Double bugger. Despite 4 days of penetrating fluid and applying the blow torch I now have the remains of 2 sheard bolts wedge in the uprights. It's official they are stuck fast and not coming out. I now have to firk out £720 to Audi purely for there design flaw and buy 2 new uprights. I don't mind spending money to see an improvement or upgade but this takes the biscuit.
