Original BMW Windshield Washer Reservoir Filler Pipe for BMW 1 Series, 3 Series, and X1 (2006–2015)

Cracked filler necks make topping up washer fluid slow and messy, and this Original BMW filler pipe for the wash container restores a clean fill path to the windshield washer reservoir on the E8x 1 Series, E9x 3 Series, and E84 X1. Over time the stock filler neck can crack, which makes it difficult to pour fluid into the reservoir without spilling. The filler pipe connects the opening you pour into with the washer fluid reservoir below it. This replacement piece weighs just 80 g (0.2 lb) and is made in Germany.

Original BMW Parts carry a 24-month parts warranty.

BMW calls the part a filler pipe for wash container. The current number, 61-66-7-135-409, has been in production since May 2004 and supersedes 61-66-4-419-445, which BMW marks as exchangeable retrospectively. A further cross-reference, 61-66-7-075-099, also points to this pipe. Because the same pipe is shared across the E81, E82, E87, E88, E90, E91, E92, E93, and E84 platforms, one number covers sedan, wagon, coupe, and convertible bodies within the fitment range.
