Hello, Newbie here. I bought this car brand new in April '07. Since then, it has had two new prop. shafts. It seems to have been "out of balance", causing vibration. Second time, I recognised the noise and got the car in, checked and fault confirmed just (a few days only) before the warranty expired. Phew! Avoided £1400 bill. Is this a known problem with the Quattro on this model? I think I need to get rid of this car - but have I been unlucky, and got a 'bad' one, and another one would be OK, or would another one do the same? Would not want to move away fom the A3 - I love this car, as I did its 1.8T petrol predecessor (in which I did 103,000+ miles in 8.5 years, from new). Thanks for any information. N.
