I have a leak in the passenger foot well. I can't find the cause and it is intermittent. 

I am wondering if there should be a lid on my pollen filter?

Meanwhile, I have drilled a hole in the floor grommet, so it should prevent severe flooding. 

I've had the exact same issue. Had to have the pollen filter housing replaced. Not the most expensive part to change but definitely should cute the issue.

Cheers

I finally took the filter out to have a look. The problem was the gasket beneath the filter was damaged. I replaced it about a month ago, and so far the problem has not returned.

Glad you got it resolved 🙂
