1996 Audi A6 Quattro Q&A
1996 Audi A6 Quattro Question: Where is the engine computer?
I have a problem with a check engine light staying on. It was diagnosed as a problem in the computer, not a sensor which was replaced twice. I an looking into buying a engine computer from a junker, but could only find the ABS-EDS unit under the back seat. I need to check the part number. Where is it? Thanks! - DavidB
Is the repair shop that has told you the computer is bad an Audi dealership or independent Audi specialist? You may want a second opinion before replacing the computer. The engine control module and transmission control module are both in the passenger side foot well area. Its not as simple as just plugging in a new ECU it has to be reprogrammed on most modern cars. - patrick mannion
The computer is plug and play on this model. If the same fault code recurs it is very unlikely it is the computer. Be certain you understand the fault description and the conditions that cause it to be set. Thoughtful diagnosis and testing before replacing parts is the most economical path. Actually if you could tell us the exact code we could offer more help. - spyder
