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.

Is ABS pump A1644312112 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 A1644312112, 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 164 431 21 12 (catalogue format: A1644312112), Mercedes number stamped on the hydraulic block,
- 10.0204-0501.4 (catalogue format: 10020405014), hydraulic block manufacturer's number,
- A 164 545 09 16 (catalogue format: A1645450916), Mercedes control unit number.
The full numbers matter, including their endings. If in doubt, send us a photo of your pump.
Symptoms of a faulty ABS pump or control unit
- the ABS warning light comes on after the engine is started and stays on,
- the ABS stops working, although basic braking usually remains functional,
- 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.
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.
