Same-Day On-Site Service
We understand how important your vehicle is to you and that long workshop visits as well as unnecessary costs should be avoided.
For this reason, we offer our convenient on-site service:
After purchasing the service, simply schedule an appointment at a time that suits you. We carry out the required adjustment directly on the control unit on the same day.
With no long waiting times, the processing time is approximately 2 to 4 hours, depending on the selected option, so your vehicle is ready on the same day.
For this, please select “Pickup” in the shipping options.
Service by Shipping
Unable to visit us in person? No problem. You can conveniently send in your control unit.
Please print out your order confirmation and include it in the package — this is the only way we can correctly assign your ECU to your order.
All shipping costs (both to and from us) are the responsibility of the customer.
You can select your preferred return shipping option during the ordering process.
The following options are available for return shipping.:
- DHL Standard (insured up to €500)

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.
Rules and Conditions
- 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.
