guarantee that's the issue

if I remember I think the torque converter disconnects at idle on the E90, so when you don't use your parking brake the car may be just like leaving it in neutral (don't quote me on that) maybe try pushing your car after you park it and put it in park and see if it rolls

most normal automatics don't do that so lots of auto drivers don't use their parking brakes and are just fine.
