I have a 2005 LR3 that displays “Suspension Fault”, after the engine has been started, for about 30seconds and will not allow me to adjust the suspension. If you adjust the suspension immediaty after you start the engine, it will allow it to be adjusted, although the message display says so slow down so suspension can return to normal. Not that I need suspension height all the time, I just want to fix the problem before it causes more problems

 

Need codes. But if its happening after a delay then its could be the compressor or a leak. If the compressor draws too much power, fault. If the reservoir is empty (possible leak) and it powers up to fill it but finds it fills too slowly, then there is a chance of a leak. Codes will give a better answer.

 

I had that situation and I needed a new compressor. Fairly easy fix
