using Mobil fully sync 5-30 and 76 premium 91 gas. WOT maybe once a week, not extremely often. The vibration only exist during idle (~800 rpm). slightly raising the rpm would stop the vibration.

Vibration started about 3 months ago. I've changed spark plugs thinking that was the cause of the issue but vibration is still happening after installing new plugs.

Default May be misfire from coil packs

I have a shudder during idle. I remember reading about a similar situation in eurotuner, where they ended up replacing the coil packs. I watched the misfire counters on my VAG and sure enough, cylinder 2 would count up on every shudder. I haven't tried putting the new coil pack in yet, though.
