Hi, My A4 Avant 2.7 multitronic has developed a noise when I pick up speed to around 35mph. I had new tyres fitted at the end of May which have now covered 2.5k. They are Michelin pilot sport 3 which I was told later are prone to being noisy ? Today I was having 2nd thoughts to the cause and hope it is not connected to the engine or gear box in any way. The noise is more of a whining humming sound and is related to speed as it gets worse the faster I go and then quiets down in sync with slowing down. I once had a wheel bearing go on a mondeo I owned but I wouldn't say this was as bad as that got. The car has been serviced regularly by a good independent garage and I will ask them to test ride it this week, only problem they are flat out and booked up for a month in advance but as a good customer I'm sure they will at least test it if I ask.
Any ideas from what I have described? a long shot I know but I hate this type of fault
