NOW AVAILABLE — Mercedes-Benz MRD1 ECU Unlock 🔓

We can now fully unlock the MRD1 (Bosch MD1CP001) ECU on the OM654 (2.0L diesel) and OM656 (3.0L straight-six diesel), 2020 onward.
The unlock is the mandatory first step before any real ECU tuning — and with us it comes the right way:

✅ Full, permanent unlock

✅ Unlocked for life — free re-unlock if a dealer update re-locks it

✅ Remote re-unlock in most cases

✅ Australian-based, no overseas shipping
