The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.

Will ABS pump A0074314412 fit your Mercedes?
Used ABS pump with control unit, number A0074314412, inspected before sale. Matched by the numbers on the block and sticker.
Is ABS pump A0074314412 the right part for your Mercedes?
This module is made by Bosch. ABS pump A0074314412 is sold together with its control unit, just as it is fitted to Mercedes cars. 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 A0074314412 and related numbers
You will find the numbers on the labels, while catalogues list them as a single string:
- A 007 431 44 12 (catalogue format: A0074314412), Mercedes number stamped on the hydraulic block,
- 0 265 251 313 (catalogue format: 0265251313), hydraulic block manufacturer's number,
- 0 265 951 386 (catalogue format: 0265951386), control unit 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 brake pedal pulses or feels uneven for no obvious reason,
- valve or pump motor faults are stored in the control unit memory,
- the ABS activates for no reason during normal braking.
Before buying a module, read the fault codes with a diagnostic tester. A faulty wheel speed sensor or its wiring can cause the same symptoms, and in that case replacing the pump will not help. After replacement the fault codes usually need to be cleared, and if the brake lines have been disconnected, the system must be bled.
Questions and answers
| Where do I find number A0074314412 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. |
| 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. |
| 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. |
