Audi R8 Gen 5 Haldex Pump AWD Coupling 0D4906271A - Genuine Haldex (S-TEC)

Audi R8 Gen 5 Haldex Pump — AWD Coupling 0D4906271A (S-TEC)

The Haldex pump generates the hydraulic pressure that engages the rear coupling on Gen 5 Haldex all-wheel-drive systems, feeding drive to the rear axle. On higher-mileage R8s — especially where routine Haldex servicing has lapsed — the pump's internals can wear or fail, cutting rear-wheel drive and reducing traction. Typical warning signs include fault codes P16671, P16670 and P16668, a blocked filter gauze, or complete pump failure; you may see some, but not necessarily all, of these depending on the extent of internal wear.

This listing is supplied as a S-TEC-boxed unit — genuine Haldex original-equipment specification — built to the same fit, form and function as the pump originally fitted at the factory.

This listing is the S-TEC-supplied unit. Also available as ET2327-BW (BorgWarner).

Parts Included

Rear differential Haldex pump, plus the two mounting screws needed for fitment.

Please note: a new pump must be programmed via the Haldex learn procedure once fitted — confirm your diagnostic equipment supports this feature before ordering, or the replacement pump will not operate correctly.
