New Golf VI probelm

[wvg]

I need you guys advise.

I've got new golf 6 comfortline 3 weeks ago and very very happy with it.
However, there is a problem which I can't reproduce it again but it happens odd times so far 6-7 times. I am a software developer, sometime there is a bug but can't reproduce with same step. This is one of these kinds.

OK, here is the problem. When I change the gear to reverse or drive from revese position, and off the break pedal to accelate but car moved opposite direction(about 1-3 secs, if reverse position then goes forward, if drive position it goes backward). Initially, I thought it's because I was on the hill or sliding road but sometimes it happens on the flat road. Recently this morning when I wait to join the main road(drive postion and break), off the break petal then it goes backword.

I'm a dumb in mechnical things so please give some advise before I contact to my delear.
