Please do I’m having the exact same issue and your description is exactly as I’ve been describing ours. I plan to strip ours down tomorrow to see what can be found.

So they spent a good amount of time diagnosing the issue and couldn’t find a cause as there was no leak (lots of pressure testing, etc) and no errors. I’ve been advised to try vw for an ecu update to see if this solves it. I’m currently in discussions with my local vw van centre as they want to change £250 but I’m not willing to part with that for something that could be a vw fault. I’ll keep you updated but no definite answer yet frustratingly
I will send you money if you manage to work this out as having the same problem. Done everything you have done including replacing some of the charge cooler pipes.
I've bought a dictaphone with external mic which I'm going to move around the engine bay to see if I can identify where it is loudest.
Thanks mate, absolute money pits at times these vans.
Just to further reinforce this point was having a good look under the van tonight at various hoses and my power steering pump is pissing fluid...
How did you get on with this?
I'm currently in discussions with VW as they won't do a software refresh/update if it's not 'needed' and because there are no errors showing they don't think there's a problem. Very annoying!
