If you roll down the window you can look at the top of the glass; if it's acoustic it'll be a sandwiched cross-section.

Interestingly, Safelite indicates it could be either or -- there's laminated and non-laminated choices for the windshield and driver's and passenger's windows, and no lamination for the back windows, for both MY2017 and MY2018. For MY2016 there's only one, non-acoustic choice.

I'll check for the sandwich slice. But, as it is with a better rear camera in the Prestige versus other models, I'm betting the front / side glass is acoustic. If it isn't then it has to be almost a marketing thing -- the cabin is so quiet it's then effectively a distinction without a difference.

My 2018 is a Premium+ w/o Acoustic glass and I have the wind noise issue .

I've got a 2017 Prestige. Neither the front nor rear side glass is acoustically laminated.

In the UK the acoustic side windows only come with privacy glass option...

I have a 2017 Prestige and just recently started noticing a little wind noise towards the top of the driver's side window. Since this car is so quiet it was quite noticeable. I did a little searching online and found a product called Gummie Pfledge Stift that is a small bottle of product meant to condition rubber seals. I applied it to all of the door seals (both on the doors and on the car itself) and the wind noise is completely gone. I applied it twice allowing it to dry in between applications and I think I noticed the seals expanding a bit (they seem puffier to the touch if that makes sense). I also cleaned the seals with a bit of interior cleaner and a microfiber cloth first. I bought the stuff off of Amazon:


You can probably find it a little less expensive elsewhere, but I wanted to try it quickly and have Prime shipping. Although I see it's a few dollars cheaper now than it was when I bought it earlier in the week. Anyway, I would recommend it if you are hearing the noise.

Thanks, that's great info. Out of curiosity, did it sound like wind noise entering the vehicle or just the outside turbulence?

To me it sounded like the window wasn't closing all the way, but when I pulled up on the window button it didn't go up anymore. Almost like it was open just enough to let some wind faint wind noise in.

The wind noise is starting to annoy me. No solution for Premium Plus cars (with nou acoustic glass)? Even finding acoustic glass separately is hard...

Edit: made some research regarding parts needed. It seems that you don't need to change other parts (such as regulators, motors, channels...) beside the glass

I got my acoustic glasses mounted. The glass must be mounted with care since it's fragile.
The wind noise is still present, but is way more reduced / refined.

I can confirm that only the glass is different, nothing else was needed for fitting the new windows.

Note, those acoustic glasses are marked with an A. Same goes with the windscreen (if i am not wrong, acoustic windshield is standard across A4 B9).
For more markings you can do a google image search with part numbers posted above.
