I can't recall anything changing depending on what I do, the only thing that braking affects is vehicle speed, which in turn slows down the sound. Doesn't seem to matter if I'm coasting or under load, as it is a persistent noise that goes away, when the components warm up. But to answer, it does it in both. I'd say it doesn't increase while cornering, as I have tried doing that while I could hear it and nothing changed. Neither forward or reverse seems to affect it. I tried moving the wheels, but in that case to check closer I should have to remove the wheels, as for the winter I'm using ones similar to van wheels (don't know the exact terminology for this). Do you suggest, that I should do this? To add: I also have a oil change coming up, dash shows 300km more, so should I check for something there?
