Whoah!!!!!!!! Holy Hell that's expensive. personally, if there was so much wrong with it that really did need changing, then I'd go to a specialist/ independent VW service centre to get it done. They'd most likely look after you whereas the dealer would screw you for every cent you got. P.S. I'm very skeptical that it takes a whole hour to change the brake pads (I've done other cars in half an hour or less and that's without a hoist). All the best mate.
