I'm glad you're all sorted now Ann, and are back behind the wheel of a very nicely speced Golf.
I've got the same tyres and find them quite noisey. I don't drive the car that often, but I suppose if I was in it all of the time I'd soon filter it out. Performance is acceptable as it never really gets pushed that hard, and as it does so few miles, I can't really comment on the wear.
Where abouts in the sweep do your wipers click? I found my drivers side one was set a fraction too high and was clipping the rubber at the edge of the windscreen at the top of it's sweep. A quick adjustment of the wiper arm, and the noise stopped. If it is the same as mine, your dealer could fix it in a cpuple of minutes.
