We have had some odd penetrating rain here over the last couple of days. Found a puddle on my drivers floor mat this morning, and I've recently sealed and fixed all the usual suspect leak points in plenum area.

Yes I think the thunderstorm the other night is the suspect... the rain was biblical... nearly built an ark!

Maybe should have made that a thing at Summer Camp... mine is bloody leaking again too now...

I've attacked it all with silicone before, but looks like I need to go in for another attempt... The pollen filter is pretty filthy, so that's on the list of things to replace aswell, before I seal it all up again
