One fundamental point is being overlooked: there is no fault with the suspension for VW to fix.
Yes, there is an immediately noticeable noise over bumps on the multi link suspension, and it's acceptability is a matter of personal opinion.
However, now that I know nothing is at fault with my particular car, then I don't worry, as I am happy nothing is going to fall off.
I don't even contemplate trundling off to the dealer to moan about it.
Some manufacturers' models have excessive road, engine or wind noise. But if it's the same with every car made, then there may be a design flaw, but no fault.
In the interest of maintaining customer loyalty, I'm sure VW are beavering away, ensuring it doesn't occur on future models - and some poor sod has got a right rollicking over it!!
