I just got my car back from the dealer after they had it for six days trying to resolve my clicking noise in the L/F wheel when making turns. They needed that time to diagnose the problem, get approval from BMW USA, order the parts, and perform the repair. Here is the writeup from the repair order:

"Microscopic slippage of contact surface interface between inner brake disc and wheel bearing flange. Road tested vehicle. Referenced SI B34 05 17 for noise while cornering. Removed both front brake discs, cleaned both wheel bearing flanges, and installed the friction rings. Reinstalled brake discs. Defect code: 3121993900. Labor operations: 34 11 220, 34 99 000."

The parts they listed were as follows:

34-10-6-887-529: Disc for Higher Coefficient: 341099 (Qty. 2)
36-13-6-781-151: Wheel Bolt, Black: 362010 (Qty. 10)

I have only driven the car home from the dealer but I did not hear it. I will be listening for it going forward.

Hope this helps.
