I have a bangernomics e90 that has given its ecu a bath.
I have it drying out in the hot press but I think I will need to replace it.
Can anyone inform me what exactly will I need from another car and what work will have to be done to make it communicate with the car?
I take it I'll need the ecu, key(s), key reader, immobiliser box (Cas unit?)
If I get all the above from the one car will I still need it coded to my car/other units?
I have access to Inpa but I'm not competent with it.
If anyone could help me I'd be greatful.
