Hello, could anyone please help with my predicament? I have a persistent problem with water leaking through the roof just above the rear seat on the passenger side. This seems to happen only when there has been heavy rain, or sometimes from going through a car wash.

I can hear it slosh around and then it gushes through the fabric and onto the seat. I took it to a VAG mech who changed the pollen filter, however this has not helped. I do have a sunroof, however it seems to be fairly well sealed? Could the drains be blocked?

Could anyone help please? Unsure if it could be the door seals?

Thank you!
