Good evening,
I have a problem with the air suspension on my 2002 L322 Range Rover.
The suspension has always been a little slow to raise into the different height settings, but has never caused any issues.
A few times over the past few months it has been throwing up the Air susp inac warning on dash. Plugged in my Hawkeye Diagnostic, the fault was always "Reservoir pressure static when filling" the air susp light is illuminated on the dash with this fault but can't change height setting, cleared the fault and has been fine for a while until it throws the fault again.
Now, since this cold weather spell has greeted us, it's constantly throwing up fault codes either "Reservoir pressure static when filling" or logs a separate fault of "Reservoir pressure drops when filling" and completely shuts down the air susp system (loose all lights on dash) either or fault appears at one time, not both.
Now, looking at Live Data, the reservoir pressure goes upto around 11.7bar and then the compressor cuts out and it retains this pressure.
There are no air leaks in the system. The front struts/bags are relatively new (1year)
I'm thinking either;
1) Compressor is knackered (no idea how old it is)
2) pressure sensor is playing up
Or
3) a faulty valve allowing the air to pass?
Before I spend/waste any money throwing new parts at it, any thoughts/ideas from anyone?
For me to test the compressor, if I release all the air out of the system, how long should it take to raise to the 'normal' ride height and the compressor to build up the pressure in the reservoir upto 11.5Bar+?
Many Thanks for your help in advance.
