Well on Saturday i dropped off my van for its first service at a VW van centre in the southwest, reported to them prior to dropping off the van that the windscreen was leaking and that the rear brakes had been grinding for the last few months. Then today they called me to say they were keeping the van tomorrow as well so auto windscreens could remove it to investigate and then the bombshell. YOUR REAR DISCS ARE CORRODED and need replacing. Under warranty I asked? NO they said.But my van has only covered 18500miles I exclaimed, sorry not under warranty he said. Do you think that's acceptable on a £32000 van I asked and what other vehicle has corroded discs at 18500 miles from new I asked? No reply then It's because it's outside he said.. I was flabbergasted and instructed him not to touch the brakes as I would be taking up the issue with VW UK. We will send you the video, he said. Good said I, I can use it as evidence. Sorry he said not covered on warranty.. Surely 18500 from new I should not have corroded discs? Has anyone else ever experienced this? Can anyone offer any advice/contact emails etc either for VW UK or higher up the VW food chain or anyone else of relevance? Thanks in advance guys
