toadeh. I've noticed from about Monday last week that my Audi has started to make a loud whirring noise which sounds like its coming from the front of the car, seems to be loudest between 30-50mph. at first i thought it was just road noise but after more googling I don't think it is.. Possibly tires or a bearing as my partner curbed it a couple SkiWm1.
