Air Compressor Hose Not Working

If I screw the air hose into the connection under the passenger seat it no longer puts out any air. It may blow air out for about 1-2 seconds but that's it. It's almost like the air tank is empty. I had a flat tire that I was airing up fine for a couple minutes then it just stopped - I thought maybe it just needed to recharge or something however that was a couple days ago and it still doesn't work today.

My air suspension up/down still works fine. And the dashboard still displays the notification when I screw the hose in.

Any ideas what the issue may be?

I have exactly the same issue.
Its the same hose as the touareg and a quick Google search reveals it's a common problem.
On mine, the section of hose from the tyre to the dial seems ok - if you undo the plastic screw the tyre deflates. As it should do.
I cant work out if it is the section of hose from the car to the dial that has collapsed internally or the valve/dial that is faulty. Have you undone the brass screw to see what happens?

You are probably already aware, but just fyi the ignition needs to be on (engine can be on or off) for the compressor to work. It's thrown me for a loop before, in any case good luck with the diagnosis.
