Gen 4 Haldex Pump for Rear Diff Ford Volvo Land Rover - Genuine Haldex (S-TEC)

S-TEC Haldex Generation 4 Rear Diff Pump Kit — DS119863 / 9V4N-4C019-AA / LR075763 / 31256757

The Haldex pump generates the oil pressure that operates the rear differential coupling on Generation 4 all-wheel-drive systems, sending drive to the rear axle when it's needed. On higher-mileage vehicles, or where servicing has lapsed, the pump can wear internally and lose the ability to build sufficient pressure.

A failing pump typically shows up as reduced or lost drive to the rear wheels and a noticeable drop in traction. Fitting a fresh pump restores full hydraulic pressure to the coupling and returns the AWD system to normal operation.

Typical fault codes and symptoms linked to pump failure:

P16671
P16670
P16668
Blocked filter gauze
Complete pump failure

Not every vehicle will show all of these faults – the exact symptoms depend on how far the pump has deteriorated.

Programming required after fitting
A learn/adaptation procedure must be carried out with suitable diagnostic equipment once the new pump is installed – without it, the AWD system will not function correctly.

Every pump in this listing is a S-TEC-boxed unit — genuine Haldex original-equipment specification, so fit, tolerances and hydraulic performance match the unit originally fitted at the factory.

This listing is the S-TEC-supplied unit. Also available as ET2406-BW (BorgWarner).

Frequently Asked Questions

Q: Do I need to fit this myself, or should a garage do it?
A: We'd recommend a qualified technician carries out the job – fitting involves draining the Haldex system, swapping the pump, and running the adaptation procedure afterwards.

Q: What kit do I need to run the adaptation procedure?
A: A professional-grade diagnostic tool with Haldex adaptation/learn functionality for the vehicle in question – VIDA on Volvo, IDS on Ford, or SDD on Land Rover, for example.

Q: Why won't the AWD system work properly straight after fitting?
A: The Gen 4 Haldex pump has to learn the system's characteristics through an adaptation procedure carried out on diagnostic equipment – skip this step and the AWD system won't operate as it should.
