L322 Air ride inactive any idea why?

So I had an "air susp inactive" message on the dash.
Diagnostic says "compressor temp static when compressor is active"
Anyone know what this actually means?
I cleared the code and it's been ok for a few days but happened again today,
Says "reservoir low pressure when filled" this time. Code cleared and working again now but only a matter of time I'd say

You compressors not making enough air and shutting down ,,when its running its over heating .....Think edd china had a similar problem on wheeler dealers,,Have a look..

Air pressure switch maybe? Any leaks on the block...

Is it easy enough to rebuild the pumps? There are kits available on eBay for less than £15 but are they any good??

From what I've read on here, there are a few different pumps on the l322, some can be rebuilt, others are scrap.
Only what I've read though so treat with a pinch of salt.
Just make sure you get the right rebuild kit and/or pump depending which route you take.

So I rebuilt the compressor today, really easy and really cheap. All working well again, Happy days
