This sunroof drain hose with OE part number 54107212746 is suitable for 2011–2017 BMW X3 (sDrive28i, xDrive28i, xDrive35i) with chassis F25, used to replace the original sunroof guide hose that is prone to aging, blockage, and cracking leakage.
Made from UV-resistant and bend-resistant flexible rubber, this hose is not easy to harden and crack under the sun exposure and low-temperature snow conditions of the roof. The inner wall is coated with a low-friction smooth layer to reduce pipeline blockage caused by fallen leaves and sediment. The original same bending shape can be embedded along the roof sheet metal cavity without damage, and the interface clamping position matches the original buckle completely, avoiding loosening and falling off.
After installation, it can smoothly guide the rainwater seeping from the sunroof gap, and avoid common failures such as moldy ceiling, water soaking of roof interior, A-pillar water accumulation, and peculiar smell in the car. The finished product has passed the high-pressure water flow durability test, suitable for rainy and cold regions. It has a low maintenance threshold, can be easily disassembled and installed by yourself, and solves the common sunroof leakage problem of BMW X3 at low cost, extending the service life of the car interior.
