Hello All,

I had a engine leak from the oil cooler housing that has been fixed recently. However since then I am hearing a squealing noise from the engine bay area. Please see the video here;

Does this sound familiar, could it be the alternator pulley or the idler pulley? BTW, this is a 2008 528xi.

Thanks in advance for any inputs!
