Dealer should cover this under CPO. The following is straight from the CPO warranty:
"Your Audi technician is authorized to decide if a component is worn as opposed to having a factory defect. Warranty covers items that fail due to a defect in material and workmanship; warranty does not cover items that fail due to wear. Many components on your Certified pre-owned Audi will wear based on driving technique, exposure to elements or gradual normal deterioration. Items that have failed based on any one of these criteria are not considered to have a factory defect and would not be covered under your Audi Certified pre-owned Limited Warranty."

Sorry guys. I forgot to post my outcome on this issue.

So what I found out like all of you have already stated, the front glass seal to body gave way which caused the leakage in the cabin.

I had the glass replaced ($600.00). The shop just reset the sensors, but when I got on the road and used my cruise the lane assist and adaptive cruise would go out.

I got fed up and took it to the stealership. They had to do a full reset on all the front sensors. $1300.00 later, fixed.

Bought a 2014 A8L in March. Have had for 8 months and only had one issue with dealer on performing alignment and getting car to drive straight again (car drove straight, no problems, but wanted to make sure everything was ok before out of warranty). Rained 5 days ago. Found water in passenger floorboard. Thought sunroof drains were problem as this had happened on my 2009 A8 (and thanks to this forum found about about lawsuit that Audi lost regarding the sunroof drains on that model). Pulled off wheel liner, ran weed whacker line thru. Perfectly clean. Attributed to my buddy not closing the sunroof all the way the 4 days earlier. Then, the second rain and puddles in passenger floorboard. Got out the hose and found problem quickly. Windshield seal had released between the center mirror and passenger door pillar. Very little pressure from inside glass made the gap so obvious. Incredible to see that other Audi's have the same problem in the same area. I then correlated this to the extra wind noise I had heard that showed up two weeks before on the passenger side. This does appear to be a manufacturer defect. Will be headed to the dealer here in Houston to see how they will handle. Of course, just crossed the 50K mile mark as well. Drying out myself as no one else will care about your vehicle more than you. Will update on what I find out for others in the future.

Told by dealer that this was not very common, although they new just who to send me to for resealing windshield. Now back to quiet and leak free.

Possible causes

One possible source of the leak is an unnoticed pinhole in a seam hidden under the molding, Vandale notes, adding that while small this can cause big problems.

Windshield leaks actually happen less than they once did. “Windshields used to be put in with a rubber gasket, then [manufacturers] went to a butyl tape and now they have gone to urethane and the windshield is actually part of the structure of the body,” he explains.

Still, there can be skips in the urethane and as a result you don’t get a good seal, Vandale notes. Or, if the windshield itself has been replaced at some point, there’s also a chance of windshield leaking if a proper seal isn’t obtained, he says.

Finding windshield leaks

To test for a leak, Vandale recommends gently showering the car with water. The lower the water pressure used, the faster the vehicle will actually leak, he explains. If a hose is put on full force, the water will bounce right off.

Also, if you have a wind noise in the vehicle, Vandale recommends using soap to detect the leak because where wind can get in, so can water. “We do a soap test where you take soap on a wash mitt and you go all around the window and then you turn the heater blower on high defrost,” he says. “You make sure the windows and the doors are all closed, and when you stand outside, you’ll see bubbles coming out.”

How to fix a leaky windshield

If you find the leak, it can be relatively easy to do a windshield leak repair with the right materials. “Never use silicone,” Vandale stresses. Silicone expands and contracts in the heat and the cold. What’s more, once you’ve put silicone on a seam, you can’t reseal it with the proper sealant because it won’t adhere to the silicone, he says.

Instead, he urges those seeking to fix pinholes to use special seam-sealers that can be acquired online. These sealers come out of a tube and can be easily applied. If the pinhole is underneath the molding on your windshield, the molding can be pried up a bit and the seam-sealer squeezed in. It will dry in just a couple of minutes and the molding can be pushed back in place.

Meanwhile, if the leak is caused by a skip in the windshield sealant, Vandale recommends using something that always stays pliable, like a butyl sealant. To apply this, a caulking gun is needed. “We use an air-caulking gun so that it’s done under pressure,” he says.

After letting the sealant dry for a few minutes, Vandale recommends repeating the water test. If all goes well, you will be free of leaks and happy to be in your car no matter the weather."

It is 2014 A8 with 31k when I bought it few weeks ago. One owner, super clean(like new), no accidents. As i reported in other thread I had air noise problem by sunroof. Luckily you guys pointed towards the right direction of windshield.
Called local audi they said yes we know but your factory warranty ran out 2 months ago. Stopped by at large indy body/glass shop, adviser said hey I used to work at audi bodyshop just go there. I thought ok fair. Called them, the girl goes well we own separate glass co so you have to go there. Of course she gave me wrong # so as I was driving by Safelite decided to stop there. Sure it's $120 to take it out and re-seal, but we will order replacement non OEM glass just incase. Picked up the car today. Noise is gone. They said it's unbelievable and took me back to show the glass. Both the front desk and tech guys were truly amused. One picture shows that it's original glass, second shows the seal on the side, the 3rd shows the top where the SEAL is missing. Crazy.
Of course the bad news is that the original window cracked.
I'm glad it's all fixed before any water damage but at the same time you just wonder.. Do all of the cars were assembled during Octoberfest?

Hi,

Any news from Audi to take responsibility from this typical issue with high end cars. I think if this will not be resolved by Audi I will think twice before ever by other Audi. It is ridicules if they have not have recall and replacing or fixing all windshield in these cars. It is many report on the same issue just in this forum. Please let me know if is any lawyers out there to start a class action suit against them. I am in. Please let me know.

Had same problem with my older D3 ( i have a D4 now)
so under the sunroof you have 2 drains. they get block from debris
easy fix, just go to your mechanic and with high air presser he opens the drains.

I think it's another defective manufacturer issue on this car. Every since this car made 90,000 miles on I've having the roof leaking water, constant ABS braking issues since 75,000 miles. Rear coolant pipe leak you name it. Im done with Audi after I get rid of this car.
