Removing / Replacing Air Struts

Hey folks,

One of my air struts has noisy valves that I can hear with the windows down, and it drives me nuts. The strut functions fine, but just makes a lot of loud "pfft" air noises over bumps....so I bought a replacement strut to swap in. (I'm aware this is normal, but this particular strut is much much louder than normal).

The swap process is easy, but on all my other air suspension cars I've had the software to depressurize the system before starting work.

Obviously I don't have Toolbox, so what's the safest method for depressurizing a single strut to remove it? Just slowly release the air line fitting and let it bleed out while supported by a jack and in jack mode?

Too bad the struts aren’t straight outta the Merc parts bin. If they were we could short the connector on each strut to open the valve.
Wonder if you can purge via the disti block under the frunk?

I figured it out today. There’s no purge valve, but the air fitting on the strut can be backed out slowly - when you hear air, just stop and let it bleed down. Only takes about 2 minutes, there’s not much air in there.
