoping the dealer will at least inspect the cam follower, HPFP and cam, if not I have no problem inspecting it myself. Might do a fuel filter to be on the safe side too.

[jimrobbington]

Well, I'm joining this club too. Had my first p0089 pop up several months ago, and didn't think much of it, as we had just ran the adaptations and then did 2 hard 3rd gear pulls on the highway running logs. Cleared it immediately and hadn't seen it again since.

Anyway, second p0089 came on 2 days ago, when cold starting the car. Cleared the code tonight again.

I have already upgraded the lpfp about 700 miles ago, and I replaced the fuel filter maybe 10k miles ago. I will be checking my follower this week for peace of mind, but will also replace the thrust sensor. Will update.

Replaced my follower today. It's in great shape for ~40k miles of stage 2. Will replace the sensor next when I get one in.

Audi even changed the thrust sensor under the P310B RVU, to avail. As soon as I changed my HPFP with APRs, everything went away.

Damn P0089 came back on again today, not seen it for a while. Started my car at lunchtime, CEL on, driving fine, scanned it when I got home and sure enough P0089. It's been about 20k since I last checked my cam follower, so I will give that a check (most likely replace it while I am in there) and also put in a new fuel filter.

This has to be one of the most annoying codes though, no real solution for it except replacing parts and hoping!

Yep, I'm still getting mine. Have had it for about 2 months. I have cleared it multiple times, and it has gone away on its ow BBC a couple times, but it keeps coming back. The weird thing is that it only seems to come on during either start up or idling.

Lucky this thread is still up and running.
Let me first say that Audi of Silver Spring is awesome. They cleaned my car inside and out and changed out my cam follower and associated parts with no troubles at all.

Now the dreaded P0089 code popped up again. I know its not the cam because it was changed not even a week ago. The car runs fine with the fuel rail reading min of 700psi in the Torque app. The code was cleared last night but came back again tonight. Its weird that it only comes on right when I start it after work.
Any ideas on what I should look at? Should i disconnect the battery?

Also, the new HPFP looks completely different. It has an extra thread hole with no input.

Edit: So this is the pump that was put in http://www.ecstuning.com/Audi-B7_A4-Quattro-2.0T/Search/06f_127_025_K/ES1304269/
Where is the low pressure fuel sensor?

[Jhad]

The thrust sensor does not come with the pump. Most likely they just removed the sensor from your old pump and installed it on the new one (it happened to me). I would buy a new one. Here is the part number http://www.ecstuning.com/Audi-B7_A4-Quattro-2.0T/Engine/Fuel/Sensor/ES251666/

[pkny]

Thanks, jhad.
Do you think this is i am getting the dreaded P0089 code?

[naiku]

Does anyone else who gets this code notice the fuel pump priming longer when opening the drivers door? My code is off again, but something I had noticed was the priming behaviour changed before the code came on. When I leave for work today I will pay attention to see if it still primes longer, or is back to normal.

Edit: Stupid code came back on again, started the engine up fine, no code, looked down as backing out of the garage, CEL on again. I have not yet scanned it, but I am fairly sure its the same code. This morning my fuel pump did not prime when I opened the door, however I had opened it last night and it primed, but I did not drive anywhere. I did hear it prime while turning the key though.

[jimrobbington]

My p0089 cel only comes on during idle, or start up. I have never seen it come on while driving. It looks like this is common between us all on this page.

I have 145 bar prv, upgraded lpfp, swapped thrust sensor too. Will be swapping the hpfp soon to see if that changes anything.

[clemsongt]

I actually came here to ask if everyone else experienced their P0089 coming on at startup and guess that seems to be the case. Mine does not always come on at startup, but when it does come on it is on a startup or within 20 seconds of startup. It is always a cold startup, but not all cold startups. I have not figured out a pattern other than it is most frequent after work around 4-5 pm. It does not seem to be temperature related as it does it on 70+ degree days or 40 degree days.

Just to keep all my info in one place:
New G410, follower with 30k recently inspected, new LPFP, new fuel filter.

Most likely unrelated but potentially related as it is a fuel issue:
I do have some issues with the EVAP system - the fumes escape only back up through the neck causing the pump to shut off while fueling unless I have the nozzle slightly out and only the slowest pump setting.

[80sGuy]

I know some of you guys are having a ball chasing this P0089 code, but if checking/replacing stuffs like the G410 Thrust Sensor, Pressure Fuel Pump, etc., etc., still doesn't help....and since it is fuel-related; maybe it's about time to check out the Oxygen Sensors.

Care to elaborate as to how they could be the culprit? This is just me thinking out loud: If the O2 sensors were bad and the car running well, they would send the wrong voltage to the ECU which would then throw a code for too lean or too rich. If the air in the exhaust is too rich or lean and the sensors are bad but telling the car it is okay, then it would not send a code for too rich or lean (as I don't have and suspect others also do not have), but would mean something else is malfunctioning.

So I cannot determine how the O2 sensors are the culprit, either they are bad and it would come to light when the P0089 is fixed or I'm missing something?

[80sGuy]

^^Error codes are not specific to the 'problem' or culprit, but a start. Some (like me) tackled the issue by replacing only the G410 and never saw the code again, some have replaced something within the region, and a few others did something else. Like I mentioned, when all else fails, it doesn't hurt to check the O2 sensors, or maybe clean the MAF.

I understand they are where you start, but in diagnostics you start with an assumption and make logical conclusions from there. I started with "maybe O2 sensors are bad" and couldn't deduce why the P0089 would be caused by bad O2 sensors. I don't want to sound like a jerk, but if you can't tell me why they might be bad or present the symptoms we are experiencing (ie: P0089 code upon cold startup) then I have no choice but to ignore the advice. I'm not going to spend money on a blind hunt of replacing random parts.

Thanks

Good
... Add me to the list... :( Just threw P0089. CEL came on when WOT on the entrance ramp of the hwy. I've read through this thread and at this point am a bit confused on what is need to fix the issue. Current running APR stage 1 91 octane setting. No other mods.

G410 - 06E 906 051K?

Check Cam?

O2 Sensor?

Can anyone shed a bit more light on this?


Thanks in advance,

Also I have not checked the cam follower since owning the car (8K mile) currently at 76k. Probably a good idea I guess...

Bump anybody?

[GujuNilesh]

p0089 usually means cam follower. Get it replaced by the dealer. Its under warranty. I'm getting mine done right now. But they are taking forever to get it replaced. It's a good thing they let me borrow a top of the line a6 2013 model. lol.

p0089 usually means cam follower...Not necessarily.

I am out of warranty. Is this something that can be replaced under an open campaign for free? If not I would rather get a high quality follower and give my money to HPFP then the stealership. Please let me know.

with a p0089 code the stealer should check it- however, you may have to pay for the labor if it is not the culprit. The dealer should cover the repair up to 120k i believe, but usually will not replace until it is destroyed. It is very easy to check yourself- I recommend a diy to be certain. my 0089 code was not the cam follower.

Talked to the dealer a bit ago... They want $120 for a diagnostic. If it is the cam follower they wave the fee, if not I pay the $120 and it goes towards the repair needed....

Just erased the code and threw it back into stock mode before I left on my way home from work. Gonna see if it comes back up. If so I'll check the cam follower condition, but what other causes should I take into account? Any inexpensive things that can be replaced that may remedy if it does come back?

[Jhad]

The sensor on the pump can go bad- i forget the part number right now. I was getting p310b as well, so my hpfp and lpfp were bad.

[06AudiA42.0T]

I have a 2006 Audi A4 2.0T fsi.
Im at 124k miles (no warranty).
I keep getting the P0089 and P2293 codes.
Where should I start? I read through the thread and see people have replaced the fuel filter, High/Low Fuel pressure regulator(s), High/Low pressure Sensors,CamShaft....
The engine light goes on and off every few days. It usually drives perfect but I notice at high speeds it cuts out. Would this be my High or Low? Sorry for all of my questions Im still trying to piece this all together and any help would be appreciated. I am trying to sell my Audi but it would be a whole lot easier with that light off. I want an honest deal.

[Toxygene]

I got the same thing as the guy above me. I got the folowing codes after driving home after a meetup:

P0089 Fuel Pressure Regulator 1
P0089 Fuel Pressure Regulator 1
P2293 Fuel Pressure Regulator 2
P0087 Fuel Rail / System Pressure - Too Low

Conditions they occurred under:

Let the car warm up before I left a meet for about 20 minutes. Had some spirited driving while getting back on the freeway. While on the freeway, had to get off to make it to another freeway interchange. As I was getting back onto this other freeway I experienced some kind of fuel cut. Nothing happpened and I put the car in cruise for the next 20~30 min. Towards the end of the trip I took it out of cruise and had to maneuver around some moving obstacles and experienced the fuel cut even worse this time. Still no engine light. Gas tank light came on right as I was pulling into the station. Took it easy on the way home after filling up with gas but got the fuel cut so bad that the car lost speed while I was driving from about 75 down to 40. CEL came on. Limped home as the care seemed to loose a litte of it's punch. As soon as I got home I retrieved the codes and cleared them to see what the car would do. turned it on a few times and nothing seemed out of place. checked under the hood and everything looked fine.
This morning my wife take the car to work. No more than a block from our house the car dies on the street. She flags me down as I was leaving at the same time and I tell her about the fueling issues. She makes it to work but I can imagine the language in the car was not pretty.

As for what I have on the car

APR High Flow Pump
H2 Sport Cam Follower Fix

AEM Cold Air Intake
Black Forrest Industries Oil Catch Can
Brand New Spark Plugs
Coilpacks were supposedly replaced about 30k miles ago.

We are out of warranty but I'm wondering if the dealer would even fix it with the H2sport cam follower fix and the APR pump. I'm wondering if it's the thrust sensor or something bigger where I'd have to replace the whole pump. I only have the weekends to fix this, so if I could buy the part and replace it myself I'd do it. I've read through this thread but I don't see anything conclusive. Any ideas?

[80sGuy]

^^There's a campaign for the Thrust Sensor (G410) and most likely that's what it is.

[Toxygene]

Thank you. What kind of campaign are we talking about? Is this something I could simply take care of on my own? Seems simple enough to get to it. Is the part number listed in this thread. I'll do a search specifically for it.

[CleverA4Name]

Yeah does anybody have a campaign or recall bulletin on the thrust sensor?

[80sGuy]

It look something like this. Call your dealer.

[Toxygene]

I bought the thrust sensor and had a shop throw it on. They then drove it around for a day without any issue. Audi in Riverside said I might be able to be reimbursed for the part as it's covered under a TSB.


So far no codes. I'm going to go ripping around tonight to make sure.

I did the same on mine and got a reimbursement. Not easy though because AOA would need proof of the CEL on paper, and that the part was indeed installed for the reason.

I know this is an old thread and I have read it all but I'm having the same problem yet I can't find a solution and Audi isn't really working with me.

I bought the car in Feb. drove it from Washington to SoCal. In that process the driving down the CEL came on and ran a check with my Vag Com and got this code. I took it in a couple of days after getting back after finding out about the recalls. They said they didn't see any problems with the fuel system, cleared the codes and made me pay.... 2 months later, my car starts hiccuping when pressing the throttle, rough idle and delayed starts. Broke down a month later. Had a buddy help me and he got me a LPFP because the old one wasn't priming.

A few weeks later, the CEL came back on. I replaced the fuel Filter and did a full tune up(sparks, coils, oil, filters, fuel system cleaners, MAF...etc) and cleared the CEL. 250 miles later, the damn thing came back on. Well fast forward til now. Car was acting up for 2 weeks with very bad throttle response and very rough idle just to break down last week. Towed the car to Commonwealth Audi again after talking to AoA about a letter I have saying that the HPFP, Cam Follower, Cam Intake are under warranty and that I had a receipt from the previous owner stating that the Fuel Sensor was replaced before from the same code and if it came back again the HPFP needs to be replaced. Now I took it there and they say the LPFP is bad yet everything else in the fuel system is good. Car was priming perfectly fine it just wasn't getting fuel pumped into the engine. I don't understand. Now I have to fork over more money to pay for them to tell me again that nothing is wrong and they won't replace it.

Question is, wtf is making this code pop and why are the so adamant on saying the HPFP isn't bad at all? Paid over $300 just for them to keep telling me nothing useful.

[80sGuy]

^^Try cleaning the MAF. Two 'security torx bit' screws and located right behind the throttle tube. Check and see if the thing is caked up with dirt, if so spray clean it with MAF cleaner. Every option helps at the moment. And yeah, the P0089 code is a bitch. Luckily the revised 'K' version Thrust Sensor cured it for me.

[Unit1Evangelion]

I have the K version but that was changed out a year ago? I did change out the MAF recently... 3 weeks ago? Before I just kept cleaning the old one. When I changed it out, I tore apart the whole intake and wiped everything down.

[80sGuy]

^^edit: sorry, I went too fast and missed the maf cleaner part from your first paragraph.
What about the G410 Thrust Sensor??? This cleared the code for me!

[80sGuy]

Wow, well then.

[kaz02a4]

Sub'd to this thread too. Haven't gotten a MIL, but found stored codes P0087 and P2293. I've got a different thread here (http://www.audizine.com/forum/showthread.php/565532-Fuel-Rail-Pressure-Drop) about my specific case. I finally picked up a vag-com, so more data will be logged in the next week or two. A good stock prv is coming my way (thanks Jon!) so I'll have some more bits to work from.

It's shocking how many people have this issue, stock or tuned. It can't really be traced to one bad part either.

Looks like you are in the same spot I am. I have done everything you have and more. I've also removed the evap system from under the fuel tank in car that was causing restriction. I even upgraded the lpfp. I also upgraded the HPFP and am running stage 2+ software. Literally the only thing left is to replace the lpfp controller.

Do you only get the light to come on when you are at idle, typically just after starting the car?

[vce1232000]

I had this code come up and I had fuel psi cutoffs. The APR dealer that I had it at originally[wrench] did the KO4 swap couldn't find the problem. Moved to another APR-Audi dealer. They fixed[wrench] a few mechanical things the 1st APR dealer[poop] screwed[down] up. The only part they changed was the lpfp controller[up]. Bam. No more fuel cutoffs when[drive] and code gone[race]. [hail] to the APR-Audi dealer

[kaz02a4]

Eight. Eight emoticons. For a couple lines of text. I don't even...

Glad it was all sorted out though. These things seem awfully hit or miss. I can't wait to start diving into it.

Lol, welcome to the world of the mysterious P0089. I had the same experience with a local dealer, basically paid them to do nothing but read how long the lpfp was on for every cycle, total waste of money. They refused to even check my cam follower or any of the other possible culprits of the code like I specifically asked them to do. Don't even bother with the stealership, they'll just bend you over and give it to you raw with no lube.

It seems like there are just so many possible things that could cause this code you have to go through them one by one until you get lucky. My next step will probably be the lpfp some day, but I have absolutely zero performance issues from this code, maybe a rough start here and there but that's only on cold starts and after that it runs perfectly fine.


I had this code come up and I had fuel psi cutoffs. The APR dealer that I had it at originally....
God, seriously? You really had to put in a billion little smily faces? What are you, 5?
