HELP!! Please.... New To An Audi
I just bought an 2007 Audi A4 w/2.0T engine. Everything is stock. It has 52000 miles on it. The check engine light came on last week and turned itself off the very next day. But it turned back on again the day before yesterday and didn't go off since. I bought a OBD scanner and pulled off 3 codes. They are "P0642","P0299" and "P2004". I know the definitions of these codes, but have no idea what the causes are. Can anyone happen to experience the same problem help me out? Let me know what the problems are and how to fix them? I don't want to head to the shop without having any idea and get ripped off.
Appreciate any response.

"P0642" - Sensor Reference Voltage “A” Circuit Low
"P0299" - Turbo/Super Charger Underboost
"P2004" - Reductant Temperature Sensor Circuit Low Input
Sounds like in reality it could be a something as simple as a boost leak. I would check your hoses and see if you have anything loose. Has the car been lacking power?
