What we do
- Unlock a locked ME9.7
- VIN write + SCN code to your car
- Clone your original data onto a replacement or donor ECU
- Program a NEW replacement ECU for an M272 or M273 job
- Renew / virginize an FBS3 ME9.7 so it can be coded to your EIS
- Match the immobilizer relationship so your existing keys still start it
Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- Replacement ME9.7 will not start or runs poorly (not matched to the car)
- Used ECU needs VIN writing and SCN coding
- Locked ME9.7 that needs unlocking for work
- Want your original data cloned so keys carry over
Won't fix:
- Mechanical engine faults or wiring that mimic ECU failure
- EIS/key faults where the ECU is fine (separate service)
- Diesel CDI or non-ME9.7 controllers — send your VIN, we confirm
- Performance tuning (this is factory SCN/coding work)
- Dead, burnt, water-damaged, or no-OBD-communication ME9.7 — there is nothing to read, so see our Advanced ECU / Module Recovery service instead
- FBS4 (2015+) EIS or key programming — that is dealer-only, with no aftermarket path
One bench service for the whole ME9.7 job
Whether you bought a used ECU that will not start the car, need a locked unit opened, want a brand-new M272 or M273 replacement programmed before it goes in, or want your original data cloned onto a replacement so nothing has to be re-keyed — it is all the same bench station. Tell us the situation and your VIN and we do the right operation: unlock, VIN write + SCN, renew to virgin, or clone. You are not paying for four services; it is one flat price. The one case this page does not cover is an ME9.7 that will not answer at all — dead, burnt, flooded, or no OBD communication. A clone needs a readable original, so those go to our Advanced ECU / Module Recovery service, where the board is repaired and the memory read directly before any identity is transferred.
