Been told it was the drain tube leaking, but now it's linking again. I believe it's the shark fin.

6 months later and the shark fin is leaking yet again. I don't think Volvo knows how to fix it Or can't find the problem at first. It was drain hose leaking on driver's side 3 months later. Oh, it's the shark fin leaking now 6 months later, leaking again after a hard rainstorm today
