Sitting in the passenger seat of my wife’s car, I was looking at the side window and I thought to myself the window looks awful, dirty, almost like there were circular spots on the glass. I took my camera out and took a picture of the glass with the window open slightly, and I didn’t see anything?? I then took a picture of the window glass with my sunglasses in front of my phone and got a picture of what I’m actually seeing with my glasses on. Is this a polarized effect or is this how the Audi glass is supposed to look thanks .

That is due to polarization on your lenses. It is picking up the heat treatment on the glass.
Put on non-polarized sunglasses, and you will not see that at all.

Take a look at MANY other vehicles with those polarized sunglasses on, and you will see all kinds of strange patterns on the windows.

Yeah, the polarized sunglasses are causing that to pick up. That's pretty common with those tints.
