Friends,
When I switch off my car 221 S500 then just fiew seconds I hear a sound (shhhhhh) like relief valve open to discharge excess air, that sound came from front right side same side of Airmatic compressor.
Second thing if I keep my car for two three days parking car's level goes down by half inch and when switch on immediately the compressor start and to raise the level.
Can some body help me to diagnose these two problems

These are symptoms of a leaking system .. you have to identify which strut is leaking .. what you can do is raise the level to max height then try to listen at each wheel for a hissing sound .. if u cldnt identify it then you should monitor it and see which side is getting lower first ...

Star would identify the problem . If it didnt register a fault code you can go with the guided diagnosis to identify which part of the system is leaking ... but i think the above procedure would be enough .. gd luck

Thanks Mohd,
The sound from right front side
In this case what I have to
Is it normal to keep it as it is or it might go to worst and I have to resolve it ASAP
In such case is it strut damage and need replaced or can be repair

You should change it now .. this leak means longer airmatic compressor operation .. it might burn it up with time
