Hi, I have browsed the forum and across Google looking for a little help.



For a while now my Megane 3 1.5 diesel has been making what I call a whirring noise that is apparent when cold.



It changes with acceleration but clutch has no affect. Its worse when in lower revs and gears but goes if you floor it. To me it sounds like a bearing or pulley but its difficult to find. It seems more apparent inside the car rather than the engine bay.



I have found a video on YouTube with exact same noise but unfortunately no answers - https://m.youtube.com/watch?v=_A9UmMPW970



She's going in for a cambelt change with water pump and full service in a couple of weeks and has done 86000 miles.
