Gen 2 Haldex Pump — AWD Coupling

0AV598549A / 30783079 / SP03157 — S-TEC

This is a genuine Haldex Generation 2/3 oil pump for the AWD coupling fitted to VW, Audi, Seat and Skoda all-wheel-drive models. The pump pressurises the coupling to control torque split between the front and rear axles; when it wears or fails, expect reduced AWD performance, Haldex-related fault codes, and — left unaddressed — full coupling failure.

This is an S-TEC-boxed unit — genuine Haldex original-equipment specification.

This listing is the S-TEC-supplied unit. Also available as ET3193-BW (BorgWarner).

Frequently Asked Questions

Q: What tells me the Haldex pump has failed?
A: Watch for reduced traction in AWD mode, a Haldex clutch pressure fault code, and the system defaulting to front-wheel drive. A VCDS or OBD scan will confirm a pump-related fault.

Q: How do Gen 1 through Gen 4 Haldex units differ?
A: Gen 1 (1998–2002) uses an external pump bolted to the coupling. Gen 2 (2003–2007) and Gen 3 (2007–2012) share an internal pump design. Gen 4 (2012 onwards) introduced a further revision. Confirm which generation is fitted before ordering.

Q: Should I replace the Haldex oil when I replace the pump?
A: Yes — replacing the oil and filter alongside the pump is strongly recommended to keep the system clean and maximise the new pump's service life.
