Have a 2006 XJ8 that has been performing flawlessly in the ten or so years that I have had it. Recently it seemed to raise/lower the suspension less and less. Today it did not do anything. So…first question does the air suspension have it’s own compressor ? If so, where is it ? The regular “in car” air con is working fine. The reservoir and valve block under spare wheel in trunk/boot has no obvious faults. Any and all suggestions/comments would be welcome on how to proceed from here.
Thanking you all in advance
