Hope someone can help! Purchased a pre-owned 2005.5 3.2 A4 w/ sport package and 20k miles. Really love the car except a few things.... There is a noticeable hesitation from a dead stop making it virtually impossible to start smoothly from a stop sign or traffic light. I can't be the only one with this problem?? The dealer has been of little help. Any suggestions?

Also, the chrome strips around the side windows are all discolored. The dealer will not warranty it. Does anyone have the same issue and possible resolution.

Thanks.
