Guys my 2008 Aygo is driving me insane with this strange sound that appears only when moving, regardless of speed, but gets louder the faster I drive, and decreases as I slow down, it almost sounds like an electric sound, so hard to describe, also sort of sounds like something rubbing against the tyre wall. Its definitely coming from the engine bay area I think. Its not any louder with the window down.
Its been happening for a few months now but Is definitely getting more prominent.
I've added a video from my drive tonight. If you concentrate from 30 seconds onwards with your volume UP you should hear it...
