BMW ABS/DSC Pump – Causing ABS, DSC and Handbrake warning light fault

This BMW ABS/DSC pump is a very common failure for the BMW 3-Series (E90), Z4, 1-series and M5 built between 2005 and 2014. The common symptom is that the ABS, DSC and handbrake warning lights remain permanently illuminated. If you have performed a diagnostic scan then you will also have the following fault codes stored within the ABS system; “5DF0-Hydraulic Unit Pump Motor” and “5DF1-Hydraulic Unit Pump Motor Connector Faulty” these fault codes may clear initially but they will always return and become a permanent fault. A new unit from the manufacturer is very expensive and only comes with a short 1-year warranty.

We are able to rebuild customers own unit in 2-3 working days or supply replacement units from stock at a fraction of the cost of a new unit from the manufacturer, plus the new unit will still have the original design flaw that caused it to fail in the first place.

Every BMW ABS pump that we rebuild comes with an unlimited mileage lifetime warranty as standard – we can do this because we use higher rated than standard components during the rebuild process, so you can be sure that your ABS unit will not fail again.

Test and rebuild:

Every BMW ABS unit is fully tested on our bespoke HIL (Hardware In-the-Loop) test rig both before and after the rebuild process. This involves simulating real driving conditions including wheel speed, body roll, accelerometer, steering input and brake pressure. We test every unit beyond the operating parameters of the vehicle so we know that once a unit is rebuilt it will outlast the vehicle. This is how we can supply an unlimited mileage lifetime warranty with every BMW ABS pump we rebuild and supply.

Programming:

This ABS unit is coded to the vehicle, through out testing and rebuild all programming information is retained, meaning that there is no need for coding when you receive the unit back.
