This used OEM BMW Windshield Side Trim / Seal, part number 7427873, is the left-side piece that seals the gap between the glass and the A-pillar. Also called a windshield side seal, it helps reduce wind noise and prevent water intrusion. It came from a 2020s G20 3 Series with either a 2.0L turbocharged four-cylinder or 3.0L turbocharged six-cylinder engine. Over time, the rubber can shrink or crack, leading to whistling sounds or interior dampness.
