Right people,
Recently iv had this weird and concerning fault light coming on my dash,
Be great if someone could shed some light on this,

Everytime i pressed the suspension button, either to go into off-road height, or access height, after the compressors done urs job, the suspension fault light comes on with a bong noise, its stays on unless the switch the car off & back on again.

Car goes into all modes, up or down without any problems.
Anyone know what this could be? Why it always flags this up each time i press the suspension button.

Thanks in advance
