316i320i320Ci328ci
What does E46 ABS/ASC fault code 113 mean?
Code 113 means a pump unit fault. The cause can be worn brushes in the pump's electric motor, the control box relay or the wiring. In the ATE system, an internal solder fault in the box is also a common cause.
Can the E46 ABS unit be repaired or does it have to be replaced?
It can often be repaired. Loose solder joints can be resoldered, and the electronics can be sent for repair, in which case the hydraulic unit does not need to be replaced. Replacing the pump brushes is possible but awkward.
Does another ABS/DSC unit fit the E46?
The part number does not have to be the same, but the unit must suit the car. ASC or DSC, rear-wheel drive or all-wheel drive and the model year all matter. Units from different model years are not interchangeable.
