My suspension had started to get very slow to respond now today when the compressor kicked in it drained the reservoir down to 0.3 bar and message on error code pressure drop on memory.
Before this pressure was constant at 9 bar and occasionally gave pressure constant error.
Compressor has new piston ring and was holding a constant 9 bar until today.

Either a leak in the reservoir, or bite the bullet and get a new compressor (I fought my old compressor for months, trying all kind of things, new compressor sorted all the problems) You can get new compressors on eBay without all the gubbins / turtle shell and wire them up yourself, save @ £100 or more. .
Experience is the only genuine knowledge, but as time passes, I have forgotten more than I can remember
