Light vibration/jerk on idle when engine is cold

[acemow]

Hi Everybody,

My car is a 2013/1.4 TSI 160hp scirocco with dsg at 7500 km. Whenever I start the engine when it is cold (e.g. in the morning) there is a slight vibration per 3-4 seconds (I know high sound and rpm is ok, my situation differs), after engine temp goes to 90C vibration goes minimal but I still feel it on traffic lights. Dealer in my country says this is normal with TSI engine, following you will find the video of vibration problem; " onclick="window.open(this.href);return false; so do you think it is normal? do you have same vibration/jerk at idle?

Is is just me or is the RPM a bit hig at first?

Could be misfiring when cold?

thanks for the sheet I wasn't aware of this. actually when engine was not cold one of my friend plugged diagnostic tool that shows no misfire on any cylinder, do you think I should plug it while engine is cold or this diagnosis was enough?
