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.

When is ABS pump A0034319412 the right choice for your Mercedes W203?
Used ABS pump with control unit, number A0034319412, inspected before sale. Matched by the numbers on the block and sticker.
How to identify ABS pump A0034319412 for your Mercedes W203
This module is made by ATE. ABS pump A0034319412 is sold together with its control unit, just as it is fitted to Mercedes cars. According to the listing, the pump comes from the Mercedes W203 model.
Numbers to compare
The numbers as written on the labels and as a single string, the way catalogues list them:
- A 003 431 94 12 (catalogue format: A0034319412), Mercedes number stamped on the hydraulic block,
- 10.0204-0251.4 (catalogue format: 10020402514), hydraulic block manufacturer's 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.
What ABS problems can point to
- the ABS warning light comes on after the engine is started and stays on,
- valve or pump motor faults are stored in the control unit memory,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- the ABS warning light comes on together with the stability control warning light.
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.
