First Post so I apologise if this is going over old ground but I have looked at previous posts and cannot find the info I need.'

Right, m long story short I have had a problem with the suspension which would sink overnight and sometimes on a journey.
I have just replaced the bags, and using the switches in the boot managed to empty the old bags and replace relatively easy. I have now finished and have pressed the OFF button to reactivate the suspension and it will not reactivate.
So to light is remaining ON on the deactivation switch and the UP/DOWN switch will not work.

My question is does anyone know what parameters must be met to reactivate the suspension? ie does the car need to be at the uppermost or lowest position to reactivate? is there something i'm not doing correctly? I'm Stuck!

For information the car knows when it is at uppermost/lowest positions as it give me the different picture on the dash with the 5mph warning.

Is it likely a dodgy/tempramental compressor on top of the bags?
How can i test the compressor?

Any other potential reasons why this would happen?

Any help would be much appreciated as this is my other halfs daily driver and with a 4 year old and a 2 year old she is desperate to get her wheels back.

Thanks in advance.
