I'm a new owner of a 2011 Range Rover Supercharged and it's got what sounds like the identical suspension issue as the original poster, Keithr2003. When I park it overnight the front end lowers to bump stops, but not the back end. It started when I went to lower it to access mode one day and it threw a suspension fault. Since then (about 10 days ago) it's thrown occasional suspension faults which clear on restart. Usually the suspension faults are not a problem and the car keeps its normal ride height while driving. But twice it has said "30 mph limit" but then self-cleared that message after a few seconds.
I do have one interesting observation. See if this information helps. I had the car running while waiting for my wife in the post office. I had the car on "max AC" and she was in there about 10 minutes. After about 8 minutes I noticed the front passenger side had lowered considerably while the front drivers side had not lowered as much. It threw a suspension fault. I turned the car off and on, and the car immediately threw another fault (that doesn't usually happen) and wouldn't raise up. I drove it home 2 miles with the lopsided suspension. When I got in the driveway I turned off the car and turned it on again. Immediately the car raised up and self-leveled like it normally does. It was almost as though having the battery drain of the "max a.c." kept the compressor from being able to engage until I had driven it some more and charged up the battery again. So perhaps it is some kind of electrical glitch in our cars. The previous owner had said that he had battery problems some years ago and I might want to look into that again.
If anybody has insight on this problem let me know. Otherwise, I'm taking it to the Indy mechanic next Monday.
Thanks,
RJ
