can be considered as normal but its leaking.
as this cars gets older the value of them often is lower than a genuine Airmatic rebuild so most owners seems to be happy if the car aint on the ground in the morning.
but a rebuilt system won't lower 1cm in a weak it all comes down to cost and how many USD you ar willing to spend.

this leak was lowering the left rear 3cm in 7days over night it was not noted

hmm i already replaced the rear ones few months ago but actually never measured it , im actually suspecting if something is wrong that compressor is letting air out since it was driven with leaky airbag for at least a month and when i turn on the car it doesnt raise anything after it sat for 4 days

on 211 Airmatic ther is valves in each strut so when car is turned off and in sleep the individual valves are closed.
that way only the leaking strut will be affected. but if for some reason the dryer on the compressor is full you cold get water in the system and then anything can happen

To clarify, approximately 30mm of suspension dropping in cold temperatures is within design parameters. You can check for external leaks, no leaks found could be internal valve/solenoid malfunction - see attachments. Also consider compressor rebuild as it concerns moisture: https://mbworld.org/forums/e-class-w...e-rebuild.html
