My L322 Range Rover 2003 has developed an air suspension fault. No fault shows in the display but the lights in the centre console regarding ride height are not on. Air suspension is not working. Any suggestions please ? Thanks.

First try a battery disconnection procedure to see if that clear any soft or hard faults (see wiki)

If that doesn't work then you will need a diagnostic tool that can read LR air suspension codes (e.g. IID Tool) in order to read the faults and clear them.

You can do a visual check under the car to look at the height sensors and wiring, and also for any visible holes in the air bags.

Most likely suspects - in this order:

Height sensors
Air bags
Compressor
Reservoir
Valve Blocks & piping
ECU .

I would consider buying one of these eas/abs reset tools. Very useful piece of kit.
