Audi R8 5.2 V10 FSi (Second Generation 2015–onwards) - Haldex Oil Change

The Haldex coupling is a very sophisticated piece of engineering that needs to be looked after with regular oil changes.

The coupling is a submerged multi-plate, wet clutch system that engages upon slip and transfers power to the front final drive. The Haldex Coupling is a separate component from the Rear Final Drive, but is directly attached to it. The system is computer controlled with very fine engineering tolerances. If the Haldex oil is dirty, it will damage other parts and affect performance.

Dirty oil can overheat the coupling or cause the clutches to burn out or burn our the Haldex Pump and will lead to loss of rear drive and eventual failure.

The Haldex pump pre-charges the oil inside the Haldex assembly to allow the coupling to engage faster. This part is prone to failure on higher mileage cars or if regular maintenance in not performed. If your pump is faulty, you may experience loss of engine power to the rear wheels due to the pump becoming contaminated with old fluid and no longer activating..
