I never had the remote lowering but must say I won't miss the air suspension the handling of the discovery is now vastly improved now converted over to coil
I've read your post I've checked relays fuses etc I now think that when I was at tyre place Saturday morning they have caught something when they jacked up discovery
The problem is the air suspension was working fine even with the central locking issues the problem with the suspension started after I had new tyres fitted on Saturday morning
In my 32 years of driving I've driven landrovers all my life and have read hand book and believe me it's doing all the opposite of what it says in the book so I know there is something wrong with air suspension
I'm sitting in it right now all lights working normally pulled fuse from under steering and that had not blown now going to look under bonnet and don't know any one with a nanocom
