2020 S560 (W222) Airmatic Compressor Cycling Every 10-15 Minutes in City Driving – No
Hey everyone,
I have a 2020 S560 with the factory AIRMATIC suspension (W222 facelift). I’ve been monitoring the compressor behavior and would like to hear if anyone has experienced something similar.
What I’m seeing:
• Brief compressor run (normal) right after starting the engine.
• Another short run when I start driving.
• Then, while driving in the city (bumpy roads, speed tables/bumps, frequent stops and goes), the compressor kicks on roughly every 10–15 minutes, often noticeable at stops. Each run is fairly short.
The car does not sag noticeably overnight or after sitting for many hours. Ride height stays stable when measured in the morning (no more than normal thermal change). No dashboard warnings, no “Airmatic malfunction,” and the car rides and levels perfectly otherwise.
From what I understand of the official system description, the central reservoir should handle most small corrections in city driving, so the compressor is supposed to stay mostly intermittent and not cycle this regularly.
Has anyone on a similar 2018–2020 W222 S-Class (S560, S550, etc.) seen this pattern?
• Did it turn out to be a very slow leak that Xentry/Star could isolate (even without visible sag)?
• Height sensor drift or wiring issue?
• Valve block internal leak?
• Or something else that showed up on diagnostics?
I’m trying to avoid jumping straight to a shop if it’s a known benign behavior, but I also don’t want to overwork the compressor long-term. Any experiences, Xentry findings, or advice from W222 owners would be greatly appreciated!
Thanks in advance!

Maybach S560 2019
Encountering the same
Greetings
I am encountering similar behavior on my 2019 S560 Maybach. I think it is due to leak somewhere!
I did not check or find-out..
