s4dreamer Posted March 17, 2003 Report Share Posted March 17, 2003 Can someone tell me where I might find the number of the ECU in my (2001) A4 Quote Link to comment Share on other sites More sharing options...
Drillslinger Posted March 17, 2003 Report Share Posted March 17, 2003 ON the ECU itself Or if you have a print-out of a VAG Com diagnostic, it should show it there as well Quote Link to comment Share on other sites More sharing options...
gambba Posted March 17, 2003 Report Share Posted March 17, 2003 There's a white Bosch label on the ECU as far as I know which details the Bosch and Audi part number. And from what I can make out on the Etka parts CD is that your ECU should be 8D0 907 401 and ending with either N,L or M dependent on options, I may have this wrong but I based it on the AFB engine model/serial number prefix.

Dave Posted March 17, 2003 Report Share Posted March 17, 2003 Isn't the number on the inside of the manual on the printout? Dave Quote Link to comment Share on other sites More sharing options...
Gaunty Posted March 17, 2003 Report Share Posted March 17, 2003 What do you need that for Trev? Thinking of getting the old girl chipped? Is that because you couldn't keep up with me the other night? Quote Link to comment Share on other sites More sharing options...

s4dreamer Posted March 17, 2003 Author Report Share Posted March 17, 2003 Well, I thought the ECU was in the rear left of the engine compartment as you're facing the front of the car, but if it is where I think it is, there are no external labels on it and you need a torx driver to get the lid off. There was something else nearby with an Audi part number on it: 8E0 612 105H Looked a bit of an odd shape for an ECU (I imagined a rectangular box, but this is kind of egg-shaped), so I doubt that't the thing really. Checked the service manual and the ECU is not listed on the sticker - only the VIN, engine code, external & internal option codes and paint code.

I contacted Revo and they said they don't have the code complete yet for my engine, but wanted to know the ECU number so they can check. TBH, I don't think the missus will permit me to spend the money, but there's no harm in doing the research is there Quote Link to comment Share on other sites More sharing options...
Drillslinger Posted March 17, 2003 Report Share Posted March 17, 2003 Not sure on the S4 Dude, but I know on my A3 it's up under the wipers. Like I said though, any diagnostic printout should have it Quote Link to comment Share on other sites More sharing options...
fatcat Posted March 18, 2003 Report Share Posted March 18, 2003 This might sound bleedin' obvious, but take it into your local friendly Audi dealer and ask them to retreive it via the vag.com. Chat the bird up in reception and they will probably do it for free............. Quote Link to comment Share on other sites More sharing options...
