Land Rover Repair: need help/advise, isolation valve, airspring

Question
Hi, I own '01 4.6 HSE, and it's been a week now that over night the passenger front side went all the way down (sitting on the bump stop) but it will go back to normal height when I start the engine, so far. Is this an indication of a bad air spring or there is leaking somewhere on the line? No warning light on the dashboard. Any advise and suggestion would be greatly appreciated.
Any info or experience on Arnotts airspring?

Regards,

Arif


Answer
You have a leak somewhere, either in the spring, the line, or the isolation valve for that corner.

It is common for the battery acid to leak onto the airline for the RF spring and cause the line to leak.  If you leave it go too long you will get a fault.

I am a distributor for Arnott's, there springs are hard to fault, carry a lifetime warranty and are less expensive than OEM-hard to beat them..
