Z4 Door Opens When Driving?

No that shouldn't happen. 
I went around a corner on two wheels once, in my youth. When the company Cavilier I was driving came back down on four wheels, the rear nearside passenger door opened. I closed it and it never happend again. May have just been the shock of the thump. But I would probably get it looked over.

The doors will unlock if a collision is detected, but should not unlatch and swing open, it's linked to the battery cut-off and airbags ets so doubt that's your problem. More likely the lock mechanism is jamming either being worn, gummed up or this time of year has some damp and frozen inside. I'd flush the mechanism with carb or brake cleaner solvent which dissolve muck and drives out damp, then lubricate with graphite or lithium spray. Although we've all done it it's best to avoid WD40, oils or traditional grease if possible as they collect muck and go gummy.
Also have a look at the strike plate, is it loose or showing signs of unusual wear? Wear notching and grooves on the strike bar/pin indicate that it or the lock mechanism are worn and may need adjusting at the strike plate or replacing. Also check if the door is dropping due to worn hinge pins which can prevent proper shutting.
Let us know how it goes
