Suspension / Ride Height Warning
The air suspension or adaptive dampers have a fault — handling and comfort will suffer.
What it means
An amber icon of a car with up/down arrows at the wheels, or the word SUSPENSION. The car’s air suspension, electronic dampers or ride-height sensors have detected a fault. The car may drop to its lowest setting, rise to its highest, or sag on one corner. Ride quality becomes harsh or bouncy, and handling can be unpredictable.
What to do
- 1Drive gently and avoid high speeds or sharp manoeuvres — the car’s handling is compromised.
- 2If the car has settled low, avoid speed bumps and steep driveways to prevent scraping the underbody.
- 3Check for obvious air leaks — a hissing sound from a wheel arch or the compressor running constantly are tell-tale signs.
- 4Get it diagnosed within a few days. Running the compressor continuously will burn it out.
Likely causes
- •Leaking air spring / air bag (very common on older air-suspension cars)
- •Failed ride-height sensor
- •Faulty air compressor or relay
- •Damaged air lines or connections
- •Electronic damper actuator fault
Rough UK cost
Air spring: £300–£800 per corner. Compressor: £400–£1,200. Sensor: £150–£400.
