You all are going to think I am crazy. This morning i got into my 2012 S5 in my garage. I had a jacket on the passenger side floor. I picked up the jacket to move it to back seat and it was drenched. I felt the carpet and it is soaked. Almost like a puddle. I felt the rear passenger floor and it was soaked even more than the front.

What can possibly cause that??? I have not left the car outside with windows down or sunroof open. Nothing like that. I am completely baffled. Has anyone ever heard of anything like this happening? All the leather seats and inside sides are completely dry. It is like there is a leak somehow that is coming through the floorboards.

Welcome aboard!

Let the dealer deal with stuff like this. Maybe it's something easy like a sunroof drain...

I had a latent defect in a poor seam weld under my sunroof, but more often this situation is resultant of a clogged drain hole/line. As uberwgn cites have your dealer deal with it asap as a warranty item.

If you have been running your air conditioner, especially if it has been humid out, you may have a plugged drain line. The a/c unit will produce condensation that should be going down a drain line. If it get plugged, the water will back-up into the passenger seat floor area.

Have you had snow in your area recently? Last year, I found that water from melted snow will pool under and behind the front seats when using the Audi rubber floor mats. This year I bought Weathertech Floor Liners to combat that problem.

Its this or the sunroof drain line. Both will ebnd up in same spot. Betting AC drain is plugged though.

Agree on the a/c drain, if you have been using the a/c
if after carwash or rain check the drain in the plenum area just below the windshield for water accumulation and getting inside the car thru the a/c inlet, which is also in the passenger side.

The dealership said there is a leak in the windshield. They said the water is coming in through the windshield and down behind the dash to the floorboard. Doesn't make sense to me. I pick it up this week, so I guess we will see.

That's what they first said about mine too, and even replaced the glass, but again it turned out to be a defective weld under the sunroof in my case. Install some rubber floor mats so you'll know immediately without further wetting your carpet - glad I did.
