Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓DSM/ISM failed — no shift, stuck in Park, no crank
- ✓Installed a used DSM/ISM and the car will not accept it
- ✓Drive-authorization / start fault after a shifter module swap
- ✓Want to keep your existing keys on a newer Mercedes
Won't fix:
- ✗FBS4 EIS or key programming — NO aftermarket tool can do this; it is dealer-only and we never claim it
- ✗Original module with no readable data (nothing to clone — contact us)
- ✗Mechanical transmission or shifter-linkage faults
- ✗FBS3 (pre-2013) cars — see our 722.9 conductor plate service
On FBS4, cloning is the only path — and it works
Newer Mercedes drive-authorization modules cannot be virginized and adapted the way older ones can; the only viable route is a full clone — reading the internal boot, EEPROM, and flash from your original and writing them to a donor. That is exactly what we do, and the donor comes out behaving as your original, keys intact. The one thing no aftermarket shop can do on FBS4 is the EIS and keys — that stays with the dealer, and we will always tell you so.
