Step 1 to Step 3: How does the process start — booking, collection and initial diagnosis?

Here is how the first phase works:

• Step 1 — Contact us: Call 020 8803 1231 or Contact MnF Motors online. We aim to respond within 2 hours. Tell us your symptoms — jerky gear changes, warning lights, limp mode — and we confirm whether a mechatronic fault is likely.
• Step 2 — Free collection (if drivable): If your car is in drivable condition, one of our experienced technicians collects it from your home or workplace in North London at a time that suits you, completely free of charge. If your vehicle cannot be driven, please ask us for a recovery quote.
• Step 3 — Full electronic diagnostic (from £60): On arrival at our N18 workshop, we connect specialist diagnostic equipment to read fault codes specific to your DSG or Mercedes 9G-Tronic unit. We do not guess and swap parts — we confirm the exact fault before any work begins. You receive a written report and a fixed quote.

Once you approve the quote, we move straight to the repair. Call 020 8803 1231 to book your diagnostic today.

Step 4 to Step 6: What happens during the mechatronic repair itself — and how long does it take?

Our technicians, with 25+ years of gearbox experience, carry out every repair in-house:

• Step 4 — Unit removal and inspection: The mechatronic unit is carefully removed from the gearbox. Internal solenoids, pressure sensors and wiring harnesses are inspected individually. Our team identifies whether a rebuild or a quality remanufactured unit is the right solution for your specific vehicle.
• Step 5 — Repair and programming: The unit is repaired or replaced, then coded and calibrated to your vehicle using manufacturer-level software. This step is critical — incorrect calibration causes the same symptoms to return, which is why specialist knowledge matters far more than simply fitting a part.
• Step 6 — Road test and quality check: Every repaired gearbox is road-tested before we consider the job complete. Gear change quality, response times and fault-code status are all verified. We will not return a car until we are satisfied it is right — that is the standard our 4.9★ Google rating is built on.

Most DSG and 9G-Tronic mechatronic repairs are completed within 1–2 working days. We keep you updated throughout. Call 020 8803 1231 if you have a question mid-repair.
