This vibration occurs once the car drops to the low idle (just under 1k). The shaking that is shown in the video is transferred to the cabin as a subtle thumping noise and noticeable rumble. The vibration can be felt in the seats and stick. Has anyone experienced this before? Dampener pulley maybe? Any help/suggestions would be greatly appreciated!

Does it stop when in park? Or is this what u mean when the car drops to low idle on cold start?

I have the exact same noise and vibration... when sitting at a red light i can actually see my passenger seat shake. I've read that it can be a clogged PCV. Going to change my this week! ill let you know if it changes anything

No CEL? if you have a scanner can check for pending codes. Does it go away when you start driving ?

Same exact thing here! I can see the seat shake. I also go through a lot of oil, so that might be it.

No CEL. No codes last time I scanned. It goes away if I'm not at idle.

When it drops to low idle after the cold start.

Mine does the same thing after it drops below 1k RPM after cold start, I can see my passenger seat shake when at a stop, Audi dealership said it's normal, been doing it for 2 years, quit caring about it.

yup, i got the CEL after 2 years of driving, says I need to change my breather hose. There's a TSB for it, my mechanic gave it to me, but i can't find it anymore. Once i get my hands on it ill post it up here

I haven't looked into carbon buildup. Would that cause it?

Brought my car in finally, and it was one of the breather hoses on the back left side of the supercharged that was tangled with another vacuum hose. The two vacuum hoses were squeezing agasint each other, causing the CEL to go on and off. Still feel a slight shake in the vehicle. Must be another issue then...
