Hi, I have an a4 1.9 tdi auto (115) I have a vibration which is only intermittently apparent between 72mph and 85mph and more uphill or on the flat (under load) I have balanced all 4 wheels and swapped front to back as I thought might be duff tyre, have checked all wheel bearings ect, the vibration is not through the steering but through the floor of the car it does it in all gears and different engine speeds, the gearbox and engine run very smooth with no fault codes in either and changes gear fine hot and cold. It is only noticable at this road speed, I'm thinking driveshaft or torque converter? Any ideas? Or known issues?
