How to Solve the Sunroof Noise Issue in BMW 5 Series?
2 Answers
Methods to solve the sunroof noise issue in BMW 5 Series: 1. If the sunroof rubber seal or weatherstrip is aged, open the sunroof fully and apply a maintenance spray on the seal; 2. Loose sunroof screws can also cause roof noise and sunroof noise, and may even pose a risk of the sunroof falling off. Locate the sunroof screws and tighten them. The domestic BMW 5 Series is a product of the German BMW company, classified as a mid-size sedan. In terms of body dimensions, it measures 4998mm in length, 1901mm in width, and 1559mm in height, with a wheelbase of 3108mm. The BMW 5 Series is positioned between the sporty and stylish 3 Series and the elegant and noble 7 Series, perfectly blending dynamism, elegance, and the functionality of a high-end business sedan.
I've been driving a BMW 5 Series for several years and encountered a sunroof rattle issue. That squeaking sound was particularly annoying. Later, I discovered it was due to dust and sand accumulation in the sunroof tracks, so I cleaned it myself. First, use a soft brush or dry cloth to clean the tracks thoroughly—avoid water to prevent rust—then spray some silicone-based lubricant (never use oil-based ones as they damage the seals). The noise disappeared quickly. If screws are loose, they can also cause rattling; check and tighten each fixing screw on the sunroof frame. Inspect the seals for aging—replace them if cracked or hardened. Regular maintenance is crucial, like cleaning and lubricating quarterly to prevent recurrence. BMW sunroofs are quite good among luxury cars, but neglect can lead to minor issues. Handle DIY repairs gently to avoid bending the tracks. If the noise persists after trying these steps or if opening/closing becomes stiff, visit the dealership—it might be a worn slider or internal motor problem.
