Planar Air Suspension Upper Wishbone Damper and Ride Height Sensor Wear
ModerateSuspension & ChassisThe Ghost Mk2 utilizes a world-first Planar suspension architecture incorporating an upper wishbone damper unit mounted directly above the front wishbones alongside three-chamber air springs and stereo road-reading cameras. Driven on potholed UK roads, the upper wishbone dampers and articulated ride height sensors experience heavy cyclic stress. Damper seal weeping or sensor linkage play causes ride height deviations, knocking noises, and suspension fault warnings.
Subtle knocking or tapping noise from front wheelarch when traversing low-speed potholes, Car sitting noticeably lower on one corner after being parked overnight, 'Chassis Function Restricted' or 'Suspension Fault' warning message on digital binnacle, Secondary ride harshness over coarse asphalt, diminishing the trademark magic carpet ride
- Listen for front suspension knocking on a test drive over uneven tarmac and speed humps
- Measure vehicle ride height at all four wheel arches after sitting switched off for 12 hours
- Inspect the upper wishbone damper assembly above the front suspension for hydraulic oil leaks
- Scan the active chassis control module for stored height sensor calibration or air leak codes
