Mild vibration and idle sound

I've got a 2010 S4 (around 60K miles).
Both videos are after driving 20 miles (warmed up) and with 93 octane on board.

Does this idle sound normal?
Is the vibration (on the hose) normal at idle?

Any insight would be appreciated!

Thanks.

Get an OBD2 scanner and see if you get a fault code for ignition coil(s). You'll need a VAGcom tool and software to properly reset it. Coils are cheap.

I have same issue

I have an A6 prestige 2015 mine doesn’t sound that much the engine but it shakes when the car not move i brought it to the Audi and they said that was the fuel injectors. After they fixed the injectors the car still have same problem and they found out that it was the camshaft that was broken on bank 2.
