Default a4 b8 2011 humming noise in front end

humming sound comming from front end. it increases with speed and remains there when the car is put in neutral.

lifted front wheels off the ground to see if i could feel play in the bearing, felt nothing.

humming sound doesnt get any louder if i swirve left to right, makes me think it's not a wheel bearing.

turning with wheels fully doesnt make a cracking sound, cant ben the cv joints.

i didnt consider anything going to the rear axels as the sound seems to be comming from front wheels, manual transmission shifts fine have a hard time beliving it could be that

car has only 85 000km...

someone has a better idea?

thanks

Pascal

I have a similar issue. new to this forum. 2009 audi a4 2.0T 6-speed. 93k miles.

it is inconsistent with RPMs, cant hear it at idle or with revving. once I start driving, I hear the humming from the front end. turning doesn't change it, it gets louder, more prominent with speed. Shifting gears doesn't change it.

possible that it could be a belt pulley with worn bearings?
