Up for sale is a Working, in excellent condition 97 Audi A8 4.2L Automatic Model ECU. Removed from a recent crash damaged car that still ran.  May work with some others too. Audi part number listed at top, match this. As always your best bet is to match the part numbers with the part you need. Useful if you have had a failure or if you are getting a tuned unit and want to have a spare unit. This unit is over $2000 retail from a Bosch authorized service center.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.
