Do you own a BMW with a 5DF0 & 5DF1 DSC malfunction fault?

BMW 5E20 DSC

These symbols indicate that your vehicle’s ABS and Traction Control system has shut down due to a fault. We have seen a influx of vehicles with these fault codes stored:

  • 5DF0 Hydraulic unit: pump motor.
  • 5DF1 Hydraulic unit: pump motor connector fault.

As these vehicles age the ABS/DSC pump motor begins to seize. The pump housing is a one time press fit hindering the option to repair without specialist equipment. As such BMW will only replace the whole ABS unit with a bill of around £2500. We do however have a solution.

We have these hydraulic units repaired by a braking specialist. The money saving is huge, however the vehicle is off of the road for around 3 weeks whilst the specialist repair is under way.

So what do we do?

  • We plug our BMW diagnostic equipment into your vehicle, allowing us to diagnose and confirm the fault, we are looking for a 5DF0 & 5DF1 fault.
  • We remove ABS hydraulic unit and send it for specialist reconditioning.
  • Upon return of the newly refurbished ABS hydraulic unit, it is refitted to the vehicle.
  • Bleed the braking system with new DOT4 brake fluid.
  • The unit is then setup and coded the vehicle.
  • We read and clear all stored vehicle fault codes.

This 5DF0 & 5DF1 fault usually affects the following 6-cylinder models:

  • E82, E83, E87, E88 – 1-Series.
  • E90, E91, E92, E93 – 3-Series.
  • E85 Z4’s.
