I'm experiencing an issue and not sure how to pin-point and troubleshoot it. When driving at highway speed on windy days, there is a noise coming from the rear windshield area (passenger side bottom corner?) that sounds a bit like when you blow through a blade of grass held between your thumbs, but much louder and stronger. It is not steady, and seems to correspond with the gush of wind. I asked my VW dealer about it, and they said it is not covered under warranty since my car as roughly 95k on the odometer (it's only a 2013). They recommended I contact an auto glass specialist to replace the rear windshield, but I'm not even sure that's where the noise is coming from. It does not seem weather dependent, as it started back in the summer months and continues to this day. Sometimes, I think the rear windshield (if that's actually the source of the noise) is going to be ripped out of the car!

Has anyone else noticed this in their Passat?

You have an SE DSG which means a sunroof I believe. I'd highly suspect a minor issue with the drain hose. Very annoying if constant.

Our SEL develops a bit of noise in rainy weather as water is drained from around the sunroof area. Unusual in anything but very heavy rain.

Had the same issue with my 2014 TDI, same window. The fix in my case was to replace the long rubber seals in the doorframe that seal around the window when closed. Problem solved.

Had same issue with left rear passenger door and window seal.. Now I hear the right rear passenger door. Got the left one replaced under warranty, right one will be on me, or I just turn the radio up a little more.

Thank you all for sharing this post. I have this problem since day one and as usual it is "NORMAL" for dealership technician.

I have this problem with my 2015 model, dealership confirmed the issue and ordered parts for replacement. The service writer that I spoke with wasn't in when I came to pick the car up, so I didn't hear exactly what the issue was, but it was said to be a seal that requires replacing the glass with it as well.

I have this problem, my dealership told me same thing. Service manager said "These new passats aren't built in Germany and all of them do it, said it's normal"
My interpretation of this is just laziness. Going to try a new dealership with the problem if I ever get enough free time. That is, if I don't trade for a Golf tdi.

I am sure VWoA would love to hear this. If these cars arent built in Germany they are a pos....that is my interpretation of that comment. Sure the sevice manager time at that dealership would short lived.

I appreciate the replies so far, but I'm convinced the noise is from the rear windshield, and not the rear door. Has anyone had issue with the weather seal failing at the rear windshield? Is there an adhesive I can reapply around the windshield without removing it from the vehicle?

Let me see here... You pay $30k for a car and it's okay to have defects? I don't think so! NO DEFECT IS NORMAL!

Allow me to share a personal experience... My older son purchased a truck which became progressively more reluctant to stop. I mean REALLY reluctant! After several failed attempts to address the problem I was informed by the service manager that the truck stopped just fine when cold. At which point I about came over the counter after this moron. I had previously shared that a bumper to bumper warranty was just that and that I didn't care if it involved bolting a new truck between them.

Luckily the owner of the dealership was close by and had heard the exchange. He wasn't too pleased and instructed his employee to take a new truck off the lot and use it as a donor for every part needed until our truck was repaired. Amazingly later that day a call saying that all was well. And it was.

Laziness and uncaring is endemic throughout the automotive industry as it is just about everywhere. It seems the motto is to do as little as possible to slide by and to extract the maximum dollars in return for the minimum effort involved.

Do yourself and the owner of the dealership a huge favor and inform him or her about the treatment you've received. If you get a shrug of the shoulders, then make tracks away and never return. If, on the other hand, the owner quietly tells you that the problem will be immediately addressed and it is, then you'll have done both yourself and the dealer a huge service.

Give your dealer at least the benefit of knowing. See what happens and judge the dealership based on what happens and how the situation is rectified.

Oh... I stand by drain noise. Our SEL has a slight hint of this in wet weather when low pressure forms at the vent end of the tube and water is literally being vacuumed from the sunroof channels.

Test your theory by temporarily taping the entire perimeter of the rear door quarter window, spanning the glass/window frame/door top interface. If a test drive reveals no change in the sound, since some report the problem was with the rear window channel weatherstrip, tape around the main window perimeter, again spanning the glass/channel interface. In no change, do the same thing with the backlight (what you call "rear windshield").

I'd be surprised if yours is a different problem than others have had.

Chris,

Your idea of taping around the suspected area is genius! I can't believe I did not think of it. I'll try that as soon as the weather warms up around here. Tape won't stick so well when it's -17 outside! Well, at least overnight...

nord,

Thanks for the drain suggestion. I'll try that if taping the window does not reveal the source.

Mysterious wind noise problem identified and solved...

In preparation for a road trip last month, I was cleaning the interior surfaces of my car's windows. While wiping the rear windshield, the upper right corner lifted up at least 1". I brought it to a local auto glass business (not nationally known, BTW) to have them reseat the rear glass. The guy at the glass place said it looked like the factory did not apply primer to a large area of the edge. Repair cost $230.

Wow, good catch and congratulations on the solution!

That's the very last thing I would have suspected. Out of curiosity, did you try diagnostically taping the backlight (rear windshield)?

Did you have any water intrusion in the trunk?

I never got around to trying the taping method you had offered. The problem was very sporadic and difficult to replicate. They were no obvious signs of leakage inside, but once I discovered the problem at the upper corner of the window, I then noticed minor water marks on the inside surface of the rear glass near that corner. It wasn't leaking bad enough to make it all the way to the trunk.

Of course this begs the question: if this was the original backlight and not a replacement, were you the only (and unlucky) victim or was this a wider, but limited, production issue that wasn't bothersome enough for the majority of owners to notice (noise or water leakage)?
