Repair an ATE MK25?

The ATE MK25 ABS unit is used by various car manufacturers like: Audi, Volkswagen , Mercedes and many others. The faults that occur differ per car make and model. The faults in an ATE MK25 are mainly caused by bad wiring or a defective pump motor. ACtronics has a remanufacture solution available for a faulty ABS unit.

Possible defects and fault codes

In general two types of complaints occur: errors on the pump motor and loss of communication with the ABS unit. The complaints show while driving: the ABS warning light will come on. In addition to the ABS warning light, the live data will show if the ABS Unit still receives data from the wheel sensors.

Remanufacture solution for the ATE MK25

Before an ECU is remanufactured by one of our engineers, an entry test is first performed. Depending on the results of this test, a remanufacture solution will be performed. The defective and weak components may or may not be replaced preventively to improve the service life. Before a unit is returned, a final test is carried out to verify that the defects have been resolved and the unit is operating properly again.
