Thanks all. Most grateful. 
Looking at your first picture again, I can see why you're so hacked off. It looks as if someone's been at the bumper with a heat gun 
The thought had crossed my mind ..... and they did a rubbish job!

Went to the VW Service dept to see a black GTi. First they said it was as bad as mine and there was no need to see it! There was some distortion, but nowhere near as bad as mine.
It was in a difficult place for me to take a picture. Will go back later.

Hacked off with VW to say the least.
