I have a 2013 Audi Q3 (right hand drive) and have been getting wet carpet in the passenger footwell. Audi have already taken a quick look at the car while it was in for a service. They claimed to have checked the plenum chamber and the sunroof and said it'd need to be booked in for a water test for them to investigate further. As this will likely cost a lot of money, I thought I'd take a look myself.
Have removed some of the interior trim, opened the sunroof and poured some water into the sunroof drain holes to see where it comes out to. This video shows that most of the water comes out from the outlet near the door. There are other drips that come into the interior of the car. It's not much, but I guess this should not be happening!?!?
Am I on to something, or is this test unrepresentative because I'm pouring more water in the sunroof drain holes than would happen normally (especially as the sunroof is usually closed)? What next? Removing the trim on the A-pillar? What will I see under there and how best to remove?
