Hi guys. After realising that I can no longer take my car to a car wash, due to water leaking into the passenger side footwell, I decided to attempt to get to the bottom of it today. I've read numerous posts on here about it and they all imply that my drainage holes are blocked with leaves, causing it to spill over the top of my pollen filter and enter the car that way....THIS IS NOT THE CASE! I took a hose pipe and blasted loads of water down this hole, just to the right of the pollen filter: The passage didn't seem to block, and no water collected at the top of the hole entrance...but it all went directly into my footwell! What the hell is causing this?! What should I do?
