So sprayed it all out, tested it and well still just doesnt feel the same with boost. Still feels like its in limp mode. will drive friday and see if the engine light comes back on. If so ill just purchase a new MAF and hope that is the issue. Sucks living out in the middle of nowhere. Gotta wait till i drop if off at a Audi Dealer.

Something else to try... leave the MAF installed, but unplug it from the electrical harness. Start it up (it may start and die once) and drive and see if you get your boost back.

If you do, it is the MAF and needs to be replaced. The ECU holds default mixture codes, so it may work for a bit as stated if you reset the ECU, but when it starts reading codes from the sensors it will begin adjusting, and that's when you lose your boost.

You said you you bought it from an Audi dealer? Is it CPO (Audi Certified)? Too bad you live so far from the dealer... I live about 14 miles from mine and don't want to drive that far! (I need to get an immobilizer remote programmed with my car)
