Jolt forward when releasing brake

I almost just received a used Evoque Pure SD4 Auto, but while testing it out, I found out that when I'm stopped at traffic lights, when releasing the brake, the car just jolts forward. No errors show on the dash and the car's gearbox was just changed so no errors showed up at the mechanic's. I took it back and they said they'd look into it. Has anyone experienced this problem? Does anyone know what the problem is?
Thanks in advance.

Can't say I've heard of that one, but could just be some calibration needs tuning on the gearbox, hopefully they'll sort it for you.

I have the same problem with my SD4 prestige auto.
The trouble with diagnosing is that it doesn't happen that often.
It is quite disconcerting and annoying when it does happen though as it is quite a jolt.
I tend to put it in neutral when stopped in a queue or lights which seems to help.
