Thread: Air suspension playing up

I normally drop my suspension to access height when I get home of a nite, but the last few nights it has not dropped.
When I start it up the next day, the suspension will drop when I move the main controller.
Having just arrived at work and tried to get access height again it will not do it.
Also I've noticed when i pull up at a set of lights the front drops down a fraction and it never used to do that before.
Any suggestions greatly appreciated.
The beast is L322 2003 model.

Check / clean the exhaust valve silencer at the compressor. Mine was dirty and it caused suspension faults, wouldn't lower, etc as it couldn't vent air. Pretty common, or so I read.
