P0441 error and CEL?

[sandspeed]

I have had no engine issues, or real mechanical issues at all since buying my car two years ago with 64k miles on it. I'm up to 88k now, and the CEL came on this morning. Went to Autozone and had the codes pulled, and this is what came up:

P0441

The good news is that this is the only code that popped up. I baby this car with Royal Purple, and whatever the highest octane gas is that I can get wherever I am. It has a Stratmosphere intake and Thermal catback, but no other engine mods. I have had no issues, misfires, or other noticeable engine problems. So does anyone have any idea what happened?

Evaporative Emission Control System Incorrect Purge Flow - that's what the code means.

Check your suction jet pump (do a quick search and you'll find the location) to make sure it isn't cracked or coming apart.

Also, do a leak test. You have a leak somewhere around the suction jet pump that's not sending the needed amount of vacuum to the evap purge valve.

Should be a pretty easy fix...once you find the problem that is.

Here you go:

The first pic will help you see where the suction jet pump is.

The second pic is the suction jet pump. It usually cracks or begins separating on the left side (the larger side of the suction jet pump).

Hope this helps!

And this is the same on a 3.0?

[Dan1969]

So apparently this system is what stops the unburnt fumes from going into the atmosphere. If the above recommendation doesn't work I would clean the MAF. Oh yah, I don't think the location of these hoses is the same as the 1.8T. Also something tells me that your gas cap has something to do with this...

Here is someone that had a similar problem. http://www.audizine.com/forum/showth...ect+purge+flow

Yeah, didn't realize you had a 3.0. Next time, make sure you post that up.

It's probably different and that's out of my league...sorry.

Or I could have read it underneath your avatar...my bad...

shit but you helped me alot
i keep getting thesame code over and over
i also have a question
i have a BOV, could that be a problem too?

[Valve_Cover]

BOV isnt the problem , def a evap issue. If the code comes back quickly every time you erase it that means you have quite a big leak in the system. You need to check for leaks (nitrogen smoke machine works best). If you don't have access to one then unplug your purge solenoid on the tank side, not engine side, and blow compressed air into the hose ( very low pressure i.e. less than 15psi.) You will hear a hissing noise where the leak is

NOTE: you will also hear a hissing noise at the far end of the car where the vent solenoid is located, this is normal since it is in open mode while the car is turned off. If at all possible use VAG-COM or any generic scan tool to shut the vent solenoid which will help greatly in finding the leak;

Hope this helps!

my pleasure! let me know if you need any more help

did the leak test today found shit load of leaks
main thing was the FMIC sensor and the piping
now i have to change the injector seals and change the oil return line cause it leaks alot of oil

Was it leaking oil before you did the test?

Did you remove your oil cap and plug off the PCV return hose before starting the test?

[Vince Stark]

yeah it was leaking before
and i did remove the cap

Did you plug the PVC return hose?

[Vince Stark]

no i actually neglected that and ended up with a smoke screen but after 3m of driving it went away.

I have gotten the same code. I am actually in the process of getting that fixed. You need to either, replace your N80 purge valve OR/AND replace your gas cap...

The N80 Purge Valve is right about the airbox and it makes a definite "ticking" noise when it is working. replacement can be found online for about 80 dollars from www.purems.com

Be careful...it's easy to mess your seals up. Putting the crankcase under pressure is a horrible idea. But it's okay...now you know.

I thought the oil started leaking as a result of the test, because you didn't plug the return hose, but that's not the case.

yeah man, audis are very complecated cars even a slight mistake can cost you alot of money.

fuck me twice the code came back again
i went a whole day without it and today i went over a bump and it came on

I'm assuming you fixed ALL the leaks you found?

[Vince Stark]

thats the thing. i did.

Did you simplify the evap/vacuum system at all? Or is everything still stock?

[Vince Stark]

Well, I'm afraid you didn't fix all the leaks then. I know this isn't what you want to hear, but do another leak test, MAKE SURE there are no more leaks and let us know what happens.

The only reason why you are getting the code is because there is not enough vacuum present when the purge valve opens. The only reason why you aren't getting enough vacuum is because there's a leak somewhere...

Sorry buddy, I don't know what else to tell you. Oldguy or diagnosticator may step in soon and have a theory that's beyond me...but I do know the reason why you are getting the code.

Maybe post up a pic of your purge valve and your suction jet pump. Something's wrong in that whole tangle of vacuum lines...

Good luck!

Thanks dude
ill try to get some pics up
and ill do the test tomorrow and let you know what happens
btw do injector seals have any impact on the leak issue?

Can't help you there...sorry. Just make sure to plug the PCV return hose and take off your oil cap.

That i will do

did another test
no leaks anywhere dont know what to do
got another code though
P0411
secondary air
injection system
incorrect flow

Something is definitely going on with your suction jet pump. All of the systems you have been getting codes for, are in some way or another, attached to the suction jet pump.

Here's what you should do: Remove every check valve, and the suction jet pump, and check for functionality. Make sure they are all working properly, I'll bet one of them isn't.

How many pounds did you pressurize your system to successfully?

You might need to do one more leak test. Pour soapy water on every check valve, including the suction jet pump, and look for bubbles.

I'm really thinking it's the suction jet pump on this one...

[Vince Stark]

i sprayd windex on everything including the suction pipe and the only bubles i saw were next to the fuckn injector seals
the max i put was 15 psi

Okay, so you don't have leaks then.

I would remove those plastic pieces and check for proper function.

i just spoke to the previous owner and he told me that he used the sock seals with the new injectors so im going to buy the new ones tomrw
what plastic pieces are you talking about?

Suction jet pump, check valves, T splittings, ect.

They might not be leaking, but if a check valve is bad, then it's possible your evap purge valve is getting a boost signal. If it gets a boost signal, it'll throw a code.

If ANY of the plastic pieces involve with that system are not functioning properly (take em all out and test em) it will affect everything else.

[[email protected]]

Actually, I'm betting that's your problem...

Hence why you've gotten evap and SAI codes...one of the PLASTIC pieces is bad.

I failed emissions a couple weeks ago with a P0411. Can you tell me what this plastic peice that looks like its broken is and what it does. I noticed this part being in one of the pictures above. I have a funny suspicion that this is caused the CEL. Another this i noticed is that it starts to tick for about 60 seconds and stops.

That's a one-way check valve, that restricts boost signals from reaching your EVAP purge valve. You received that code for incorrect flow. There's a good change it's causing your CEL.

[bmags88]

Thats the best news I've heard since it failed. And the ticking? I'm assuming that there should be a part # on this? I wonder how much it costs.

Off the subject...Loving the gauge!! I had a Autometer before and this one blows it right out of the water!
