Original BMW Rear Wiper Arm Cover Cap for BMW X3 E83 (2004–2010)

Built in Belgium by BMW, this rear wiper arm cover cap covers the rear wiper arm assembly on the 2004–2010 BMW X3 (E83). It is a small cap weighing 7 g, and it often goes missing, especially after a trip through an automated car wash. Wiper arm caps like this hide the retaining nut that holds the arm on its drive shaft and keep water and grit away from that joint. Replacing a missing cap restores the factory look of the tailgate.

Original BMW Parts carry a 24-month parts warranty.

BMW names this part the wiper arm cover, and it has been produced since July 2005. One part number serves the whole E83 range, both pre-facelift and facelift. It covers every engine BMW offered in the E83, from the M54 and N52N gasoline sixes to the N46 four-cylinder and the M47N2, M57N, M57N2, and N47 diesels. Engine choice does not change the part, so the only thing that matters when picking one is that your vehicle is an E83 X3 needing the rear cap. It is sold as a single cap.
