Land Rover Range Rover: Air Suspension Compressor Overheating & Failure

The EAS compressor is forced to cycle excessively when air escapes from perished rubber air spring bags, cracked interconnecting pipework, or leaking valve block solenoids. Sustained thermal stress destroys the internal piston diaphragm, burns the motor windings, and trips the thermal cutout permanently. The rubber air bags fail independently from UV degradation and age-related cracking, which then forces the compressor to run continuously until it burns out. This cascade failure is the single most common fault on all L322 variants regardless of engine.

• Vehicle sitting low on one or more corners at rest
• Compressor running continuously or not at all
• Air suspension fault warning on instrument cluster
• Vehicle fails to raise from park/access height
• Audible hissing from wheel arch area indicating air leak
• System defaults to lowest height and will not rise

1. 1

   Check all four corner heights at rest with engine off for 30 minutes.

2. 2

   Listen for compressor cycling frequency.

3. 3

   Inspect rubber bag surfaces for surface cracking, perishing, or collapse at the lower bead.

4. 4

   Check nylon air lines under the vehicle for chafe or rodent damage.

5. 5

   Request live EAS height sensor data via diagnostic tool to identify the leaking corner.

Parts involved: Air suspension strut.

$700 to $5,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Has the air suspension compressor, bags, or pipework been replaced?”
• “Does the vehicle raise and lower correctly through all Terrain Response height settings?”
• “Has any air suspension fault code ever been present on the dashboard?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
