Well, all this makes for a bit of shocking reading...
I have had my Superb Estate (SE 2.0 Diesel) for just over a year now and have had no issues apart from a slightly annoying rattle that I can't seem to pin down (it moves!), other than that it shifts (Auto 170bhp) like a rocket in Sports mode, the build and finish is damn good, loads of space for everybody - SD card tends to jump tracks but it may be down to the card as it only happens on one of my cards - the other 2 are fine.
Stuff in the glovebox tends to rattle if you are not careful so thinking of lining it with foam to deaden the rattle, other than that I am very happy with it - guess I must have got a good un' from what I have been reading here...
