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.

Used ABS pump with control unit, number A0004464889, inspected before sale. Matched by the numbers on the block and sticker.
Is ABS pump A0004464889 the right part for your Mercedes?
This is a used original ABS pump with a control unit for Mercedes cars: an aluminium hydraulic block with valves and a pump motor, with the electronics bolted to it. The main number is A0004464889, and the other numbers from the labels are listed below. 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
You will find the numbers on the labels, while catalogues list them as a single string:
- A 000 446 48 89 (catalogue format: A0004464889), Mercedes number stamped on the hydraulic block,
- 0 265 224 065 (catalogue format: 0265224065), hydraulic block manufacturer's number,
- 0 265 900 033 (catalogue format: 0265900033), 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.
What ABS problems can point to
- the ABS warning light comes on after the engine is started and stays on,
- the ABS activates for no reason during normal braking,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- the ABS warning light comes on together with the stability control warning light.
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.
