Same problem … Can you please tell me size of big and small so I buy the same aftermarket? Thanks for usefull video clip you made, greetings from Belgrade 😁
I recently bought a Q7 and it was the same on the passenger side. I'll assume the surround degrades over time. My A6 Bose subwoofer on the driver's door is now rattling so I can only guess it's the same issue.
