I've just got an 07' S3 Black with Black optic and Black/Silver leather indoors. I love the car but am experiencing a problem. When down shifting from 3rd gear to 2nd and releasing the clutch i've found the car starts to shudder sounding like its about to stall. This only happens going from 3rd to 2nd. I'm thinking this is a fault with my car only and not an S3 trait. Hopefully something that can be fixed under the warranty. Can anyone advise??
