Roof leaking

[Jo.]

Hi, I have an Audi A4 cabriolet 2004. The rood is leaking in the rear left passenger side. The interior is soaked to the point its dripping onto the seat. I can't see where this is coming from. I cant afford a new roof at the moment and I don't have a garage. Has anyone else had this problem that can give me some advice please? 

 

Thank you.

Might be worth seeing if any glue has come unstuck especially around the rear window. Might be worth speaking to a roof specialist.
