Forum DIYXoutpost.com (X5 E53 Forum)Difficulty: MediumTime: ~1 h (compressor rebuild)written for E53 / E39

Fixing your Air Suspension. ↗

Owner guide to the 'Self Leveling Suspension Inactive' fault. Clear the code with a scanner so the compressor runs again, then check the likely culprits in order: leaking air bags, a worn compressor (rebuild kits with a new piston ring and seals take about an hour), the ECU, and the reservoir and fittings (soapy-water leak test).

Tools mentioned: Scan tool that reads EHC faults, 1/4 in socket set, Torx bits

Written on an X5 4.8is (two-axle system); compressor advice applies to the rear-only system too.
