Hi all. I have a 2001 Audi S4 sedan. Over the weekend I was driving and my car suddenly stalled. I was able to start it back up after a few seconds. I pulled over and it stalled out again. It seems that when the car warms up, it doesnt happen. I took it a mechanic (non-dealer) and he said it was a computer failure and needs replacement. Has anyone encountered this issue and is it possible it could be something else. Also, any suggestion on where to buy one... dealer cost $1,100 and I was told not to buy used. Any advice would be helpful. Thanks.

 

look around the classifieds theirs usualy some on there that are chipped

 

Or if you have any chip dealers around you they may have one laying around.

I know the place by me has stacks of b5 ECUs collecting dust.

 

Thanks for the tip. I got some clarification from the mechanic and he said the ECM needs replacement and I have been searching around and the cheapest one I have found was for $600.

 

And if it's chipped then your ultimately getting the ECU free.
