How to fix a leaky sunroof in an Audi A4?

I have noticed that my sunroof is leaking in my Audi A4 and it's causing water damage inside my car. What could be causing this issue and how can I fix it?

It is likely that there is a clog or blockage in the drainage tubes in your sunroof, causing water to accumulate and leak into your car. I suggest checking these tubes for any debris or blockages and clearing them out. You can also use compressed air to clear out any stubborn clogs.

Another possible cause could be a damaged or misaligned seal on your sunroof. Check for any cracks or gaps in the seal and replace it if necessary. If the seal is misaligned, you can adjust it to ensure a proper fit.
