The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.

How a damaged hydraulic unit shows itself
Trouble with the hydraulic unit usually shows up as:
- ABS and ESP/ASR switched off at the same time,
- a fault on one of the valves stored in the control module,
- ABS warning light on from the moment the car is started.
Fault codes read with a diagnostic tool are the starting point; at the same time, check the wheel speed sensors, fuses, wiring and connector, and the battery condition. After replacing the hydraulic unit, bleed the brakes, then code the control module and calibrate the ESP sensors – on VW Group cars this is usually necessary.
