BMW Fender Liner - Genuine BMW 51718193811

Product Information

A fender Liner Extension (sometimes called a fender trim or wheel arch molding) is a protective and decorative strip that is attached along the edge of a vehicle’s fender, typically around the wheel arch. It serves both functional and aesthetic purposes:

• Protection: Prevents scratches, dents, and chips from road debris, stones, and minor contact.
• Aesthetic: Enhances the look of the vehicle by giving a finished, stylish appearance.
• Corrosion barrier: Helps shield painted metal areas near the wheel wells from moisture and rust.

It is usually made of plastic, rubber, or metal (with chrome or painted finishes), and can either be clipped, bolted, or adhesively mounted.

• Looseness or detachment – molding hangs off, rattles, or won’t stay in place.
• Damage or wear – cracks, dents, fading, or peeling of the trim.
• Rust and paint issues – trapped moisture leads to bubbling paint or corrosion around the fender.

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.
