Hi! This buzz comes randomly when i drive, sounds a little like a small clicking. Goes away in a few seconds. I have a feeling that it comes from the right side, but i can be wrong. The fan perhaps, even if its in front of me...However i am going to let my meccanics change tha camshaftbelt soon, since i did not get a clear picrute of when it las was done, the latest info is from 2013, and the car has driven 2-30000 km sfter this, so to be on the safe side....
