I have a 2006 A3, 170 bhp 2.0 tdi. It shakes very badly between 55 & 70 mph, though not through the steering wheel, more the whole car. If you drive through it it's not too bad, but if you find yourself travelling at a constant speed between 55-70 it's very bad. Any help would be much appreciated as it's driving me mad. Mooey
