HI Peter

Thanks for your answer. My Volvo dealer assures me they have balanced all the wheels. In fact the wheels have all bee swapped around a couple of times and still the vibration persists. Could it be caused by the uneven tyre wear? I also drove a new XC90 T6 yesterday with just 700 miles on the clock and that had the low frequency vibration - which actually feels more like feedback from a bumpy road than a real vibration. It didnt have the high speed vibration though.
