I have a 2013 S550 and I'm experiencing an issue where the right side keeps sagging. The suspension compressor stopped working, so I replaced it. However, the new compressor still doesn't turn on. I've checked the relays and confirmed there's power. My question is: if the valve block is malfunctioning, could it prevent the compressor from turning on at all, or should the compressor still activate regardless of the valve block's status? Essentially, I want to know if a faulty valve block can stop the compressor from even starting up.

Sorry to hear about that. So, to the question you asked. The valve block cannot stop the compressor from starting. That will be either electrical issue, a fuse or a relay having a problem. You should have it checked by a mechanic.

Hi 👋🏼..What was your symptoms that you went changed the valve block ? Thank you

[@all-about-cars-basics]

The car kept sitting down especially when parked for some time. And every time the car was started, the pump would always run to compensate the lost suspension air.

@@all-about-cars-basics oh ok , I tested mines by having it lifted up (ml63) and came back 5 days later still raised up as I left it , however it rides stiff as stuck on sport mode ( sport or sports plus is not engaged ) any thought ? Valve? Or pump ?

@@BiLoSellHigh Ooh okay. that means your problem is not with the air suspension system. But it is with the damping system. Maybe one or more strut damper is gone bad. To understand it better read the explanation on w220.wiki/Airmatic#Adaptive_Damping_System_(ADS_II)
Good luck. And let me know how it goes.
