So I have a 2005 lr3 Land Rover and I keep getting a suspension fault message. Sometimes the vehicle won't adjust it's height and sometimes it does. Sometimes it will lift the front driver side a little more than the passenger. And sometimes I get Suspension fault do not exceed 30 MPG. I also get a parking break fault messege (could be a different problem though, unless it's a battery issue?)

Maybe it's an air leak? I can hear a little air escaping on the driver side. But not sure where it is coming from.
Possible unrelated notes: I also can't get the sunroofs to open, the stereo is stuck on phone mode and the trunk door won't open.

I know that's a lot of problems but if by chance any of them are linked maybe y'all can help me diagnose what's going on???
