Range Rover Sport L320 4.4 V8 / 4.2 supercharged V8 petrol: air suspension check

Suspension · Range Rover Sport L320 (2005–13) · 2005–2009

How often: every 15,000 mi or year, whichever comes first. Air springs perish with age; a leak makes the compressor overwork and fail.

Work safely: support the vehicle on axle stands, never a jack alone; let it cool first. Check figures against your workshop manual. You do this work at your own risk.

Parts

Air spring (if leaking)

Tools

Soapy water spray
Diagnostic tool

Step by step

Park overnight on level ground; note any corner that has dropped.
Spray the air springs (folds at the bottom) and pipe joints with soapy water to find leaks.
Read the suspension codes; listen for the compressor running for long periods.
