Sorry guys, but had to start sorting out for the trip at the weekend and missed out on the thread. Gary does lift on the wishbones with the car doors shut and the keys out of the ignition. So far 3 cars left in normal running height mode have displayed an error and took a bit of fiddling to let down the suspension. Haven't got a clue why, but it is becoming the format now. Must try with indicators flashing next time. Had it just been my car I would not have mentioned it as it had the steering ring defect, which for some reason messed up the suspension, how does that work then?

might sound a bit daft, but....
try disconnecting the battery - once you've took the keys out and waited the requisite 2 minutes - you only need to disconnect the -ve
the only thing that needs resetting is the clock

I think there's your explanation....lifting on the wishbones makes the suspension think that it is "stuck". As a result, the system freezes the height. That's my theory, and I am sticking to it!

Probably because of the interlinkage of a number of vehicle systems - that's why diagnosing faults is clearly so difficult.

Lifting on the wishbones should keep the load on the suspension, thereby preventing the suspension dropping... BN, are you sure it was supported on the wishbones and not on the chassis legs or wishbone mountings? were the wheels hanging or did they appear to be in their normal position within the wheelarch?

And you'll loose all trip and mpg info The End

I think that the act of lifting on the wishbones, because of the multi-articulation of the suspension, is actually signalling to the control system that the suspension is frozen (read stuck); the result is that the system freezes at that height until it is reset.
Of course, there are plenty of places that you place a trolley jack to lift the vehicle, but remember that air suspension vehicles are jacked from the chassis, not the suspension arms. Go and try it both ways, and watch what happens to the height sensor using both methods.......

Definately on the wishbones everytime. I think Slimer is going up on Friday, so he can try his but not tell Gary about the problem, just ask to have a look underneath or something?

Ah but I'm not having the wheels fitted, just the tyres to them.
But I do have what I think is a slightly dodgy valve on the OSF wheel so I could get Gary to take the wheel off and fit a new valve The End

Si, thats what I suggested, silly person. Or as TFC would have put it 'stupid boy Pike'

So the mystery deepens. If the car is lifted on the ramp and the front wheels are lifted by the wishbones, the top of the wheels go outwards, i.e the wheels are pigeon toed slightly.
OK guys, could that be the answer, have we found something?

Could be the 'TILT' sensor. The alarm has a device that tells the system that the car is moving, but the wheels aren't, i.e been jacked up, some scroat about to nick the wheels, so maybe the alarm electronics are interfering with the suspension?
