Frequently Asked Questions

Is 0AY598549A and DS119866 the same part?

Yes — 0AY598549A is the VAG OE reference and DS119866 is the manufacturer part number for the same Generation 4 pump, whichever brand box it arrives in.

What causes the Gen 4 Haldex pump to fail?

Lack of servicing is the most common cause — degraded Haldex oil stops protecting the pump and clutch pack, and the pump eventually fails, taking AWD engagement with it.

Does this pump need coding or adaptation after fitting?

No programming is needed, but a Haldex adaptation reset with VCDS, OBD11 or an equivalent VAG diagnostic tool is worth doing after the pump is fitted.
