Changed the air compressor piston ring. When I attempted to raise the suspension heard a bit of a bang and found out the offside bag had broken its bottom mount off. Bought a new bag and its again jumped out of its mounting including ripping off the top clips. It's now fully inflated. The height sensors are relatively new (genuine land rover). Any suggestions? I don't want to have to replace the bag again because I'm struggling for length of the air line.
