Sup guys, alright im pretty pissed about this engine light LoL..Anyways what happen was I went for an oil change today that took an hour and a half for some reason after that was done got in my car started it up and engine was on. So i went back into the shop and told them my engine was on they took the car in to scan....1st scan they said it was something along my air intake cause i have an aftermarket AEM DryFlow filter in. 2nd scan they said its my throttle body flap does anyone know better ?? Help plz thnx

oooh btw they deleted the engine light but popped back up when i drove off.

Well whats the code?

**your daddy** · 10-01-2010 07:39 PM

sounds like they started the car with the oil cap off. most likely has similar faults as a faulty pcv..

no idea all he said was the first scan showed mfa sensor cause of my air filter,then second scan he said that went away and its telling something about the throttle body flap ??

just have them erase the code and see if it comes back in a few days. Aftermarket air intakes usually dont throw maf codes and intake flap motor (if thats what your referring to) is a known problem and is a relatively easy fix. But best you can do is see if the code comes back.

well they deleted the code came back on when i left the shop but this morning when i was going to work it went off and still never came back on...but yeah im referring to the intake flap motor he told me thats a common problem

Probably it will come back, and probably has nothing to do with the oil change. There are hundreds of stories of "just had my oil changed, then......". In my experience it's about 50/50, shops fault/bad luck. If your not sure, get a second opinion at another shop. IMHO, most techs love pointing out other shops mistakes, for good or bad.

Yeah im prob going to do that just dont feeel to good driving with an engine light on even tho he told me its nothing serious in this case.

Take it to autozone and get the code. I know the light isnt on, but the code will still be stored in the ecm. Could be simple as an evap leak.

Evap leak ??

this is normal if they started the car without the cap off. Happened to me once or twice :( Clear the codes and drive for a couple of hours. They code may never come back which was the case with me.

**STONER** · 10-03-2010 08:17 PM

Yes,

Maybe an evap leak due to gas cap or n80 valve sporadically not performing to oem design. Or perhaps a system to lean fault which could be caused by the oil cap, crankcase valve, etc. The list goes on buddy. Just get me the code and I will tell you all.

**AudiiB6** · 10-04-2010 01:53 PM

alright thnx man ill get you the cope asap,what computer doe sthe b7 use "obd2 scanner ??"
