strange noise in cabin

Hi, i'm getting two annoying and weird noises from my car. One is constant buzzing, and one coming from the headlights. I'll post videos of both. The interior one sound like it's coming from the blower motor, but i took it yesterday off and the noise was still there, no change...

My 2010 2.0tdi quattro has developed a strange noise kinda like a hanging exhaust, but it's not that. Lol. It only happens when in gear, sitting at idle it's fine no overheating etc but when u take your foot off accelerator it's OK. The noise isn't in engine bay and sounds worse inside the cab...
