Why a bench read is needed
- Continental ECUs need ignition-on for OBD ISN
- All-keys-lost = no ignition-on
- Long-ISN families avoid CAS sync
- Short-ISN families need ECU-to-CAS sync
Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- Need the DME ISN for an all-keys-lost BMW
- Can't read MSD80 / MSV80 ISN over OBD, no key
- Replaced the DME and now it won't sync to CAS
- Locksmith needs ISN to make keys on a CAS4 car
- FEM/BDC unlock needs the original DME ISN
Won't fix:
- Mechanical key cutting (we supply ISN/data, not blades)
- DME tuning, flashing, or repair of a dead ECU
- Non-BMW ECUs
- Comfort-access fob pairing on the car (done at the vehicle)
