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.

Mercedes ABS pump: numbers A2054311400 and 0265256697
ABS module A2054311400 is used and has been inspected before sale. It is intended for Mercedes cars, but whether it fits is decided by comparing the numbers with the original part in your car. 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
Below are the numbers as they appear on the labels, together with the single-string form used in catalogues:
- A 205 431 14 00 (catalogue format: A2054311400), Mercedes number stamped on the hydraulic block,
- 0 265 256 697 (catalogue format: 0265256697), hydraulic block manufacturer's number,
- 0 265 956 109 (catalogue format: 0265956109), 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 can point to an ABS pump failure
- the ABS stops working, although basic braking usually remains functional,
- the brake pedal pulses or feels uneven for no obvious reason,
- the ABS activates for no reason during normal braking,
- brake fluid leaks from the hydraulic block, which requires immediate action.
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.
