Symptoms & Fault Codes

A failing Haldex pump on the VW Crafter will typically present with one or more of the following fault codes: P16671, P16670, P16668. Additional symptoms include AWD warning lights, loss of rear drive engagement, and — in more advanced cases — a blocked filter gauze within the pump assembly indicating internal contamination. Early replacement of the pump prevents further damage to the Haldex coupling and differential.

Programming Requirement

Following installation, the Haldex control unit should be initialised using a suitable diagnostic tool (e.g. VCDS or equivalent). Fault codes must be cleared and a Haldex adaptation/calibration routine performed to confirm correct AWD operation.

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

A: The most common fault codes associated with Haldex pump failure on the VW Crafter are P16671, P16670, and P16668. These relate to hydraulic pressure faults within the Haldex AWD coupling system.

Q: Is this a genuine OE part?

A: Yes. This is a Genuine OE Haldex pump — this listing is the BorgWarner-supplied unit, carrying OE references 0CQ598549A and DS2010678. We also stock the S-TEC version under ET2086-ST.

Q: Does this pump need programming after fitting?

A: Yes. After installation we strongly recommend performing a Haldex adaptation and fault code clear using VCDS or an equivalent diagnostic tool to ensure the AWD system engages correctly and no residual codes remain.

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

A: The most common cause is a blocked filter gauze inside the pump, which restricts oil flow and causes the pump to work harder until it fails. Regular Haldex oil and filter changes are the best preventative measure.
