Airmatic drops overnight but raises when I unlock the doors.

Dear friends,

I've read posts and the W220 encyclopedia and studied the symptoms.

I have a 2002 Mercedes W220 S430.

1. Front struts are new
2. Changed the relays
3. Compressor works the way it should. It will turn off when height is reached.
4. The struts function correctly.

When I park for 24 hours all four struts lower to the wheel wells and when I unlock they raise up. Is this normal?

By reading the posts, My understanding is that I may have a faulty valve block.

Is my assumption correct?

Thanks for the input in advance.

This car needs professional diagnostics, there appears to be a link to the central locking system that should not be there. Very confusing.
