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 ABS pump with control unit, number A0064312312, inspected before sale. Matched by the numbers on the block and sticker.
Is ABS pump A0064312312 the right part for your Mercedes?
ABS pump A0064312312 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.
Where to find the numbers on an ABS pump
Below are the numbers as they appear on the labels, together with the single-string form used in catalogues:
- A 006 431 23 12 (catalogue format: A0064312312), Mercedes number stamped on the hydraulic block,
- 10.0212-0095.4 (catalogue format: 10021200954), hydraulic block manufacturer's number,
- A 204 545 44 32 (catalogue format: A2045454432), Mercedes control unit number.
Check the numbers on your pump and compare them with those above. If any of them differs, contact us before ordering.
What can point to an ABS pump failure
- the brake pedal pulses or feels uneven for no obvious reason,
- the pump motor switches on at unusual moments or runs louder than usual,
- the ABS activates for no reason during normal braking,
- brake fluid leaks from the hydraulic block, which requires immediate action.
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
| Where do I find number A0064312312 on my pump? |
|---|
| The numbers are stamped or printed on the aluminium hydraulic block, and the control unit has a separate sticker. Take a close-up photo of both places in good light. |
| 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. |
| Does a lit ABS warning light always mean a faulty pump? |
| No. Read the fault codes first, because the cause may be a wheel sensor, its wiring or too low a supply voltage. |
| What condition is this pump in? |
| It is a used original part, inspected before sale. You will find the warranty period in the product features table. |
