I have a 2002 audi tt 1.8L turbo. My problem is all the electronics reset overnight. The radio, the clock, the high performance chip, ECU, etc. How does this even happen? none of the electronics are new. I did however get a new turbo for it about three weeks ago. The dealership did not have a stock replacement turbo so they installed a stock 2006 tt turbo. Could this have messed something up?

 

not likely, and things dont just "reset"... you shouldnt lose the chip either, that just doesnt make sense... contact who you got the chip from and ask...

hopefully you have the radio code to reset that.. and the clock is easy, just fiddle around with the bottons by it. (i think pull the left and twist the right?)
