Hi all Im a new member to this site and was just wondering if anybody could help me. I have a 1999 V plate A3 1.8T Quattro and i am getting a humming noise which sounds like possible gearbox. It happens generally when on the motorway and when i accelerate gradually. The car also has a 5 speed box and i have noticed that most 1.8T quattros come with 6 speed boxes. Will the 5 speed box be hard to source if mine is on its way out? Any help would be much appricated.
