Plug & Play? What else is needed to make the Kufatec work?

Don't have to be in Dynamic, as long as the transmission is on S. As the matter of fact, my drive select is always in dynamic. I do change the shifter to D or S according to driving situations. Start/Stop will kick in if the shifter is at D even drive select is still in Dynamic.

Thank you guys for clearing my doubt. I never use dynamic except when I tried launch control a few times. That's why I wasn't sure.

Have you test driven any competitors with start-stop systems? Certainly compared to the MB C300 and the Infiniti Q50 2.0T, the Audi start-stop system is much, much smoother when it restarts the engine...

(... not sure why that would be. Maybe something to do with the DSG transmission vs a torque converter auto? or a smoother starter?)

Nope, this will not work on the A4 B9.

Yup. Of all the 2.0l I've driven, our A4 has the smoothest start stop system. My BMW shakes much more. But yes. My 3.0l doesn't shake as much when it starts up. It is very smooth in fact. Only downside is that it shuts down a bit too early in my 3.0.

I test drove the Mercedes C Class and found the start stop in that car was better, it didn't have the "shudder" I feel with the A4.

Is there any tips on getting the shudder reduced when the car is started in the A4? Do I just have to use start-stop more often to break it in, or perhaps the engine needs to be nice and warm.

Nope. I found the shudder to be the same back then and now. In fact, I think the shudder may have slightly increased compared to when it was brand new. Or maybe it's just that I'm used to the zero shudder of my A7 and then when I drive the A4, the shudder is amplified?

I've seen options in OBD11 to disable. The problem is that the options exist in different sections and I don't know which one (if not both) need to be changed and to what exact value.
