Good evening, friends.
I have an unusual condition on a mini cooper that I was called out to make a key for.
The owner had taken it to have the transmission repaired. They drove the vehicle back, and used it for several days.
After a few days, the vehicle had stopped working. It would crank over, but not start. So they called my coworker out to make a key. We made a key, and it had the same effect, it would crank but not start. Sometimes though, the vehicle dash would light, but there would be no crank condition.
The customer also contacted the dealership. The dealership was able to provide a key, and it has the same results. Door locks work fine, ignition seems to accept the key, and the vehicle cranks, but no start. But same as the key we made, there were times where it wouldn't even crank over.
I went back out to check the vehicle, and attempted to resync cas and DME to no avail. Attempted to clear codes, resync modules again. Then i checked the codes since they were returning. There were several codes, and a few I thought would be significant.
2FD7 EWS Anti tampering
A3B2 Kombi module not receiving signal from CAS
E194 No clamp status via CAN
A3A9
c194
I read the CAS3+ module on the bench and the ECU, and the ISN match. I've attached the files. But I'm not sure if the CAS module is possibly faulty? I have also read it could be the power to the CAS module via a bad fuse, but I was able to read and program the keys via OBD, so I would imagine the module is getting power?
As an aside, I did find a function on the IM608 for a cas module renew, but it requires the EGS ISN. I am not with the vehicle, it is a couple hours away, but that value should be in the CAS dump already?
