corner valves

Hi all,

I would like to know how corner valves operate, i.e when should they open/close.

Is there a manual/article with this kind of info?

They open when the suspension height needs adjusting.

Either to raise or lower the car depending on the height sensor input of that corner and the overall height needed of the car

so i guess that if the car is in normal height and you are driving, they should remain closed, Since you do not choose off-road height or access mode to cause them to open in order to change the ride height.

Yeah they should be closed most of the time.

There is a cross over valve. This maybe open to connect left and right.

i have noticed that the front corner valves stay closed all the time while driving in normal height, whereas the rear ones open occasionaly for a few seconds. would this imply that there is a problem in the rear end or at the front end? (valve block issue probably since i get c112f and c1130 suspension faults . visual inspection showed no leaks whatsoever.

It could indicate a leak at the rear yes.

I think you would want other evidence though.

I have sprayed the airspings and they look fine. What else would you check? The car drops overnight but will not drop if i remove fuse 26.
