Aha, thank you, as for being brave..nah but never actually having driven any Citroen except a Visa way back in the day this will be the first i have had experience with :), do you have any idea how much a new compressor and or air bags would be, A back story of why this car was needed is I am severely Disabled and as such have to use a class 2 Powered Wheelchair, having the option to lower the rear in order to ease the loading and unloading of the chair (125kg) would be a godsend and allow me to have a certain degree of freedom so i would really need to keep the current setup if that is feasible, the vehicle itself was got for a LOT less than it should have been so I am willing to spend some money on her, when you say a fault on the compressor do you mean a sensor not relaying height as is should and thereby causing the compressor to operate all the time ??.
