My x-type makes a high-pitch whining sound when I get up to speeds of 65-70 mph, and I was wondering if someone can identify what it is. I know it's hard to identify sounds from a description so I have included a video. The sound I am referring to can be heard best at 00:20-22 on the video.


The sound is a bit subltle, but unfortunately happens at highway cruising speeds, so it's a bit annoying. Otherwise, at lower speeds it sounds fine. Any input, or just random speculation, would be appreciated.

 

hmmm...... seems pretty normal to me (its just the transmission winding up under load)
