2016 A4 B9 2.0 TDI QUATTRO
Has anyone else had an issue with a rattle coming from the brake light at the top of the rear windscreen? It only happens at certain frequencies in a song or when the car is nearing a gear change (auto). After some trial and error I can replicate the issue by playing a ~67Hz frequency through the speakers (B&O). I’ve taken it off and there’s no rattle when shaking it. Ive also tried running foam around the edge but it’s still rattling like crazy when around the above frequency. I begrudge replacing the unit without knowing it will definitely fix the issue. Any advice would be appreciated, I’m going crazy with it!
