The mechatronic unit is the electronic and hydraulic brain of your DSG gearbox. We diagnose and repair mechatronic faults across Audi, Volkswagen, SEAT and Skoda vehicles.
Overview
What Mechatronic Repair Involves
The mechatronic unit combines the transmission control module, valve body, solenoids and clutch position sensors into a single assembly. When any of these components fail, the gearbox can misbehave in ways that are often mistaken for a much bigger problem.
We test the unit on the bench and in the vehicle, identify the specific faulty component, and repair or replace it as needed — avoiding the cost of an unnecessary full unit swap wherever possible.
