X3 screech when revved. Advice needed.
« on: May 25, 2018, 10:15:29 AM »
Hi all, just joined the forum for some advice. Had my X3 for a few months and love it. 2006, 100k miles but runs well. This morning while driving it started to make a screech / high pitched whining when revved. See attached video. Any ideas what this might be ? Many thanks, Steve

see video below

There are a few things it might be, including a drive belt tensioner bearing worn, an worn alternator bearing or pulley clutch (if it has one) on the alternator. I would get it looked at as soon as you can.
If in doubt, and all else fails - read the instructions!!   :) :)

Water pump and air conditioning compressor clutch to add to the list of possibles.  Might be the viscous damped fan clutch too.
:type: Never anthropomorphise computers. They hate that.
