Hello,
I have a F10 here with bad valvetronic system. We swapped DME and CAS and key with a USED set from a F25 to test if the ECU driver is faulty for the valvetronic system. However when we re-install the original CAS DME and key, the vehicle now identifies as the donor F25 VIN.
Question is how do I re enable the original VIN? When connected to ISTA+, the VIN is incorrect.
Does ISTA+ read the VIN from another module such as the FRM?
Thanks!
Robby
