Original BMW Windshield Washer Fluid Reservoir Filler Cap, BMW i3, X3, X5, X7, Z4 and Mini Cooper (2004–2024)

This Original BMW filler cap, part 61-66-7-375-587, closes the windshield washer fluid reservoir filler neck on BMW i3, X3, X5, X7, XM, and Z4 models, as well as several Mini Cooper models. BMW calls it the cover for the filler pipe. The cap weighs 9 g (0.32 oz) and has been in production since December 2013. The washer reservoir sits under the hood and feeds fluid through the pump to the windshield nozzles, and the cap keeps that fluid in and dirt out of the filler neck. It is sold by the piece.

Original BMW Parts carry a 24-month parts warranty.

This number replaced the earlier cap 61-66-7-268-513, and BMW marks the change as exchangeable retrospectively. That means the current cap also serves cars that left the factory with the older part. Because of that interchange, one cap covers chassis as far apart as the E83 X3, the I01 i3 and i3s, the G05 X5, and the G07 X7. BMW's parts data also shows it on a long run of other BMW families, from the E60 5 Series and E63 6 Series to the F48 X1 and G01 X3.
