W211 E320 Airmatic issue I couldn’t figured out
Hello all,
I have been searching for days and couldn’t find any information about the issue I am facing.
The front left air strut is the only one releasing air, even when I lift it with my hand. It hisses with each lift but doesn't leak when untouched. Any increase in level—like accelerating quickly after a green light or making a hard right turn—causes the hissing (air leak)
In test mode, I can fill the front left strut up to 89 PSI, but it hisses if I try to increase the pressure further and then drops back to 89 PSI. When I lift the front of the car with a hydraulic jack, all the pressure in the front left strut discharges, while the front right stays at 75 PSI. I also tried filling the front left while the car was lifted, but it won’t hold even 1 PSI. I checked the level sensors and they work properly. Thanks a lot for answers.

Hmmm. Untouched. Car height stable. No hissing, thus no air leak. Car height increases, hissing, sounds like an air leak. Perhaps a hole is exposed as the rubber bladder unfolds? What do you think?
Replace both front air struts. And use the "Advanced Search" in the upper right. Dozens, if not hundreds of posts on this subject. You might find a very large technical document on the Airmatic system that I posted multiple times. If you find it, download it and study it.
Also, after replacing the front air struts, be sure to recalibrate the air suspension. Did I mention "Advanced Search"?
