Where on my 1995 E320 Coupe is the ECU located? Is it deep behind the battery?

It IS behind the battery. They should be covered with a plastic screen and hidden, but techs often do not replace the plastic screen.

It is the one with two large plugs on it.

You will need to take battery out, so log your radio code (perhaps), and when refitting battery (after ECU repaired), the alarm is likely to go off.

Do not re-install the ECU without the new wiring loom and the 3xcoils checked for shorting or it could "blow" again.

It will be the output driver transistors in the ECU and not everyone is capable of repairing the type you have. Get the quote in writing first, after you have given the repairer the part number and type of ECU.

Top marks on the location! I have sent it away for repair. So here is hoping. Also my motor electrician is happy he can repair and not replace the loom. Am I too hopeful for the longevity of the work? Or should I simply pay the cash and replace?

Anyone want to buy a 1980 450SL LHD?
