Known JLR Fault
Common Land Rover Air Suspension Faults & Solutions
Affects
Overview
Air suspension is fitted to most Range Rover, Range Rover Sport, and Discovery 3/4 models as standard. While it provides exceptional ride quality and off-road capability, the system has several well-known failure points that are particularly common in the UK's cold and wet climate.
Symptoms
- ▶Vehicle sitting lower than normal on one or more corners
- ▶Vehicle dropping overnight and re-inflating when started
- ▶'Suspension Fault' warning on the dashboard
- ▶Compressor running continuously or making unusual noises
- ▶Ride height not adjusting correctly in different modes
- ▶Air suspension unable to raise for off-road mode
What Causes It?
- ✕Air spring bladder failure — the rubber perishes over time, especially in cold climates
- ✕Air suspension compressor failure — motor and/or compressor head wear
- ✕Valve block solenoid failure — prevents individual corner adjustment
- ✕Height sensor linkage wear or failure
- ✕Air line damage or perished connections
- ✕ECU fault codes causing the system to lock in one position
The Solution
JLRMAN diagnoses air suspension faults using JLR's SDD software, giving us full visibility of all fault codes, live height readings, and component status. We replace air springs (using quality OEM-equivalent or genuine JLR units), compressors (rebuilt or new), valve blocks, and height sensors. After fitting, the system is calibrated using SDD to ensure correct ride height values across all modes.
