Audi s4 2019 Exhaust Valves

Hello everyone!

I've been having issues with the classic rattle noise coming from the exhaust, but then stops once the valves are opened.

I was thinking about unplugging them to keep them open, but have a few questions.

  1. Since the valves automatically close when turning the car off, how do I open the valve before unplugging it?

  2. Is there a valve box on both mufflers?

Thanks in advance!!
