Suspension Issue

[Guest hedgehog]

Have you tried to reset the suspension? At the front of your engine you will see what looks like a sphere well this is your pump at the side you will see a bolt this needs to be undone 12mm spanner (but undo ONLY A 1/4 turn) this will let all the pressure out of the system watch out as the car will drop right down to the floor when it stops hissing out air tighten it up start the car put the suspension to normal ride height let it go up and give it a drive up the road & see if that works (DON'T DRIVE UNTILL THE RED LIGHT HAS GONE OUT FIRST AS YOU WILL HAVE NO BRAKES!!!!!)

 

 

I have tried the above, but the rear suspension is still vertually rigid. Was ok until car was left suspended overnight. You dont say which position the suspension has to be in when the 12mm bolt is loosened. After undoing this bolt I heard a short HISS but the car did not drop as descibed. Any ideas would be a help.
