W220 s500 03 rear drop after parking within 2 hours
my benz w220 s500 03 drop within about 2 hours in rear left side, I replaced before front suspension with refurbished and until now front can hold for even few days,
airmatic valve replaced many time and finally I cleaned and reassembled from few months ago just last two weeks car droping just rear side, specially left, i expect airmatic valve but before i open for replacement i checked the rear strut copper valve at top of strut, i remove the hose while car in good height that time it drops fast hence air flow from strut fully,
this copper valve is it functioning as one way direction?
or it pass air similar to my case when hose removed?
