I parked my 2007 LR3 for about three weeks in the garage and when I came back the suspension fault was lit in red. All special programs off it said. It was working just fine before I parked it. It has about 90k miles on it. I do not hear the compressor kicking on when I start and the suspension is completely down. Im on a budget at the moment so I'm a little afraid to take in the shop. Any idea what this is?
