I have a 320d 2005 e90 it cut out + vehicle electronics failure light came on had it code read no contact to ecu found water in ecu + corrosion was told ecu needed replacing so got key cas unit + ecu of a running car fitted all to mine ignition comes on but won't crank do I need any other parts cheers

Any one

At a guess, the new modules will require coding to your car. That said, the cas and are the two most important modules so I'm not sure how you'd code them. Normally you code other modules off the back of the cas and ecu!

I'll do some research if I get the chance. Might be worth asking in the main site 'coding' subforum.
