Hello,

So I have officially moved to this side of the fence after trading my VW passat CC for A6 S line black edition 2015 and experienced an issue straight after leaving the dealership. Just wonder if you guys had similar issue to me. When I drive on the motorway at the speed of 120km/h. There is a vibration on the front seats specially on the head rest at that speed. It is strong enough that resting head is uncomfortable. I can also feel it on the passenger seat if I place my hand on the head rest. You can't really feel it at the speed lower than 100km/h. I believe the issue issue with either buckled or unbalanced rear wheel/wheels. I had same issue on my past CC. Any thoughts? I booked the car to be checked anyway.

Thanks!
