I have a 2016 dig-t. Recently I have been experiencing a rumbling noise (almost like driving with a flat tyre) when I go over 55mph. This doesn't happen every time I go that speed and stops as soon as I pull over for 20secs. I have new and tyres and the wheels have been balanced. Also new brake pads. None of the wheels are overheating.
I have had this in 2 separate garages and still the problem persists.
