Hi all
My 2.7 CRD - same engine as the ML270 (OM647 i think) ecu is blown (I know there will be differences in the ecu, but with this scenario I think my questions will be quite generic to common rail diesels and ecu/pcm's)
I had a case of leaking injectors (black death) and took the vehicle in to a service centre to have the injectors removed, refurbished and the seals replaced, they assured my do this all the time... Any case, week later they contacted me and said they can't get the car started again, my trust in them dissapeared and I had the vehicle dropped off with a flat bed to our local Mercedes Benz/Chrysler dealers.
They inspected the vehicle and found the ECU to be faulty. A new unit has been ordered and should be installed by Thursday next week.
Now the question: what could the previous guys have done to damage the ecu? Maybe shorting injector wires? I know the insulation gets very brittle with the whole black death thing.
