2023 Audi S5 — buzzing noise only at one engine RPM

Owner notes beat generic advice here. On the 2023 Audi S5 in Orlando, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “buzzing noise only at one engine rpm,” that was the fork that mattered for me. Post the numbers (or the code) and people can get more specific. This is the filter I use when the thread starts repeating itself. That's my plan before I call anyone.

I'd keep this practical. Verify the cheap/easy branch on the 2023 Audi S5 before a big repair or a big spend. That's where I'd start. This is from a 2023 Audi S5 in Orlando with 46,000 miles. Stop there until you know. Doing the boring step first on purpose.

Don't overfit one forum story to your car. If it still isn't clear on the 2023 Audi S5, a specialist hour can be cheaper than another round of parts. I'd do that before spending real money. Any freeze-frame data saved? If the story changes I'll post the new data.
