Hey Guys - I was just sitting at idle this am and all the sudden I felt the car start to feel like it was misfiring.

the EPC light came on and when I started driving it felt like the car was in some kind of limp mode (maybe 10% power available).

I pulled out the VAGCOM and got this.

I reset the codes and the car was fine for about 20 mins. Then the exact same thing happened again. Any idea what to start looking at in the troubleshooting process?
