W211 suspension leak rear right

When I start car raises to normal height, then about 20 min after I hear a lot of air coming from rear left. I can’t determine from where? I’m trying soapy water test...
no warning lights come on🤷*♂️ Ran veepeak and doesn’t show codes, may not read suspension.
If hear the “hiss” loud from rear driver side then is it air bag? Only error message from dash is front right airbag deactivated, then soon after becomes activated again.
I jacked up front passenger side of car and left jacked up for three days. Ironically rear opposite side lowered.
Can it be from that? Putting too much pressure on side and messing up sensor or something? The w211 model sucks👎 Always an issue. I just had it fixed

I had the same issue with the hissing and no luck in finding the leak or anything. Had to replace the shock, got lucky and found one online for $250 used. Soon after that, I had a wire corroded to my airpump under the bumper, and I had to solder the bare wires to the pump to get it working properly.

Hope I helped!
