Metallic noise coming from front when wheel is turned left 270 degrees (with audio)

Hi guys

I've got a strange one. Yesterday I noticed that when my 2011 E90 335i was cold when I turned the steering wheel left 3/4 of a turn, I'd hear a small metallic whining noise. It sounds like metal on metal soft grinding. Could it possibly be the driveshaft? Depending on how a failing driveshaft or u-joint sounds, that's what I might have...

Some details about the car: no mods except the PPK tune, 88K miles, just had brakes and ATF (pan, fluid, mechatronic seal) done.

Here's a YT video link to the sound. I'm leaving a parking garage where I constantly am turning left to go around it. You'll really hear it around the 45 second mark and again around the 1 minute mark.

Any help would be appreciated!

suspect wheel bearing.
when the weight transfers to one side they tend to make noise on the way out. Since it happens whe you turn left, suspect right side.

Maybe power steering pump. Try a few rounds of turkey bastering out the fluid from the reservoir and replacing the fluid.
