Completed the survey. 13k miles on C2S PDK. No noticeable stumble so far.

 

Thx Mad max.

It would be very helpful if other non-stumblers took 2 minutes to complete the survey and help their fellow brethren get to the bottom of this issue.

Data is key.

Thanks again.

 

Currently at 1,600 miles. Smoothest shifting car I have ever driven. No stumble issues to report.

 

Thanks for taking part in the poll, but could you also please complete the brief survey is located at; http://www.sogosurvey.com/k/RQsRVUSWsRsPsPsP

Thanks

 

I just took an extensive drive focused on light/moderate acceleration from 2000 to 3000 rpm and steady state driving near 2500 rpm. No stumble/hesitation/vibration. Nothing. Normal, Sport, Sport+, no difference. All gears, no difference. PSE on/off, no difference.

2012 C2S 7MT SC PSE, 4100 miles. Build 03/12.

Filled out the survey. Good luck to those that have this.

Given that this issue has happened in every Porsche model since Vario-Cam was introduced, but only to a small percentage of each iteration, I'm going to say data is NOT the key and this is a purely random fault.

 

Survey completed

 

Much appreciated.
I hope our other brethren will also be as generous with their time.
