hi i've just bought and audi a3 1.6 fsi, absolutely love the car but when i picked up the car noticed a high pitched whirring noise through low speeds but thought nothing of it thought it was just the natural running of the car but after looking through some history it looks like the previous owner has reported this to audi and they've diagnoised as coming from the gearbox but to no rectification. i persume thats when the owner got rid of the vehicle because it'll be out of warranty. the car seems to run fine doesn't miss a gear and is dead smooth in every gear, no clunking or stiff changes, just the noise under low speeds.
Does anyone have any ideas? is it a case of jus low gearbox fluid?
