Hello, I have an A5 B9 3.0tdi and there is a weird humming noise when accelerating while turning. The noise occurs when turning either left or right. Anyone else have the same problem? I changed the rear differential fluid and brought the front tyres to the back but still no difference. Thank you in advance for any advice.

Yes- this happened to me and another guy, it's kind of like a grinding noise, like it's coming from wheel/driver seat area. Exacerbated by pavement that's grainy. For both of us it ended up being an object under the seat. Here's the thread. Please help! Can't identify this rattle - AudiWorld Forums

Thanks for your answer but mine is a different kind of noise. It comes from the rear wheels I believe and you can even hear it from the outside

Audi UK dropped the acoustic side windows are Jan '22. It's really poor practise. They bring out the face lift car and get all the reviews and comments on how quiet it is etc and then quietly drop it and still sell coz people think it's still as quiet as the reviews say.

I wish luxury brands would do the acoustic glass standard come on it’s such a small thing relatively speaking that easily gives points in the NVH dept. new model 3s get acoustic glass all around granted way more road noise then my Q5 has on less then smooth pavement but still at least the glass is there.
