Following heavy overnight rain there is a lot of water sloshing behind the left hand side dash.

I have checked the pollen filter and footwells, and they are both bone dry.

I also lifted the plastic grille under the windscreen to look for blocked drains, but it looked clean under there and I couldn't discover how it drained anyway.

I'm puzzled how the water managed to get into the back of the dash without wetting the pollen filter or the carpets, I assume it's somehow got into the heater.

 

Over the last few days the water seems to have drained away, I guess via the drain in the heater that's there to let AC condensate out.

 

I'm I bit concerned that the heater AC condensate drain is partially blocked.

 

Has anyone any information about getting acces to this drain to cleanit please?
 

I've had a similar problem - think I've just sorted it using this:http://www.briskoda.net/forums/topic/153416-leaking-water-ingress-funny-smell-inside-car/

 

I had a feel around and found the rubber plug, stuck my fingers in and loads of water and rotten leaves/silt came out too. My fingers reek!

Thanks for the link, I'll certainly have a look.

 

I just can't work out how water seems to have got into the heater but the pollen filter and carpets are dry.
