I drove a beautiful '13 S6 this week. I will buy this car if someone can figure out the hesitation from stop issue. It would drive me batty.

It is clear to me that this a major design flaw. Audi BS'd me and told me there was nothing wrong. I still complained. Then they told me that others had complained and they had a fix. No fix. The only way around it is an ECU fix but my understanding is that could cause you to lose your warranty. Any other comments?

 

Are you referring to the turbo lag? I got the APR ECU re map and I drive in sport mode. No hesitation now. Drive awesome.
