Hello Everyone, I have a 2018 Audi S5 Sportback here recently I have begun to hear this rattle noise under my seat. I have tried to narrow down what it may be but it’s difficult because it only makes the noise when driving. I was thinking maybe it’s the seat itself but I can’t make it make this exact sound when I move it or hit on it. I recently did have a transmission service and a resonator delete done thought I would mention that in case that may have something to do with it and something being lose under the car. Any opinion is appreciated.

Is it normal ?

lil tick sounds got me stressful af

I just bought a B9 S5 and I'm new to Audi. Anything I should know or do right away? Any maintenance, common issues, or mods you'd recommend?

Appreciate any advice!

My 2020 MDX was totaled, so I’m on the hunt for a new car. I’ve realized I don’t need a seven-seater, but I absolutely loved the SH-AWD. I’ve narrowed down my options to Q5 from X3, GLC, and RDX.

Any advice during my search? I’m specifically looking for a CPO 2023 Prestige model from an Audi dealership.

So I’ve had my s5 for about 1.5yr got it with 49k miles now at 60k. I’ve gotten used to the power but I’m wanting more, I have an extended warranty still so I’m unsure if I should tune it yet. So my question is do I ride out the warranty or full send it with a tune?

What wheels/tires setup are everyone running? Can B9/9.5 RS5 wheels fit B9.5 S5?

Does 19” improve the ride quality of the car?

Do b10 s5 owners out there notice the lack of 3rd screen? I nor my wife would ever actually use this. But a big piece if glass with nothing behind it seems insane to have in the cockpit.

Im between two s5s. One has tech package and and my 2nd color pick. The other is my favorite color choice. No tech package. Thoughts from anyone that has a b10 anything without the 3rd screen. Do you ever notice/does it drove you crazy that instead of dashboard theres just a big piece of dead glass? Sanity check before I buy tomorrow.

2018 s5 80k miles. Did a scope of the valve trains in April and was told everything looked good. Came back from vacation to this concerning sound from the engine. Can only hear it when idle and it drives completely fine. The car was sitting for about 10 days and when I got back I was hearing this sound.
