Bosch 5.7 broken

The Bosch 5.7 is one of the best-known and most popular ABS units. The complaints that occur with the Bosch 5.7 are diverse, but a large part of the defects can be traced back to wheel sensor errors, pump motor problems and communication problems.

Problems with the Bosch 5.7

The following problems and error codes often occur with the Bosch 5.7 ABS unit:

• Errors of the wheel sensors
• No communication with the ABS
• Errors with the brake pressure sensor
• Error with the pump motor (BMW)
• Error with the printed circuit board

Vibrations and temperature fluctuations play a role in malfunctions of the Bosch 5.7 ABS. In some cases, the problem is not in the ABS unit itself, but in the connectors of the ECU. 

Bosch 5.7 repair

Each ABS module consists of three components: the pump motor, the HCU and the ECU. These three components ensure that the ABS unit can function optimally. ACTRONICS only accepts the entire ABS unit, even if the diagnosis shows that one of the components is defective. We test the entire unit in our own test setup. This allows us to make the correct diagnosis, check all functions and perform a final test.
