Product Information

BMW Door and Window diagram for 328i, 335i, 335is, M3

A door window belt weatherstrip (also called a belt molding, window sweep, or outer window seal) is the rubber or rubber-coated strip that runs horizontally along the base of a car’s door window where the glass meets the door panel.

• Water Leaks into the Door or Cabin: Rainwater seeps past the worn seal and may collect inside the door or drip into the interior.
• Wind Noise at Highway Speeds: Gaps in the seal allow air to whistle or roar into the cabin.
• Increased Dirt or Dust on the Glass and Door Interior: The strip no longer wipes the glass effectively, letting debris enter.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
