Gents have been looking through the workshop manual to find out which sensor and where it is situated gives the information to the ecu that the car is grounded and so sends it to extended mode and can't find anything anyone any ideas\

Yes think you are right from what I have read which doesn't help me afraid but still good to know |

Super extended mode is activated by the driver whilst in extended mode by holding the brake pedal pressed then pressing the raise switch. |

Hi Sandyt, mine used to do that as well and regularly give me suspension fault messages. I am currently under test to cure it which so far is going well.

I believe there is also a "knock" sensor, so if your underbody hits something the suspension reacts. .

No knock sensor for the suspension which wouldn't be of any use on loose gravel roads anyway. The static height sensor signals when the vehicle is meant to be changing height is the indicator. |

Well going to work through it tomorrow and see what I find but as my poor old bus is 10 yrs old and nearly 150k on the clock may just replace the back bags (fronts done a couple of years ago and a new pump AMK ) and replace all 4 height sensors
