How to Solve the Sunroof Noise Issue in a 2018 Superb?
2 Answers
Here are the solutions for the sunroof noise issue in a 2018 Superb: 1. Insufficient lubrication of the sunroof sliding track: The noise may be caused by poor lubrication in certain areas. Try applying some grease. 2. Dust accumulation in the sunroof track: Keeping the sunroof open for extended periods can lead to dust buildup on the sliding track. Cleaning it should eliminate the noise. 3. Loose screws in the sunroof: Long-term use may cause certain parts or screws to loosen. Tightening the screws should resolve the noise. Preventive measures: Use a damp, soft cloth to clean the sunroof sliding track. After drying, apply butter to the track. For rubber or plastic components, apply talcum powder after cleaning and drying to protect them. Regularly inspect the sunroof and tighten any loose screws to prevent noise. If the sunroof is unused for long periods, the sealing strip remains compressed, reducing elasticity and causing parts to age. Periodically opening the sunroof to allow parts to move can extend its lifespan.
My 2018 Superb's sunroof was also squeaking a lot. I thought dust might have gotten into the tracks, so I removed the interior trim panel to check. I found sand and small stones in the tracks. I cleaned them with a toothbrush dipped in water and applied some sunroof-specific lubricant, which significantly reduced the noise. Later, I realized that the Superb's sunroof design has relatively large gaps, and closing it properly when parked can help prevent debris from entering. Now, I make sure to clean the tracks every time I wash the car to prevent noise. I'm also extra careful when driving over speed bumps, as the noise can accelerate component wear. I recommend trying cleaning and lubrication first—it can save you a hundred bucks or so in repair costs.
