2018 S5 convertible. No noise when turning on even surfaces. It is not a u-joint kind of noise. It feels more like a body/chassis thing.

When turning left or right into an incline such as a parking lot, certain drive-throughs, etc. there is a "popping" noise as the car twists. Do all A5/S5 Cabriolets do this? Is this just a design flaw where the car is not stiff enough in a torsional type maneuver that it makes noise under stress or is there something wrong with my particular vehicle?

Has anyone else experienced this?

Thanks!
