So I’ve been noticing at lower RPMs while slowly accelerating that there is now a strange secondary whistling sound that sounds like I’m driving a M6 with straight cut gears. Almost sounds like a supercharger whine. Am I crazy or what? I’ve never noticed this sound before…Anyone ever run into issues with their A10?

Since I’ve owned the car annoying things like this keep popping up. First was the throttle body plate scratching sound which got fixed when I upgraded the throttle body to a Soler TB

Then it’s the annoying wastegate rattle

Now this 🙄

Video coming tomorrow

I have an A10 in my 5BW and it’s quiet. You in a 4BW, so not sure if maybe something being transferred from your V6 and turbos? No issues at all with mine and love my beast.

Good luck in finding out what is causing the noise and sorry to hear that you had some issues.

It was a failing transmission pump

The wastegate rattle has made its way into these cars???? You gotta be kidding me. My ATS V had that and it sounded like I was dragging pop cans behind the car. What did the dealer do to fix it??
