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 0265258041: hydraulic module with control unit
ABS pump 0265258041 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 from the listing, as written on the labels and as a single string:
- 0 265 258 041 (catalogue format: 0265258041), hydraulic block manufacturer's number,
- 0 265 956 940 (catalogue format: 0265956940), control unit number,
- A 177 900 80 05 (catalogue format: A1779008005), 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
- the ABS stops working, although basic braking usually remains functional,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- the ABS switches itself off shortly after the engine is started,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
ABS faults should not be ignored, because without anti-lock protection the car brakes less well on wet or slippery roads. Diagnosis and fitting are best left to a garage with a suitable scanner.
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 make and model of the car enough to choose the part? |
| No. A single model comes with different versions of the module, depending on the engine, year of manufacture and drivetrain. The most reliable reference is the number on the original pump. |
| 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. |
| What condition is this ABS module in? |
| It is an original recycled part in good condition, checked by us. Warranty details are in the product features table. |
