I'm normally parked on the level at home and other than slight ingress in the boot, the cabin stays bone dry. Yesterday I had to park facing uphill and we had heavy rain during this time, come late last night and I'm off to fetch the wife from work and instantly hear this gurgling sound which progressively got quieter after 5 or so miles, wife opens the door to get in and spots the water on the floor straight away.
So the noise I heard was, I guess, the fan I noticed when changing the pollen filters last summer, churning the rainwater that had got in there and flung it out the foot vent?
The p38 is quite new to me but can anyone confirm my thinking that rainwater in the fan housing can only get there via the pollen filter lid?
It's never leaked in before but this is the first time it's been parked facing uphill which may be a clue..
