Air suspension fault

9075 Views 32 Replies 12 Participants Last post by  Roo
My air suspension has now developed a fault. there's no way its ending up on coils(!) so I need to find out what's wrong. The symptoms: Start the RR, air suspension rises to middle setting. Followed by the high ride height warning lamp on the dash and the high ride height & low ride height button flashing repeatedly for a few seconds then going to a solid state. At higher speeds the system remains at middle height and the system isn't adjustable by the usual methods. Is there a way to diagnose the fault via reading codes? I have performed this task for an ABS fault but never for air suspension. Any help would be gratefully received!

It sounds like a 'soft fault' otherwise it would sink to the bump stops and stay there :think:

You'll need some diagnostic gear, at the very least a cable and the free software; if you can get it to work for you! I went the Blackbox solutions route and had no problems, but then that isn't free :wink:

Hi Andrew,

Sorry, it's been a while since I last ordered parts for a Rangie :lol: I meant to put Rimmer Brothers, here's the link:

They stock all sorts of bits for your air suspension ( http://www.rimmerbros.co.uk/Item--i-GRID009626 )
