This refers to the decorative and protective molding found along the top edge of a 2007 BMW 3-Series (E90 chassis code) on the driver’s side. This component typically serves to cover the gap between the roof panel and the side body panels, enhancing the vehicle’s aesthetics and contributing to a streamlined appearance. It can be made of various materials, such as plastic, rubber, or metal, and may incorporate features like seals to prevent water leaks and wind noise.
A properly functioning piece provides several benefits, including improved aerodynamics, protection against rust and corrosion by sealing gaps, and a refined visual finish. Over time, exposure to the elements can lead to wear and tear. Deterioration can manifest as cracks, fading, or detachment, potentially compromising the vehicle’s structural integrity and appearance. Maintaining this part is crucial for preserving the vehicle’s overall condition and value, especially in older models like the 2007 E90.
