I'm definitely in the same boat as you guys. When driving at slow speeds in second gear, the car just seems really jerky. I mean I understand why, because the car cannot predict when I'm going to accelerate or brake thus it needs to control the clutch engagement and disengagement.
For example, If I'm driving at 15mph in traffic speeds, the car hesitates whether it should put the clutch in or out which I think is the problem thus causing the "clank".
Also even when I'm driving in S3 mode (or any in fact) and approaching a stop sign in second gear, the car lurches forward slightly on the aggressive side which I don't like.
I have to keep bugging my dealer in order to get that software update. If not, maybe I'll contact EAS on pricing to have it done.
