Explain This One...

[BrewDude]

2013 allroad.

Pulled out of the driveway to pick up the dog from the vet, immediately get an ASC and TPMS fault. Pull into the vet's office parking lot, cycled the ignition, fault still remained.

Got the dog, started the car again and drove for a bit, ASC and TPMS fauls disappear. CEL pops up.

I did do a VCDS scan before anyone says anything...all the pertinent modules that came up with codes are listed. Car was just in two weeks ago for 45k service which included the PCV recall and two days ago for the cellular module to be replaced (stuck in 2G with known 3G coverage areas)

[itlnstallion818]

what mods do you have?

[BrewDude]

Hi flow cat with spacer
GFB DV spacer
3.0T intercooler
KW Height Adjustable Springs

Essentially nothing that would trigger the ASC/TPMS/CEL all at once. ECU has not been chipped.

This part stands out to me because this code has been stored 20 times where as the rest have only happened once. Have you tried removing your GFB DV spacer?

[van462]

Is the car running on limp mode currently. I'd make sure the MAF was connected and the wiring going to it look good. Also look over air charge lines from turbo to intake. If a hose is off at idle it won't really show up. But off idle the air will be sticker in the opening vs thru the MAF. ECU won't know know about the unmetered air and not add fuel (lean). The primary O2 sensors detects massive lean event and triggers limp mode to disable boost pressure to preserve engine. Reduced ECU ( limp) sometimes causes the Christmas tree effect of many faults that aren't really there like parking brake, tpms.

[auditd0rk]

Is the car in limp mode? If so, check your intercooler pipes, too. When one of those puppies pops off, the whole dash lights up like a Christmas tree.

EDIT: What van462 said :)

[itlnstallion818]

when i had issues with my MAF sensor, it tripped my TPMS, CEL and traction control-- apparently it was all on the same circruit? i'd look in to that

[van462]

Also the P2261 is a soft code that doesn't trigger a CEL. It's fairly common with the GFB DV. http://www.audizine.com/forum/showth...-Bits-DV/page4 post 123

[BrewDude]

So I cleared the codes and...nothing so far. Car was not in limp mode when everything happened.

I'm going to consider it a computer glitch but I'll keep an eye on it since I've got to drive the car 60 miles round trip to work on an 8-day shift. I just hope it doesn't crap out on me in the middle of the night on the drive...

[A4 Centaur]

^ Mine went bonkers with the MAF going bad.

[Lambda13]

I may have an extra MAF. lol

[AllroadCorbin]

If your MAF is loose or not connected then you'll oddly get a TPMS CEL on your dash. I forgot to plug mine in when I installed my intake and got a zillion codes like this. I also have the P2261 soft code for the GFB DV+ but as another said... it doesn't really mean anything or matter

When mine went I got parking brake and traction control. No TPMS for me.

Thing is though, there shouldn't have been any reason for the techs to be effing around under the hood for a PCV recall.

I'll have to pop the hood and check. BTW still no issues since I cleared codes.

Replacing the PCV involves removing the cam valve timing clips and coil pack harness which the MAF plug and O2 sensor is routed through. It's impossible to change out without 'effing around under the hood'.

Not saying this is your problem, but it's not outside the realm of possibility that the MAF plug could have become disconnected or wiggled loose when doing this service.

Considering this is my DD, I don't poke around underneath the hood much and have limited the mods to keep in the good graces of Audi.

If I want to tinker, I've got the 450hp beast nestled in the garage next door. :D
