A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

Bosch ABS unit 2Q0614517AQ / 0265294493 - Audi, Volkswagen, Seat
In unit 2Q0614517AQ, it is Bosch control module 0 265 956 687 that manages things under heavy braking. It monitors wheel speed, and when one wheel begins to lose grip, the valves in the hydraulic block briefly limit the pressure in that wheel's circuit. The pump motor then pushes the fluid back and rebuilds braking force. The driver feels this as a pulsing pedal, while the car can still be steered.

Typical signs of ABS unit failure
Trouble with this component usually shows up as:
- ABS and ESP/ASR both inactive,
- a recorded valve fault in the block,
- a warning light that comes on right after start-up.
Before buying, read the fault codes with a diagnostic tool and rule out other sources of the problem - the wheel speed sensors, fuses, wiring, the control module connector and battery voltage. After fitting, the brakes must be bled, and on many cars the module also has to be coded and the ESP sensors given a basic setting.
