2016 F80 Manual
ASD coded off
Can't say I paid attention to this earlier but this Whine is rather annoying. Checked my brother's 2016 DCT and that doesn't have it. Just want to confirm with anyone who has a manual though I don't think this is tranny related. Goes under and down with rpm. Idler pulley bearing?
Update: 11/28/17. The culprit was the upper Deflection Pulley. It's been replaced. Noise is gone.
Thank you all.
