HI NOUNOON
hello!
I am also new to th forum and glad to see the same feathers!
I also drives a 2015 porsche bolster which had the same issue-it got resolved by changing the coils though…please ask your service technicians to interchange the coils and see if the coil is the real culprit.you might get error code and the system also allows you to drive.when you swap the coils between misfired cylinders and running cylinders, the error coding must show the shift to previously running cylinders….then its confirmed the issue is with the ignition coils…i did this exercise and confirmed about the coils and got it changed and the issue was resolved.all the best and happy motoring!
