Hydraulic Haldex Pump 5th Generation BMW Mini Haldex Repair Kit 8663457 / 33108663457 - BorgWarner

BorgWarner 5th Generation Haldex Pump — BMW & Mini — 8663457 / 33108663457 / DS2010677

On BMW and Mini all-wheel-drive models the Haldex pump builds the hydraulic pressure that engages the rear coupling. Once mileage climbs or servicing lapses, this pump is one of the first things to wear out, and when it does the rear axle simply stops receiving drive.

This listing is supplied as the BorgWarner-boxed unit; BorgWarner is the OEM behind the Haldex system.

This listing is the BorgWarner-supplied unit. Also available as ET2083-ST (S-TEC).

Frequently Asked Questions

Is this an OEM-quality kit?

What is included in this Haldex pump kit?

You receive the complete Haldex hydraulic pump assembly together with the two fitting screws, so the failed component that pressurises the rear coupling is fully replaced.
