Service overview

Supported ECU data transfer, with compatibility checked first.

Bosch MG1 and MDG1 engine ECUs in newer VW, Audi, Skoda and SEAT petrol and diesel models (around 2020 onward). These ECUs are locked, so a used replacement will not work without the original data. We unlock, clone your data to a replacement, or repair your own unit.

Common faults

  • Car will not start – no communication with the engine ECU
  • Used ECU fitted but immobiliser or engine will not start
  • Water damage or failed ECU after an electrical fault

A fault code alone does not prove the ECU has failed. Send the codes and a photo of the label on WhatsApp before ordering.

Questions

Repair, cloning or replacement – which do I need?

If your unit has a repairable fault, repair keeps your original and needs no programming. If it is damaged but readable, cloning to a matching used unit is usually cheapest. If it cannot be read or repaired, we quote a replacement with your data transferred where possible.

Will the car need coding after the work?

Not after a repair or a successful clone – the immobiliser and coding come from your original data. Some units need adaptations reset after fitting.

Does a fault code prove the unit is faulty?

No. Supply, earths, wiring, sensors and actuators can set the same codes. That is why every unit is tested first and you get a written report.

What if my unit is not faulty?

You pay only the bench test and receive the report to show your garage.

Do you remove immobilisers or emissions equipment?

No.

Not sure of the part number?
