BMW Sunroof Drain Hose - Genuine BMW 51738197504

Product Information

A sunroof drain hose is part of a vehicle’s water management system. Since most sunroofs are not fully watertight, they are designed with channels that guide rainwater or wash water into drain hoses. These hoses typically run down the vehicle’s A-pillars, B-pillars, or rear pillars and discharge water safely underneath the car.

• Water leaks inside the cabin – wet headliner, seats, or carpets after rain or car wash.
• Clogged or blocked drainage – standing water in sunroof tracks or slow drainage.
• Moldy smell or damp interior – caused by trapped moisture.

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.
