I've tried searching through the forums and haven't found a topic like this yet. Is there any way to get fully detailed electrical schematics for Audis? I have a 2004 A4 that has some sort of electrical problem. It throws anywhere from 1 error code to 14 different error codes but the result is the same, the throttle is unresponsive and on occasion the car stalls. It's not a consistent problem but comes and goes. I've had two Audi certified shops look at it but neither shop has been able to figure out the problem. Being an engineer I figured if I could find copies of the schematics, I could just troubleshoot it myself and avoid paying them for just resetting the ECU every couple months.

Thanks in advance,
Tom
