Hi Guys, After much pain and sorrow...........................I think I have eventually resolved the problem of my RRS lowering overnight. Some of you had came back with suggestions, which were much appreciated. Most people suggested that the height sensors were faulty. MaCrae and Dick Inverness have been working on it and after 6, yes six sensors, one air bag, two valves, they decided to replace the compressor. At last, it appears to stay up all night........ My thanks to the engineers there as the leak was very small but sooooo annoying as the RRS sport looked poorly as it sunk, mostly at the rear passenger side. Thought i would just share my good news. Steve

nice one, i had a nightmare with my passenger rear side leaning - in the end it was the air bag itself
