What is PCC III Accumulator Wear on the McLaren McLaren 750S?

The 750S uses ProActive Chassis Control III, an evolution of the 720S system. The hydraulic accumulators remain a consumable wear item with a similar 3-5 year or 15,000-25,000 mile replacement interval. Failure results in a harsh ride and suspension fault warnings.
