Q7 Air suspension dash warning

[RaymyM]

Recently started getting a yellow dash warning on my Q7 4M related to the air suspension. Car doesn’t seem to be sagging or anything and drives fine but I’ve got the following codes with VCDS. Is the problem as obvious as it reads, air leak somewhere?

Back to basics mate, spray bottle with water & fairy liquids see if you see any bubbles.

That'll give me something to do this bank holiday Cheers

So now I'm wanting to get a look at the compressor and valves, the heart of the air suspension. Any 'How-to' or post you recommend?

Anyone? Very little info around on Q7's, particularly their air suspension :-s
7zap only seems to have info on the Mk1.
