So after going through the Range Rover I just bought decided there was too much work and sold it today. I'm looking at a 1997, its only had one owner and engine was all re-sealed. Only thing he has told me is the Air suspension will go slowly down after a few weeks, is this normal, it has never had any work done and has only been highway driven. It goes up really fast so I'm assuming the compressor is good, I've sprayed the bags wth soap and water and they dont have leaks that I can see. Does these systems always need changing? Is this normal? Thanks

 

When the truck starts, the suspension does not lift, drive around the block and you can raise it, the truck had been sitting for about a month, I'm assuming this is not normal, can anyone give me advice?

 

There are 26 pages on this in the RAVE shop manual. It is a complex system, and even tries to adjust height once in a while when truck is off.

Saw this warning:


Air leaks

 

The compressor should achieve 140 psi in approximately 7 min
If you open the door (inhibiting the ride height) and start the truck, you can time how long it takes to cycle from on to off. If the compressor keeps running but the vehicle does rise there is a good chance you'll need a compressor.
The air suspension will work with less than full system pressure. It just wont work properly.
The tank should hold presssure overnight if the system is leak free, and the suspension should adjust up after you start the truck.
The suspension system is designed so that it will wake up and self level itself to the lowest corner every few hours.
If the system is leak free the height change will be minimal.
Soapy water is your friend for finding leaks air springs usually leak faster at standard ride height or low profile
EAS faults.. One hard fault defaults EAS to standard ride height and inhibits height change. Two hard faults put you on the bumps...
Find yourself an eas buddy to clear codes or download the eas unlock suite from www.rswsolutions.com and you'll be an air suspension pro in no time.

 

Thanks a bunch very good information, im buying it so Ill let you know how it goes!
