Water in passenger footwell


Recommended Posts

Hi, the passenger footwell on my Audi TTS MK2 is absolutely soaking. I have checked the drains beside the windscreen wipers and they are clear. Could this be a problem with the air con?

Thanks

It could be condensation from the aircon; it could equally be a leaking heater matrix or a leaking windscreen seal. Does the water appear after rain? Do you need to top up the coolant level more than once per year.

One of my cars Is an 8J TTS I Sometimes get a little water coming in the passenger footwell from the bottom door seal. I CBA to replace the whole door seal so I just leave it. As I have custom rubber floor mats it just creates a tiny puddle on random occasions. But if it is leaking badly you should look into it. Also worth checking the frameless windows are seated correctly as this can cause leaks. Also there is a drain hole on the bottom of the door which sometimes gets blocked, as the door is designed for rainwater to run down the glass and though the door not over it. 

Regularly applying rubber conditioner and cleaning the seals helps prevent issues. Something like liqui moly gummi-pflege works very well. (especially during winter when the rubber can freeze) 

If you think water is coming in via the HVAC - you could first try removing the pollen filter which is super easy - no tools required and see if it is damp.
