Not to thread jack BUT lol. When did it rattle just under cold starts or? Does it in any way mimic the issue mine is having?

2013 S4 45k miles, (currently) stock tune, intake and x pipe r only modifications.

Short version of the story...After the VVT TSB was done at dealer (under warranty) now no longer under warranty, I noticed a faint rattle coming from the driver side firewall were the steering stem comes thru. It's only bet roughly 2500-3000 RPM. Sounds like an exhaust leak or chain rattle.

Only makes the noise under load. When stationary revving in neutral does not make the noise. Even putting car in neutral coasting and free revving motor, noise goes away.

I replaced the drivers side flex pipe bec the Audi tech claimed it was leaking, but it was not (shocker I know)

I took a video to help describe the noise:

Any advice would be greatly appreciated!
