Default C7 automatic - surge at start

I have noticed this multiple times but always forget to catch it on camera. When I remote start my 2016 Z, the car actually moves forward even though in park with brake set. This video shows it but it has been much more pronounced at other times. Anyhow - this happen to everyone with an A8 when remote starting?

Thanks!

Maybe torque converter unlocking when fluid starts flowing?

Are you on some hill or slope. Moving forward after putting in Park is nothing more that the tranny get locked up in torque as the weight of the car is being held by the transmission. If your car moves forward or backward when you put it in park and then take your foot off the brake, you should be setting the parking brake before you take your foot off the brake pedal. You're using "Park" in the transmission to act like a parking brake.
