Engine Idle Surges from 750RPM to 1000RPM

[57Strat]

While sitting at a red light with the car in gear (“D”) with the engine at normal operating temperature, the engine idle RPM will randomly increase from 750RPM to 1000RPM causing the car to move forward.

The car is a 2008 E92 w/ DCT. Has anyone else seen this problem? If so, is there a known solution?

That's no a malfunction. The car has a built in "walking speed" that gets activated by either lightly touching the throttle, the car drifting forward in a slope or backward in a slope. Also if you don't completely bring the car to a full stop and holding the break down for few seconds the "walking speed" takes over. Also if you recently changed your settings to a sportier one.
