0CQ598549: the genuine Gen 5 Haldex AWD pump guide

Mind

The 0CQ598549 is the official BorgWarner OEM pre-charge pump for 5th generation Haldex AWD systems, fitted to a broad range of Audi, VW, Seat, and Škoda models sold in the UK. If your AWD system is struggling to engage, or you have a confirmed pump fault, this is the part you need. Not an aftermarket substitute. The genuine article, manufactured by BorgWarner and carrying OEM part number 0CQ 598 549 (also referenced as DS2002773 and 2002773).

UK buyers can source it through authorised distributors, with Haldexparts.co.uk being the specialist UK supplier for this exact component.

What are the specifications and compatibility of the 0CQ598549 pump?

The 0CQ598549 is a pre-charge pump, meaning it pressurises the Haldex coupling before AWD engagement is needed. Without it functioning correctly, the rear axle simply does not receive drive. BorgWarner manufactures it directly from factory, which is why OEM certification carries real weight here rather than being a marketing label.

How do you order the 0CQ598549 in the UK, and what does it cost?

Ordering through an authorised UK distributor is the only reliable way to guarantee you receive a genuine BorgWarner unit. Haldexparts.co.uk stocks the pump and ships across the UK, with free delivery on orders over £150. Delivery typically takes a few working days depending on stock levels.

Pricing varies depending on whether you purchase the pump alone or as a kit with BorgWarner oil G055175A2. Factor in VAT at the standard UK rate, and if you are having the pump fitted professionally, labour costs on top. A one-year warranty applies to replacement parts supplied through authorised channels.

Key ordering considerations:

  • Confirm the part number matches your vehicle before checkout
  • Purchase from an authorised distributor to protect your warranty
  • Orders over £150 qualify for free UK shipping at Haldexparts.co.uk
  • Expect 2–5 working days for delivery
  • A one-year warranty covers genuine OEM replacement parts

Pro Tip: Avoid listings on general marketplaces that do not state BorgWarner as the manufacturer. Counterfeit and pattern-copy pumps exist for this part number, and they will not carry OEM certification or warranty cover.


Replacing the pump in isolation is rarely the complete job. The BorgWarner oil G055175A2 (850ml, part number 2000884) should always be changed at the same time, since old or contaminated oil accelerates wear on the new pump. Haldexparts.co.uk stocks the oil separately and as part of a combined kit.

Beyond the oil, a full service of the Generation 5 system typically involves:

  1. AWD oil filter — the Haldex oil filter traps debris that would otherwise circulate through the new pump
  2. Seal repair kit (0CQ598305) — covers pump seals and O-rings, avoiding a second disassembly if seals are worn
  3. Socket head bolt M6x35 — included in the OEM repair set for the primer pump, useful if fixings are corroded
  4. ECU / control unit check — if the pump failed due to an electrical fault, the control unit may need attention before fitting a replacement

For buyers who want everything in one order, Haldex service kits bundle the pump, oil, and filter together. That approach saves time and removes the risk of forgetting a component. If you are also maintaining sensors on a performance vehicle, Taylor’d Tuning stocks Bosch UEGO replacement sensors compatible with many of the same VAG platform vehicles.
