Has anyone experienced problems with the Quattro gearbox on the A4 3.0 Quattro? I have the Cabriolet and find that the gears crunch - especially when changing between 1st and 2nd. Audi seem to be aware of a problem when the gearbox is cold, but I find the problem doesnt go away when it warms up. (It is definitely much worse when cold). Anyone have an A4 3.0 Quattro Sport Cabrio without any gearbox problems at all?
