Preload pump rear axle Haldex Borgwarner 5th generation 0CQ598549

Why replace your Haldex pre-charge pump?

On 5th generation Haldex systems, the absence of an external oil filter often leads to the accumulation of residue (clutch "sludge") that clogs the pump strainer. If not replaced, you will lose all-wheel drive traction, turning your vehicle into a simple front-wheel drive car.

• OEM Quality: Original part strictly identical to the one fitted at the factory (BorgWarner is the official manufacturer for Audi/VW).
• Safety: Guarantees immediate torque distribution to the rear wheels in the event of a loss of grip.
• Complete Kit: Delivered ready to mount with its 2 fixing screws and sealing gaskets.
