Air suspension w211 estate 2006

[Waders]

Hi everyone
I know this probably has be discussed lots before but, I have leveling suspension on the rear and before I start looking at suspension bags is it possible to check the air suspension valve block is not leaking back? Maybe taking off a hose from compressor to block should it leak back to pump? Or would this even work? Many thanks in advance.

The bags have a solenoid valve built into the top on a 211. If it’s sinking it’s definitely the bag. Even if you take the pipe off the bag it’ll stay up

Is that even on the rear ones? Is there anything else that could make it realise air when parked as these suckers are super expensive

Very few problems with the valve block it’s usually the airbags or pump
