Im missing something here i guess, replaced a burned out ecu with a brand new one from the dealer and it wont start at all. Had replaced clutch in it earlier and it had been on limp mode, then we bought a new ecu - now it wont start at all.

ideas? what to do, (i am a rookie with audis)

 

Take it to a dealer to get the ECU coded to the security system. The car currently thinks you are a thief.

Good luck,

Bob
