I have been having problems with the EPC light coming on and the engine stalling. Read other threads on the forums and it looks like people have had success with replacing the engine speed (rpm) sensor.

I have a 2008 A6 and can't find a compatible part that is called a speed sensor. Mostly just finding ABS sensors. Anybody know if this is a valid part for this model?

Or, any other suggestions to help with the EPC light/stalling problem?
