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.

Used original ABS module with number A0004463289 for Mercedes. Confirm compatibility with the number from your original pump.
Used Mercedes ABS pump with number A0004463289
ABS pump A0004463289 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.
Numbers and markings on the ABS pump
The numbers as written on the labels and as a single string, the way catalogues list them:
- A 000 446 32 89 (catalogue format: A0004463289), Mercedes number stamped on the hydraulic block,
- 0 265 224 040 (catalogue format: 0265224040), hydraulic block manufacturer's number,
- 0 265 900 020 (catalogue format: 0265900020), 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.
Symptoms of a faulty ABS pump or control unit
- 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,
- 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.
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.
Questions and answers
| Which car model does this pump fit? |
|---|
| The listing does not state a model or year, so confirm compatibility with the number from the original pump in your car, or send us a photo of it. |
| Are the pump and the control unit sold separately? |
| In this listing they are a single module: a hydraulic block with the pump and valves, with the control unit attached to it. |
| Do the brakes need bleeding after replacing the module? |
| If the brake lines are disconnected during fitting, the system must be bled. The fault codes in the control unit usually need to be cleared as well. |
| Is this a new part? |
| No. We sell used original modules, each one inspected before sale. You will find the warranty period in the product features table. |
