Ok...this is just getting ridiculous....
I read on these forums a bunch of contradictory posts where people say they want a pure and fast sports car and how with the older cars they felt more part of the car feeling every raw part of the car and road...then in the next post they complain about scraping the front underside, rough ride, tire noise, smells, child seats, rear seats and a slight iddy bitty jerk when PDK is in auto sport/sport plus mode in stop and go traffic that causes them to jerk their wifey poo's neck and spill their grande mocha latte frapachino on the macadamia nut Crusted wood interior trim......GEEESH!

I reckon the issue is more about is this correct, or good, or useful, or intentional? And why? Was it designed as such to make the car seem more quirky and "sports-car"'ish or is it something that PAG and ZF should sort out?
FWIW, it doesn't really bother me that much, although I'm beginning to wonder more and more that maybe Sport and above is not really intended for normal driving. The more I get used to normal auto, that's kinda what I think it was designed for: smooth, in city driving. And it certainly isn't sluggish or slow or unfulfilling. I think PDK, being new, takes a good bit of getting used to, especially with SC: 6 different ways to drive the car and all of them probably have a purpose or design intent.
I started out just automatically pushing Sport...'cause I want the car to go, right (old habit from driving BMWs?
). Now I'm thinking maybe that is a simplistic naive approach.
However, I still have to wonder in Sport/Auto - why that behavior? Is it good for something? Did the designers have something in mind that most of us just aren't getting? Seems like a fair question.

Steve: Standard autos do not engage 1st when the car stops. The PDK does, and that is why this happens, in my view. Normal mode probably feathers the clutches a bit longer and Sport/Sport Plus less, for performance sake. If enough complain, PAG may change the PDK code and soften the Sport/Sport Plus shift to 1st... but is that what one wants when driving through a tight fast 1st gear hairpin?

I wonder if Porsche could use the speed sensor and program PDK in Sport mode to either:
1- shift to neutral going from 2nd slowing down to a stop and then once the car is stopped it would shift to 1st.
2- shift to 1st only once the car is stopped...basically delay the shift to 1st longer.
This would not effect any one track activity like going into a tight 20mph hair pin.

Exactly!

Probably just my simple mind -- but when I think of all the very complex things that PDK can do, it just seems silly that this cannot be solved via software programming.
I also don't see how it made it through beta testing with real world drivers. Maybe they never hit a stop light?
Last thing, if PDK is to be the future for Panamera, Cayenne, etc., just imagine how much crying there is going to be in the near future...

Took my 2009 4s to the dealer today to demonstrate the "abrupt" stop issue to the service advsior. Very nice discussion, but feedback is it is a nature of the beast and there is currently no software update available for this symptom or anything else. I agree with one of the previous contributors who made the point we should all provide feedback to Porsche direct and through the dealers. It shouldn't be that difficult to fix. One blemish on an otherwise amazing vehicle. I would be interested in hearing from other drivers who do not have this issue(IF THERE ARE ANY?) to see if there is some determing factor that might help the rest of us. Advisor also thought it might get better with time - my car only has 300km.

Wow, did you type that in one breath?

Again though, today, I purposely stayed away from sport and the car is a blast to drive. And that's a good thing since otherwise a car without SC would be crap, and I just don't believe that is true.

I don't mind the jerk. It's a friendly love tap from your P-car

In auto is different. As I speculated, if one is in auto on a tight hairpin, one might want the auto mode to engage a 1st. 'First' downshifts are always jerky even when done properly manually.

I suspect that in manual Sport/S+ it just stalls, opens the clutch (Neutral) as it stops. The 1st is engaged after stopping. It would be up to the driver (in manual) to engage a 1st.

Just like smoking a habit of having cup of coffee at 7am while driving is very difficult to change. And I would gladly cut out entire section in center panel where ashtray sits and installed there one nice deep cup holder, just like one in my wife`s honda accord. And I am almost completely serious here, believe you or not.
