I have been having a long lasting problem with my ASR which the diagnostic codes indicate is the ECU (Electronic Actuator). I am shopping for a used ECU for a 1992 400E. Does anyone have the Mercedes Part number
I wish to search out sources via the net. The dealership, being real helpful doesn't wish to give it to me. Lastly, does anyone know if later year E420s have the same ECU and, are they interchangeable with my model and year? Thanks all!

Very RARELY is the ECU for the electronic accelerator a problem! ALMOST always when you get a code for EA ECU being defective it is the EA actuator (throttle body) causing the problem!!

The part number is dependant on the VIN of the car!
