Mercedes Models from 2020 Onwards
Vehicles equipped with MD1/MRD1 feature a highly protected engine control unit that must be unlocked before any ECU tuning can be performed. When purchasing this service, the ECU unlock is already included at no extra cost. The ECU unlock is only used internally so we can carry out the required work. You will not be able to tune the ECU yourself. If you want to unlock the ECU for self-tuning, please choose our separate Unlock Service.
