I thought that maybe something is up with the N75 maybe? Really not sure. Gonna replace the temp sensor, and would the MAF have anything to do with it. I'm almost to the point of taking it to the dealership. I know they'd be on my *** about mods. What to do?

Default remove it, and spray with good electronics cleaner>>>

that you can get at radio shack....let it dry and then reinstall.....

How does the car feel??? is it running well, or is the power level inline with your boost level?

Default You Hit Limp Mode.....

Limp Mode will give you 5-8psi of boost and that's it. You will need to get the codes cleared via a Vag com. Same thing happened to me and the problem was fixed in about 5 minutes once the guys with the Vag com cleared my codes.
They don't clear even if you disconnect the battery. You need a Vag Com.

Default If in doubt replace the MAF.....

but first run a Vag com on the car.
I bet you hit limp mode and that needs to be cleared first.

Default funny thing is....he says 8psi, but does not say>>>

if the car FEELS that way....i would assume it does...but if the car is running strong..could be a bad gauge! FWIW....
