Hey Guys, Just for heads up, in case anyone has same problem. It turned out alternator pulley. I've watched this video and they have mentioned the pulley needs to be replaced with every belt change service. So I took the cup off and I found dirt and dust inside it. No surprise why it was making that sound.

Hey @KoolMoeDee, What kind of of tools have you used in order to replace the pulley?

Hi Guys, I have same issue too. I'm very keen to hear any solutions. Cheers!

Yeah that's good idea! :) i'll do that.

Hi guys, Very good discussion i understood a lots from it. My Aurion (2007) makes exactly same noise. This is now my biggest headache. Where can i find those two idler pulleys? Any suggestions? or links highly appreciated. BTW: I found this diagram that has slightly more detailed. Cheers
