Adaptive air suspension is standard equipment and the biggest 7 Series claim category
SeriousSuspension & ChassisThe i7 rides on standard adaptive air suspension that can raise the nose by 20mm for steep drives and XXL speed bumps and lowers at motorway speed, with an optional active anti-roll system. That is also the region where 7 Series warranty money goes: suspension accounts for 33.9 per cent of claims on the nameplate with an average repair of £1,027, the largest single category by a wide margin. For a UK buyer the practical risks are perished air springs, failed height sensors, a compressor working too hard and salt-driven corrosion of the mountings around our wheel arches.

- Cycle the suspension through every height mode on the viewing and listen for compressor labelling or hesitation
- Ask for the height readings from a diagnostic tool and check the car sits level
- Inspect the air spring bellows for cracking and the surroundings for winter salt corrosion
- Confirm whether any suspension work is covered by remaining factory or certified warranty
