For the past couple weeks, I've been getting a "Service Air Suspension Immediately" warning in the first few minutes after startup which disappears in a few seconds. Theres no standing warning lights. Suspension is factory with no mods. Lately it has not let me move higher than Aero height, but it did lower to entry/exit (then wouldnt raise back up). I came back later and the height was back to aero. I pulled the air compressor fuse overnight to see if there was a leak. There was no change in ride height overnight.
I went out of town and no issues after several hours of driving. Then after parking and coming back several hours later the rear was noticeably lower. While driving, the rears were hitting the bump stops and had no dampening. Had to drive back home a couple hours with no rear dampening. Dash still displayed no standing warning lights and still aero height. Front suspension was fine going over speed bumps to test. Back home removing the rear wheels and liner and found the drivers side to have no pressure, while the passenger side still felt firm. Sprayed soapy water everywhere on the folds on both bags underneath the dust cover (where most leaks tend to occur), compressor fittings, accumulator fittings, bag fittings, and could not locate a leak. Compressor still runs and sounds normal and cuts off after a lengthened runtime.
Is it safe to conclude from this that the rear bag is bad and also since 3 of 4 bags are good that the compressor is good?
