This part is listed by BMW as BMW part number 33326782131 (33 32 6 782 131) and is described as the right rear upper wishbone with bushing/ball joint for F01/F02 7-series.
The wishbone (aka upper control arm) is key to the great driving characteristics of your BMW. The inner bushing naturally wears prematurely and the outer ball joint will also wear and develop play. When either becomes too worn it will ruin the driving experience and possibly cause a suspension failure. There are other arms and bushings in the rear suspension that should also be checked at the same time.
This part is manufactured by an aftermarket supplier of European auto parts, including many suspension components. While not carrying OEM status, this part follows the design of the original very closely and uses similar materials. An aftermarket part may even have the same TUV approval as its OEM counterpart. The brand may even be OEM to another manufacturer besides BMW. This aftermarket brand has a two year warranty - the same as Genuine BMW and OEM brands.
