A properly functioning ABS system is the foundation of road safety. Its main task is to prevent wheel lock-up during emergency braking, which allows the driver to maintain full control of the vehicle. The heart of this system is the electronic ABS pump controller. When it fails, the system stops working. A proper diagnosis of the problem allows you to avoid unnecessary costs and quickly restore brake efficiency.

How to check whether ABS pump A2054314412 fits your Mercedes
Used ABS pump with control unit, number A2054314412, inspected before sale. Matched by the numbers on the block and sticker.
Is ABS pump A2054314412 the right part for your Mercedes?
If the ABS warning light is on in your Mercedes, one possible cause is the hydraulic module or its control unit. ABS pump A2054314412 is a used original part, inspected before sale. 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
The numbers as written on the labels and as a single string, the way catalogues list them:
- A 205 431 44 12 (catalogue format: A2054314412), Mercedes number stamped on the hydraulic block,
- A 205 901 29 00 (catalogue format: A2059012900), 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.
Symptoms of a faulty ABS pump or control unit
- the ABS stops working, although basic braking usually remains functional,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- the ABS warning light comes on together with the stability control warning light,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
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.
