- Unit was recently removed from a just crash damaged vehicle. This unit comes with a 30 day functionality warranty. new part list price from AUDI USA is $ 4,189.92 ***!!!RARE ECU ALERT!!!***   Even if you don't have a bad ECU, this is great to keep as a back up or for diagnostic purposes.  A faulty ECU is a common no start or random stalling problem with these cars. These can also cause issues with erroneous check engine lights, idle control problems as well as emission control & cold or hot start problems. Low power & lean running are also fair game. I have also seen fuel pump relay turn on faults (ECU won't turn on the fuel pump), as well as an condition where the high speed injector driver has failed. This causes the car to sit and idle fine, but it won't accelerate. Comes with a 30 day functionality guarantee- Please see the details related to this on the return policy details section of this listing. 

 

I have one of these cars as my personal car!  An extra ECU is GREAT to have for diagnostic purposes.
