Hi Everyone,
I have an 2012 Audi A6 C7 Allroad Avant, when driving over 20mph I have a rythmic humming/vibration from the front. It seems to cycle so will make the noise/vibration for one second then off for one second and so on. This rythm changes in speed and frequency the faster I go. The noise dosent stop when I put it into neutral when travelling or does the noise change accoring to revs, only speed. I think the speed in the rhythm also changes when cornering. Any help would be much appeciated!
