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.

Terms of Service

• In very rare cases, the unlock may not be possible due to the software version on your ECU. Unfortunately, this can only be determined during the unlocking process. If this happens, you will receive a full refund for the service – however, shipping costs are not refundable.
• The customer assumes full responsibility for the shipment while in transit. We do not accept liability for lost or damaged packages.
• Only original, unopened ECUs are accepted.
• Previously opened, tampered with, or modified ECUs will not be processed under any circumstances.
• If any manipulation is detected, or if the control unit has been previously opened, modified, or is not in its original condition, the service will not be performed. In such cases, no refund will be granted.
