Range Rover air suspension

Disclaimer - please read

We have reports of air suspension problems and difficulties with diagnosing problems (or getting the suspension up) without the dealer HP notebook tools. It appears some owners are retro-fitting conventional coil spring suspension which may not be as costly or difficult as it seems at first sight - Anyone out there want to contribute a single page summary of procedures for me to publish?

A UK company, Scorpion Racing (London NW) can retro fit coils springs in one day for around UK600 plus VAT, or supply a DIY Kit for UK400 plus VAT. Contact Colin on 0207 485 5581 or email colin@scorpion-racing.co.uk If you have any comments on this service please email me.

As always we are looking into practical solutions and we hope this temporary page helps. Helpful practical observations on air suspension by David Burton can be viewed here. Mark Chandler has also sent in useful information on fooling the air suspension so it can be pumped up and the vehicle kept in use until the fault is rectified. Click here to view his email. Peter Barnes has also identified potential overinflation dangers from the a air suspension delay relay whilst carrying out these procedures, please click here to view his email.
PLEASE NOTE: DO NOT UNDERTAKE THESE PROCEDURES UNLESS YOU ARE SURE OF YOUR COMPETENCE. IF IN DOUBT, PLEASE BE SAFE, PRINT THESE PAGES AND TAKE VEHICLE TO SPECIALIST.

Problems seem to originate when a suspension component failure or maintenance work triggers an ECU fault code - It seems that any fault code will cause the system to vent and lower onto its buffers - 'limp home' mode, literally!! - Not helpful if you're stuck in the bush hundreds of miles from a dealer.

Fault codes can apparently be triggered by such things as changing shock absorbers or alternator failure - FAULTS CAN TRIGGER WITH IGNITION SWITCHED OFF!! - so it may be necessary to disconnect battery before working on suspension.

If a fault code is triggered, the air suspension control buttons will be permanently lit (as opposed to lighting up and going out when engine is started) and the system cannot be restored until the fault code is reset by dealer HP notebook.

If a fault code is not triggered, but suspension will not pump up (and no leaks), problem could a seized compressor - try hitting compressor body with a SOFT hammer. This has a reasonable success rate but check fuses and electrical 1st!!

We also have one report of fault codes being triggered by defective battery earth cable/connection to body - the fault went away when cable renewed. Please email if this is your experience.

We understand fault codes survive ECU disconnection so it should be possible to airmail ECU to a dealer who can (using stock vehicle) read fault code(s), reset ECU and airmail it back to you together with any suspect part identified by fault code. If you've done this successfully please email.
