Air Suspension Woes: A Smooth Ride Interrupted

The air suspension system, designed to provide a luxurious ride, can be a source of trouble in older Jaguar XJs. Leaks, compressor failures, and sensor problems can lead to a bumpy ride and uneven ride height.

• Air Leaks: Slow leaks in the air suspension system can cause the car to sit lower than normal, especially after being parked for extended periods.
• Compressor Failure: The air compressor, responsible for inflating the suspension, can fail due to wear and tear or electrical issues.
• Sensor Problems: Height sensors, which monitor the position of each wheel, can malfunction, leading to an uneven ride.

Why is air suspension maintenance so important? Neglecting it can result in costly repairs down the line.
