Check that both of the electrical connections going to the struts are properly seated. There's one next to the air line, and another connected to the center of the strut. The one on the center of the strut seems to be more prone to bad connectivity than the other one. Not sure what you mean by "shows in the instrument cluster". After that, do the soapy water test on the top of the strut to see if anything is leaking. These cars do not like to be left hanging in the air for any real length of time - even with the suspension turned off. My theory is that doing so causes the o-rings to lose their seal and then start leaking.

 

@shrike071 Whenever I press the raise front button it says on the rightmost display to some effect height chosen. When pressed again something to the effect the front is lowered. Would definitely be a surprise when the button is pressed, the car moves up and down, but nothing shows in the right display, my interpretation...
