Frequently Asked Questions

What does the Haldex pre-charge pump actually do?

It 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, left unaddressed, eventual Haldex system failure.

How do I know if my van has 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 — check your VIN or contact Eco Torque to confirm compatibility.

Can I fit this pump myself?

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