Its been mostly a year i've been trying to repair it.

the rear is completely fine.

For the wrong is a whole another story.

I have changed the air suspension balloon, fuse and air compressor but still nothing. it still says suspension level inactive and still leaking.

I am considering to change the whole front suspension and replace it with Aerosus ones. Should I also change the self leveling sensor?

Just wondering if there is anything else to check before going this route.
