hi
one of my height sensors broke and i didnt know so i recalibrated the suspension as i was doing this the rear left was so hight i thought it was going to burst so i pull the plug on my laptop as i couldnt abort
the compressor would have keep pumping the bag up because the height sensor arm had been disconnected
now the back air bags are at the height that isnt right
im getting new sensors in a few days can the bags be deflated manually ?
i think i may need a new module too as i cant seem to communicate with it since i disconnected during a calibration
any help will be apricated

 

Had 460mm on the back right side, super cold that day,
superstiff too. Like jumping
I put two secondhand heightsensors on it working ok. Then
ordered new ones from jaguar without the bracket to the body. Front ones are fair price( 90€) a piece they come with the short arm.
The rear ones are more expensive AND COMING WITH THE LONG ARM.(163€)
SINCE the arms on the old one in the back were still in good shape I changed them over to the front ones I bought
It is easier on a warm day lying in the sun, put a thin screwdriver into the outer plastic (that is keeping the ring in place) to get underneath the outer ring some penetrating oil then push them off with a plier.
if the plastic rings already have cracks then get complete second hand or just new one.
level out with sdd
386mm front
373 back

 

To deflete manually open up the trunk take the lower carpet out . 2 torx . Then the sides . You'll get to the airstruts . The 4mm airhose screw with the squeezing olive inside can be unscrewed competely the air is coming out that way BUT First put a jack stand under neath the car on that place height 340mm center to arc.
just don't play around with that screw and olive (that on breaks easely.

 

this is the front height sensor 82€
Without bracket
