Surging idle issues? Dealer can't find any issues.
I brought this up a year ago or so with little response. At idle after the car(n20) is warmed up its has a small, but noticeable, constant vibration surge from the engine. It is not visible on the tach nor was it present when I got the car with 15k miles. It now has 44k miles
I know 4 cylinders vibrate more but this is a newer and not steady vibration. I also know the n20 has balance shafts to offset vibrations. This is the second time the dealer says there is nothing wrong.... Should I give up? I had a steering vibration issue with my e90 that I couldn't believe they wouldn't recognize and after 3 trips finally fixed. |

I've noticed a bit of roughness at idle lately on mine as well. I don't know, but I think it could be due to the current high temperatures combined with the heat generated by the turbos. My father has an Audi A4 2.0T and it is really bad.
Regardless, driveablity is not affected. It is very smooth otherwise. |
