W211 E63 lowers all the way down when car is off
What do i need to check to see why my W211 E63 lowers all the way down when car is off. I do not hear any leaks. As soon as I hit the unlock button the car rises. it's not one sided, it just the whole front is down.

I do not hear any leaks-just because you don't hear them, doesn't mean they aren't there. If it's just the front that lowers down i would assume a strut or two is leaking.

You could use the soapy water experiment however that isn't exactly precise if something internally is leaking. I assume you have a good pump right? It is possible that 1 bad strut could cause the whole system to sag. If your airmatic control unit senses a implausible strut it will go into limp mode and or compensate for that 1 bad strut. There are a million threads on this topic. The search bar or a shop with sds is your best bet. Everything from us is speculation ya know? Good luck!

Some things to check short of pulling codes - pressure line connections (soapy solution) to both struts and compressor valve; condition of struts; level sensors inclusive of wiring, part # 0105427717 "viewed" here http://www.usedautopartsyouneed.com/...27717-695.html

Since each bag is having separate valve - having all of them failing at the same time is very remote possibility.
I would rather suspect a computer glitch.
That brings scanning to mind.
With such big leaks your compressor would have to run almost all the time, so monitoring the compressor work would answer some questions.
When was the last time you serviced the compressor filter and dryer?

Agreed, but this particular failure might be weather or road condition related possibly affecting both sides - simple/quick inspection before pulling codes.
