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.

Mercedes ABS pump 0265255863: hydraulic module with control unit
This module is made by Bosch. ABS pump 0265255863 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.
Numbers and markings on the ABS pump
The numbers as written on the labels and as a single string, the way catalogues list them:
- 0 265 255 863 (catalogue format: 0265255863), hydraulic block manufacturer's number,
- 0 265 956 032 (catalogue format: 0265956032), control unit number,
- A 906 900 88 03 (catalogue format: A9069008803), Mercedes 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
- valve or pump motor faults are stored in the control unit memory,
- 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,
- the ABS switches itself off shortly after the engine is started.
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.
Questions and answers
| 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. |
| Can I send a photo for a compatibility check? |
| Yes. Contact us and send a photo of the numbers on your original pump, and we will help you check whether this module will fit. |
| 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. |
