Hi All, I'm hoping someone has heard this noise before, its been happening for a few weeks now, its really loud when cold, and seems to almost go away when hot although it can still be heard.
Seems to be from the RH front of the engine using a stethoscope.
I have had the belt off and felt the idler pulley bearings and they feel fine.
I cant hear it at idle.
Its a 2011 LCI X5 30D with 95km on it.
I cant work out how to post the audio file here (its an .m4a file) or the movie I took (its a .MOV file), so here's a link to a YouTube clip that someone else has posted that is identical to the sound mine is making (I cant get hold of the guy that posted the YouTube clip to see what the cause of the noise was unfortunately....)
Thanks :-)
