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.

What does number A0034312412 on an ABS pump mean?
Used original ABS module with number A0034312412 for Mercedes. Confirm compatibility with the number from your original pump.
How to identify ABS pump A0034312412 for your Mercedes
ABS pump A0034312412 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 A0034312412 and related numbers
The numbers as written on the labels and as a single string, the way catalogues list them:
- A 003 431 24 12 (catalogue format: A0034312412), Mercedes number stamped on the hydraulic block,
- 0 265 202 407 (catalogue format: 0265202407), hydraulic block manufacturer's number.
The full numbers matter, including their endings. If in doubt, send us a photo of your pump.
What ABS problems can point to
- the ABS warning light comes on after the engine is started and stays on,
- the pump motor switches on at unusual moments or runs louder than usual,
- the ABS warning light comes on together with the stability control warning light,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
First check the wheel sensors, their wiring and the supply voltage. Only a fault code pointing to the module justifies replacing the pump. After fitting, clear the fault codes and, if necessary, bleed the brake system.
