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.

Let us start with what the entries in this listing mean. Number 8E0614111M is the VAG designation of the whole ABS unit, and 0 265 220 441 is the number Bosch uses to describe the hydraulic block with the pump. The control module has its own Bosch number, 0 273 004 134, with no VAG number in our data. Since the first two numbers are visible on the block, that is where the comparison begins.

Symptoms that call for a look at the pump
Damage to the ABS assembly is usually signalled by:
- the ABS warning light on together with the ESP lamp,
- ABS inactive during braking,
- a pump fault stored in the control module memory.
First read the faults with a diagnostic tool, then check the wheel speed sensors, fuses, wires, the plug and the battery, because even a faulty sensor produces a similar picture. After fitting the assembly, bleed the brakes and, if the car requires it, code the control module with a diagnostic tool.
