To help de-mist in the mornings (and not just rely on the front demister control) I wind my windows down slightly.
However, I've discovered that, in doing so, the window emits a sound similar to bubble wrap being popped. So, going down a road, with literally every bump / surface imperfection it will make a tapping / popping sound. Once it's opened a bit more the noise stops.
The passenger side is exactly the same, so it is not faulty assembly but a "feature". My dealer said the same. They road tested a customer car and replicated the noise.
Of course, with ACC and with it being winter this is not a huge deal, but in spring / summer I'll find it an annoyance. And can't believe this wasn't picked up during endurance testing!
Photo attached (shows the amount window has to be open when noise is heard + my finger shows the exact point where the tapping occurs if pressed).
Does anyone else have the same?
