Mechatronic Repair and Cloning Service UK | The Vehicle Check

The Vehicle Check is one of the UK's leading specialists in mechatronic repair and cloning. We accept units by post from anywhere in the UK and internationally, or by drop off in person at our Enfield office. Every repair is carried out by experienced technicians with full bench testing before return.

What is a Mechatronic Unit?

The mechatronic unit is the brain of your automatic gearbox. It combines electronic control and hydraulic valve body functions into a single integrated unit, managing gear selection, shift timing, pressure regulation and clutch engagement. When the mechatronic unit develops a fault, the gearbox will typically default to limp mode, become stuck in a single gear, refuse to engage drive or reverse, or produce erratic shifting behaviour.

Mechatronic failure is extremely common across the VAG group — affecting Mercedes, Audi, VW, Seat and Skoda vehicles fitted with DSG, S-Tronic, 7-speed and CVT transmissions. Main dealer replacement costs can exceed £2,000. A professional mechatronic repair or cloning service from The Vehicle Check offers a reliable, cost-effective alternative.

Mechatronic Repair vs Mechatronic Cloning — What is the Difference?

Mechatronic Repair

Your original unit is diagnosed, faulty components are identified and replaced at component level, and the unit is fully bench tested before return. This is the preferred option when your original unit is repairable and you want to retain the original matched unit for your vehicle.

Mechatronic Cloning

Where your original unit is beyond economical repair, we clone all data from your original unit onto a tested replacement unit. The cloned unit is plug and play — no programming, no dealer visit required. This is the most cost-effective solution when the original unit cannot be salvaged.

Frequently Asked Questions

Is it safe to post my mechatronic unit?

Yes. Thousands of customers post automotive electronics to specialists every day using Royal Mail Special Delivery or tracked courier services. We recommend double boxing the unit and including your contact details and vehicle registration inside the package.

What if my unit cannot be repaired?

If your unit is beyond economical repair we will contact you before proceeding. We will advise whether cloning onto a replacement unit is possible and provide a quote. We never carry out work or incur additional charges without your authorisation.

How long does mechatronic repair take?

Most mechatronic repairs and cloning jobs are completed within 3 to 5 working days of receiving your unit. We will confirm an estimated turnaround when we acknowledge receipt of your unit.

Will the cloned unit need programming at the dealer?

No. Cloning transfers all data from your original unit to the replacement unit including all vehicle-specific calibration data. The cloned unit is plug and play — simply refit it and the vehicle will operate normally with no dealer visit or additional programming required.

Do you offer a warranty on mechatronic repairs?

Yes. All completed repairs and cloning work carries a warranty. If you experience any issue with a repaired or cloned unit within the warranty period, contact us immediately and we will resolve it.
