PDK Shifts rough in automatic sport mode
Had software upate on 2009 911 4S but did not fix the abrupt/rough/jerky behaviour just before stopping - from 2 to 1. Dealer has given up. Porsche says it is not a warranty service issue - e.g. nature of the beast. Frustrating that it issue is intermittent/random - why you can stop three times in a row perfectly and the next 2 are rough makes no sense. Any solutions people can share?

I have found three things in my case that are perhaps coincident with avoiding the "jerk"/"lurch" ...(a) manual down shift into stops with final brake, or (b) there is a point as the car is downshifting on its own where you very lightly brake (complete feel/experience thing), or (c) drive the car with higher rather than lower revs even though you are in auto (forced shifting); brake normally. While doing any of these I don't have the problem.

I had this 2-1 shift thing with my car for the first 2500 miles or so, then suddenly it went away and I cannot make it happen no matter how hard I try. I don't know if the dealer did some update when they added my MF Wheel or it was just a matter of breaking it in. Seriously, what once was so obvious is now completely gone. I know my driving style has not adapted to it that much that it's me making it not happen. Complete mystery.
