P2015 Code

[ajehoti]

Got my first check engine light today. It was a P2015 code Which states "Intake Manifold Runner Sen SW Ckt rng/perf B1.

Now how do I fix it.

Thanks

go to the dealership if you still have a warranty, but guessing by your mods, that's not a option.

Even with the mods the car is way out of warranty sadly. I'm going to tackle it myself. Need some info on fixing it and what is the culprit of the issue.

Sooo few things to check 1st the manifold flap position sensor is circled in red, make sure its plugged in and for some reason didnt become disconnected. Then in the back of the manifold in circled in green is actuator that controls the tumble flaps make sure that the arm is still connected right and isnt broken also note that it actually moves the flaps like it should...

Now Alex you have been the most helpful person I have seen on audizine. Thank you for your time. I will go check now. If this all checks out, what should be the next approach?

I had this same code last summer about 4 month after warranty expire. Audi try to get me to replace the intake manifold for $1600. It's either a stuck or broken flap. What I did was run half a bottle of sea foam in there clear the code and it haven't come back since. I know many people here frown on seafoam. I added seafoam to my list of maintenance once a year.

Took a look at everything and it all seems intact. The manifold from ecs is 142.53 which isn't bad since it includes the solenoid and sensor. I moved the arm back and forth and for sure there was no issue with it sticking. So more than likely there is a bad flap. I don't feel much difference performance wise. I'm annoyed of that check engine light. When I finally just got it all squared away too.

So I need a new manifold is the end case scenario huh?

More than likely, i had that code for like 2 weeks to only end up having the runner flap rod break. i would say your intake manifold is gunking up and is on it way out

[ajehoti]

Damn, looks like I got to get a new manifold in. Looks like a pain to do as well. Isn't IE releasing a manifold?

Ya they are suppose to be getting close to, but the thing is that it sounds like they are going the flapperless route so that would cause rough cold starting issues with an APR tune and would also cause some surging with boost, so unless they make a flappered manifold or provide a tuning solution probably not gonna be the best route for our car unfortunately lol... so it would just put you in the same boat your in now, dealing with that same code but actually feeling it performance wise.

And trust me on this on because when i replaced my manifold i tried running with out the head dividers and pulling the flaps out before i actually broke down and bought the new manifold and it ran like complete

Another thing i might just mention and i know your buddy or who ever told you that the ported head wont effect the APR tune, but those flaps control flow to the head, and a ported head is gonna flow way better than a non-ported head, the tuning could possibly cause this as well due to the ported head. Did you ever contact APR your self on this situation with running a ported head and their tuning? The only reason i mention this is because what i have just stated above above about removing the flappers and head dividers...

Hmm that is true, I did contact them and they told me they don't have time to tune my car because it is such a miniscule thing and it wouldn't be worth it to them (GREAT CUSTOMER SERVICE APR!! QUICK TO TAKE MONEY BUT CRAP IN RETURNING SERVICE TO CUSTOMERS!!) I didn't get any check engine light today which is odd. It might come back, although I was punching it all this morning and nothing came up. All in all though the car is good and really moves wonderful. Besides the dying bulb issue I have that it turns on then off after a few minutes and this intake manifold that went away (hopefully). That's really it.

I was researching the code on ALLDATA and it says the result of this is usually a bad map sensor. Is this true?

Never heard that before, i would say take it off and clean it, maybe dirty, but ive never heard of a map sensor throwing that code....

Neither have I, but inspecting the image of it. It has a green section inside of it which looks like it has something to do with the runners. Quite interesting.

[ajehoti]

And the code cake back f-ing wonderful

[Fburg A4]

where on alldata did you see that the MAP sensor might be the issue?

[ajehoti]

I would have to back to it in our service department. I will go later see if I can get a screenshot of it and post it. It states its a map sensor, if the map sensor isnt faulty after checking voltage then replace intake manifold. If still failing upon replacement of intake manifold then replace ECM. Alldata doesn't seem so useful at times.

[Fburg A4]

ok, i was looking at the p2015 code troubleshoot on alldatadiy, but in that section I don't recall it saying to check the MAP sensor. I'm assuming you are using alldatapro if you're at a dealership and you might have been looking at a different section of the site. just interesting to hear that the site said MAP sensor may be an issue for that code

[ajehoti]

Yeah it is strange it said that. I ordered a new intake manifold because the perfomance of the car is becoming sluggish at low end. It also isn't downshifting as well. Power wise the car sucks lol.

[My05S4]

A P02015 and 2025 code show up on my diagnostic. How can this be fixed without going to the dealership. Keep in mind that I just purchased this car back in January, "As Is". Am I pretty much screwed at this point?

Did you figure out your problem with the code? I am having exact same problem on my 2009 A4. I just got a check engine light couple days ago with the code of P2015. I looked at the Manifold why the car was running and noticed a "air leak" type of sound. At the back of the manifold I found an arm with a little plastic thing sticking out and was leaking a lot of air out of it. I pushed it back in into the manifold and the car rpm and even the sound started working batter. I drove it for a day thinking that fixed it but than realized that it popped out again causing an air leak. I did some brief research online and some are saying it is a Intake Manifold that is bad and needs to be replaced and some are saying that it is Intake Manifold Flap Motor (Throttle Body) that needs to be replaced. Any ideas or to put me into right direction I dont want to buy a part and not being it

Bump to an old thread. It might be common knowledge now, but ECS sells a piece that repairs or prevents the problem of the lever arm popping off. It's called the Intake Manifold Lever Arm Fix Kit. As my 2011 A4 just threw this code, I'll likely be looking into this soon...

[bb-tt]

There is an extended warranty on the intake for 10 years 120k miles I believe. Had my daughter's replaced last year on her 2010 cc with 80k miles

[Smac770]

Heh, just make your own.

The thin hammered out conduit strap was not sufficient so I backed it with a piece of lawn mower handle that had broken who knows when back, the end where it's flat and attaches to the deck.

Unfortunately, after I took my car in for maintenance at Audi, the very next day the CEL came on. I just recently got the VCDS and pulled the codes. I have the P2004, flaps stuck open, and the P2015.

The common fix is to buy a new manifold, which is not super expensive now... I think FCP and ECS sell the kit for about $580. But ECS has a part (Mfg Part #021071ECS01, ECS Part # ES#3195806) that fits over the lever actuator, which is $53. I don't know which way I should go. Has anyone used the ECS kit?

I did the carbon blaster cleaning about 10k miles ago, and the flaps seemed ok when I took the manifold off. So I don't think the flaps are broken. I can move the actuator by hand and it does not seem sticky, but for some reason it throws the code. Would like to hear from others what experiences you've had with fixes for this issue. thanks.

@GTinBR225 did you get it, did it work?

This was not available for the B8.5 about a year ago when I checked with ECS. Now they have one for the B8.5. Back then I was able to work the flap actuator by hand and get it loose, and it worked for long time, but recently the CEL came on again, one day after I took it to Audi for maintenance. The lever arm is not the issue on my A4, it is connected. But the P2004 indicates the flaps are stuck open. I'm not sure this would do anything for me. Thoughts?

[fordalols]

I'm pretty sure you can use the VW intake manifold for the transverse engine, it should save you a few hundred bucks as the whole kit is ~$260-270 on FCP/ECS
