Mercedes MD1/MG1 ECU unlock with bFlash

As every tuner knows, recent Mercedes ECUs are unfortunately locked and unsupported by virtually every flashing tool manufacturer. Thanks to the fantastic bFlash R&D team, however, recent Mercedes models can be tuned through a very simple and secure unlocking process.

Important: you must own a bFlash tool to carry out this process. If you don't have one yet, contact our team and we'll get you sorted.

How it works

Order the unlock service

Order a bFlash unlock service right here: https://bflash.eu/store/ecu-unlock. The price depends on the engine:

*With recent Mercedes updates, it is necessary to contact bFlash support (support@bobperformance.com) with an OBD identification carried out with a bFlash tool.

Send the ECU to bFlash

Next, send your parcel containing the ECU to the bFlash team at this address:

bFlash Unlock Center - BR-Performance - BCConsulting (Red Building)
Molenweg 94 unit 3
2830 Willebroek (Blaasveld)
BELGIUM
+32 3 866 11 35

Important: please follow these instructions when shipping your ECU:

• Add a return label (bFlash strongly advises using UPS or DHL).
• Include an info sheet about the car (download the PDF template).
• Mention the invoice reference of your bFlash unlock order(s).
• The ECU must be well protected in the package: bFlash is not responsible for any damage caused during transport.
• Without a return label, bFlash can create one for an additional service charge.
• For customers outside the EU:
  • Tax ID: BE0819957826
  • ECU HS code: 8537.10.9167

Please do not ship an ECU without an invoice or order.

Unlock and return

Once the bFlash team has received your parcel, they will carry out the unlock. Your parcel will be shipped back within 24-48 hours.

To ensure smooth shipping and delivery:

• The package must be delivered to and collected at the bFlash office, not a pick-up point.
• Only UPS guarantees same-day shipping.
• Include all customs documents if necessary.

Program the ECU with the bFlash OBD protocol

Once you receive the ECU, you can program it with the bFlash OBD protocol.

Only have the ECU? No problem: the bFlash team will supply a schematic so you can program it directly through the ECU connector. Reading is not possible, so the bFlash team will provide you with the read file at the time of the unlock.
