Magnetic-Ride Damper Leaks and Rear Wishbone Failures
ModerateSuspension & ChassisAuto Express' used guide warns the R8's magnetic-ride dampers can leak fluid, with owners tempted to fit pattern parts while rebuild specialists exist precisely because the Audi units give up; Autocar's buying guide goes further on the suspension: steel nuts and bolts seize, and a lower rear wishbone can fail in a way that needs a whole new unit - an expensive fix - on both generations. R8s are sensitive to worn bushes and tyre wear, so a knocking or drifting R8 is telling you something rather than being 'just low'.
Oily crust or wet streaks down a damper body, Uneven or harsh rebound after dips and speed cushions, Knocks from the rear corners over joints, Steering that wanders on camber changes
- Shine a torch down each damper behind the wheel arch liners for fresh oil
- Accelerate and brake firmly during the test drive, listening for knocks from the rear
- Check the seized-steel-fastener area on any car that has lived outside the UK salt belt, and ask what wishbone work was done
