Frequently Asked Questions

What does the Haldex pre-charge pump do?

The pre-charge pump builds hydraulic pressure in the Haldex unit to pre-load the clutch pack, enabling faster AWD engagement. A failed pump causes delayed or absent AWD activation and eventual Haldex system failure.

Is this a genuine part?

Yes. DS118622 is the BorgWarner OEM reference; this listing is the S-TEC-supplied unit — genuine original equipment. We also stock the BorgWarner version under ET2266-BW.

How do I know if I have a Gen 2 or Gen 3 Haldex system?

The generation is determined by the vehicle model year and platform. VW Transporter T5 and Multivan models generally use the Generation 2 system. Use your VIN or contact Eco Torque to confirm compatibility.

Should the Haldex oil and filter be replaced at the same time?

Yes. Always replace the Haldex oil and filter when fitting a new pump to prevent contamination from reaching the new unit and to maximise service life.

Can I fit this pump myself?

The Haldex pump is accessible without full transmission removal, but requires correct torque settings and a Haldex oil flush. We recommend installation by a qualified technician.
