Hello guys,
I'm trying to repair a BMW 3 Series E91 which doesn't start,
It's doesn't try to start, basically, when I try to start the car, it's only turn ignition on and off.
I've tested with a different set of ECU+CAS+KEY and then, car works fine!
I also cloned another CAS for this fault one and it started to works fine in a different car (So, it's not a hardware issue)
If I try to change flash of the fault CAS, it doesn't change it's behaviour, but I tried to program with an EEPROM of different car and it start to crank the engine, but obviously, doesn't starts cause it isn't matched for this DME.
I think the problem happened when someone tried to program a new key, because the owner bought this car like this, with 2 original keys and a 3rd one brand new.
I wish I could fix only this EEPROM, because I've no equipment to program keys, make this 3 keys virgin again, etc.
I also need to change VIN of this DME and CAS, DME seems I'll be able to do it using a K DCAN Cable, but I'm unsure if I can do the same for this CAS and I'm also questioning if I change VIN on this CAS, what gonna happen to the VINs recorded in this keys?
If someone could light my way about this, I'll be really thankful and I also can pay for the corrected EEPROM if it's possible to be fixed.
