Brief update: was with the dealers this morning for about 2 hrs

Basically we went out in another Golf R they had on site and it had no noise whatsoever, then into my car where the noise could be heard straight away.
Back inside where the service guy tried to explain that he has seen a few cars like this and is perfectly normal and acceptable, which my reply was, if it was normal then every car would do it and IMO is not acceptable.
Anyway got chatting to the dealer manager and he said every new car is different and they are all going to have abnormal sounds of some description

but he understands I'm rather fussy and needs it put right. So next week he is contacting VW to log my complaint and ask for a fix to be issued, but can't promise anything.
I must mention that I have no issues with my dealer. They have been more than helpful and their customer service is first class, I guess they can only go on what VW advise them to do.
So we shall see what they come up with this week and I will let everyone know.
