BMW Body Pillar diagram for 435i, 435i xDrive, M4

A body A-pillar trim panel is the interior or exterior covering that fits over the A-pillar, which is the vertical structural support running from the front of the roof down to the base of the windshield on either side of the car. This trim serves both aesthetic and functional purposes: it hides structural metal and wiring, provides a finished look to the cabin, and in many vehicles, helps house components such as airbags, weather seals, or wiring for sensors and antennas. It also contributes to reducing wind noise and improving overall cabin insulation.

• Loose, rattling, or detached trim that may vibrate while driving.
• Visible cracks, warping, or discoloration that affect appearance and fit.
• Compromised airbag performance or exposed wiring if the panel is damaged or not seated correctly.

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.
