What are the most common issues with the Audi A4's sunroof?

I just bought a used Audi A4 and noticed some issues with the sunroof. It seems to get stuck sometimes and doesn't fully close. I'm worried about water leaking into the car. Is this a common problem with this model and how can I fix it?

The most common issue with the Audi A4's sunroof is a malfunctioning seal or track, which can cause it to get stuck or not fully close. To fix this, you may need to replace the seal or clean and lubricate the tracks. If the problem persists, it is best to take it to a certified mechanic for further inspection.

I had the same issue with my Audi A4's sunroof and found out that it was due to a faulty motor. The motor was replaced under warranty and I haven't had any problems since. I would recommend taking it to an authorized Audi dealership to have it checked.
