Wondering if anyone else has experienced this or has any ideas what the problem might be.

Recently the car has started playing up.
Driving along the air con system will just switch itself off for no reason. In addition to this the suspension control panel on the centre console, which indicates the ride height, goes out and the message centre displays a fault with the suspension, telling me the car is locked in whatever height it is in at the time - usually Normal.
Had the car back to the dealers upteen times no but still no joy


Thanks
