Frequently Asked Questions

What causes the Haldex pump to fail on the VW Crafter?

Most commonly a blocked filter gauze inside the pump restricts oil flow, forcing the pump to work harder until it fails — keeping up with Haldex oil and filter changes is the best prevention.

What fault codes indicate a Haldex pump failure on the VW Crafter?

P16671, P16670 and P16668 are the fault codes most commonly logged when hydraulic pressure within the Haldex AWD coupling drops on the Crafter.

Does this pump need programming after fitting?

Yes — after installation, run a Haldex adaptation and clear any stored fault codes with VCDS or an equivalent diagnostic tool to confirm the AWD system is engaging correctly.
