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.

Mercedes ABS pump: numbers A0084318712 and 0265242715
ABS pump A0084318712 for Mercedes is a used original module that regulates brake pressure when a wheel starts to lock up. It is matched by the numbers on its labels, not by the car model alone. The listing does not state the car model or year, so we do not give them here and match the part by its numbers.
Part number A0084318712 and related numbers
The numbers as written on the labels and as a single string, the way catalogues list them:
- A 008 431 87 12 (catalogue format: A0084318712), Mercedes number stamped on the hydraulic block,
- 0 265 242 715 (catalogue format: 0265242715), hydraulic block manufacturer's number,
- 0 265 956 032 (catalogue format: 0265956032), control unit number.
Matching by number is more reliable than matching by car model. Compare all the numbers and ask us if any of them does not match.
When an ABS module needs replacing
- the ABS warning light comes on after the engine is started and stays on,
- the ABS stops working, although basic braking usually remains functional,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- the ABS warning light comes on together with the stability control warning light.
It is worth reading the fault codes and checking the sensor wiring before replacement. Fitting and bleeding the brake system are usually carried out by a garage with the right equipment.
