Any ideas why this happens.
I have checked all struts back and front and the car is still at the same height in the morning.

best be getting a diagnostic tool onto it.

First i would take the little brass breather off the exhaust port of the compressor, run it a few times and see if the fault will come back (they block over time and it takes the air too long to escape and logs a fault, technical bulletin is out saying to either replace or drill a hole in it)
