PDK shock/thud in 7th gear when lifting off throttle
Hi, I am new to this forum and new to Porsche.. I took a test drive of a used 2010 911 Turbo (CPO) with PDK. the car shifts smoothly in normal and sport mode but when its on 7th gear (on highway), i noticed when i slightly lift off the throttle, it would make a shock/thud noise and you can feel the car shocks(lurch?) forward. its as if it was a split second disengaging and reengaging the clutch in a rough way.. is this normal?
I had driven a 2014 Cayman S with PDK before and it does not do such things..

I've not driven a 997 Turbo and I've only spent a few minutes -- not enough time really -- in a PDK equipped car, but I can tell you that under some conditions my 996 Turbo 6-speed can manifest a bit of a lurch or a jerk in the higher gears, mainly 5th and 6th.
The behavior is only really noticeable because it is so out of character for the car.
What I have attributed this to is the boost coming on or going away under fairly light and partial throttle operation. I have had the boost "gage" visible on the dash and have observed boost on and boost off concurrent with the car's behavior so I'm pretty confident that is what is going on.
Just to be sure though you need to test drive another (or several if you can swing it) 997 Turbo and see if this behavior appears in these cars too.
