Identify that Whine?

[Banjo789]

For the last couple of week the car (S3) has developed an intermittent whine from what sounds like the back left hand side of the car.

• The whine is only present at speeds above 40mph, and gets louder the faster I go - This happens the majority of the time.
• Some of the time the whine is only audible (40mph+) when I slightly depress the throttle - and will disappear again with my foot off the accelerator.
• The minority of the time can't here a thing.
• When it's whining, weaving side to side makes no difference to the sound.
• Swapping the tyres front to back has made no difference.

I don't need a stereo anymore as I'm driving around with the volume on mute listening out for this fecking noise to see if its getting worse.

My thoughts were:

1. Driveshaft
2. wheel bearings
3. sticking caliper - but I've got no vibration through the pedal.
4. Please don't let it be the Diff!

Any ideas guys?

i also have this, but can only hear between around 55-67 mph and its coming from front passenger side.

But i have a bolt missing from that wheel and i think the bearing have screwed up tbh. lol.
