I replaced the battery in my '99 A4 about a month ago, and I messed up the radio code so the radio is locked for now. After I replaced the battery I had to go to the dealer to get the computer reset to get the car running again. Well, since the radio was locked, I tried to input it again, so I had to unplug the battery again. Well, the same thing happened, and the car wont run because the computer needs to be reset.. Is there a way to reset the computer yourself, or do i have to go to the dealer and spend $200+ to get it reset? This problem sucks and I dont want to waste even more money after this happened the first time.

 

If your engine is Drive By Wire, do a throttle body alignment.

 

throttle valve adaptation... only way i know to do it successfully is w/ the scan tool
