My 05' LR3 is sitting on the wheels. I hadn't been to my truck in a few weeks and came up on it sitting so low it's sitting on one of the wheels. I thought maybe it had been some time past and once I would start the engine it would raise back up, but it didn't. The Suspension light is on AND the Adaptive Front Lighting System light... neither of which had been on ever before.

Could it be the battery, for both systems going out? Or is it just coincidence, and it's my Compressor and a fuse for the Adaptive Front Lighting System?

Please help!

 

Questions regarding the Discovery 3/LR3 models should be posted in the LR3 section of the forum. That is where LR3 folks hang out and will be more likely to respond to your posts.

As for your issue, it may very well be the air compressor has gone bad. Or perhaps one or more of your air struts has failed. It is common for the air suspension system to develop problems such as leaks in the struts and compressor failures after several years of use or 100,000+ miles on wear. Get the truck charged up, turn it on and hook up a computer diagnostic device so you can read the air suspension system codes and pin point the problem.
