So I have an AUQ 1.8T and when I got it I didn’t know due to the sound dampening from the air box but when I changed to an induction kit I noticed that it was fluttering. I have found out the issue is there is no vacuum for the recirc valve which is OEM. I haven’t noticed a significant lack of power but I haven’t been able to figure out what has caused the vacuum line to not work. I have taken it to a couple garages and they don’t know either so any suggestions are welcome!
