having this problem with my 06 A3 in the past 2 weeks. i have no problem starting the car. runs fine on roads and highways. only after a traffic stop, it hesitates and shudders a little when accelerate. sometimes it even shuts off and the battery light would come on. i would then turn the ignition off and turn it back on again. anyone here experienced this and know what the root of the problem is?

thanks in advance!
