Strange vibrations during starting the car with foot on the brake and pushing the start button occationally there is a jerky motion, just for a second.
Have duplicated the problem for the mechanic but the dealer were unable to fix it, just discussing the problem and not going any further.
Brought the car three time.
Anybody are having or experiencing the same problems?
Have owned and driven five different Audis.
Thank you.

The slight jerk at start up you feel is common and has been discussed extensively in the forums. It appears it may be the drive train taking up a bit of slack. Happens occaisionally to me as well but not all the time. Not sure about the "strange" vibrations - perhaps you could provide more detail. Are the RPMs fluctuating? How long does it last, etc.?

Could be a spark plug on it's way out. One cylinder not firing as fast as the others.

I have a slight jerk when I put it in gear usually rear first backing out of garage. I think there is no trasmission mount in this car which may explain this. I also have vibrations at idle when warm, but not cold that I can't explain. New air filter, new plugs, new passenger mount. It's not horrible but noticeable enough which I do not recall before.

There is a transmission mount in all the C7's. You can buy an appliance to stiffen it up for crisper shifts.
