I have tried to fit the Audi made aluminium roof bars bought for my C6 model on to my C7 model, and have found the whilst the rear bar dimensionally fits " just", the front bar is set too wide, by around 30mm. I am supposing that I'm just going to have to eBay the existing ones and repurchase new - but before I do I just thought I'd ask the community if anyone has come across this annoyance and if anyone has discovered a solution the doesn't cost £200+ ??
