DCT: N to 1 while slowly rolling?

Maybe I'm just being stupid, but occasionally I accidentally pop into N while sitting at a stoplight, but slowly rolling forward, and then I try to get back into 1 and it won't let me until I hit the brakes and stop completely, making me look like a dumbass who just stalled.

What's the best thing to do in this scenario? Surely rolling along slowly isn't much different than being completely stopped, but the car won't let me do what I want

to prevent this from happening any further, do not put it in N when at a stoplight...use N for parking

Yeah... it's accidental, I guess I'm just getting used to it.

But that reminds me, how the hell do you get this transmission in park without turning off the engine?

It's not an auto. You don't put a manual in "park" when the engine is running. Treat it like a manual. If the engine is running and you want it not to roll, either keep your foot on the brake or use the parking brake, just like a manual. The only reason it has a "park" function is because it takes hydraulic pressure to keep the clutch engaged, therefore, unlike a manual, when the engine is shut off, keeping a gear engaged won't keep the car from rolling.
BTW, if you are rolling fast enough, it will go from N to 1st. I live on a hill and when I first leave my house I often pull out of my driveway in reverse and pop into N then just let the car roll down the hill. After it's rolling, I pop it into 1st, without putting the brakes on. If you're rolling fast enough, it will actually go straight into 2nd. If you aren't rolling fast enough and you have to put the brakes on, learn to just brush the brakes as you put it into gear. That is enough to allow it to go into first without actually coming to a complete stop.

It will get into 1 even if the car is rolling (i.e. not at a complete stop) if you sort of step on the brake enough so that the car is still rolling but the sensor senses that you've applied the brake.

You don't, that's what the ebrake/parking brake is for.

You can go into gear from neutral at any speed. The computer will select the highest gear available for the speed you're going without bogging down the engine. You can also select neutral at any speed as long as your foot is off the gas.

Knock it off. The car is essentially in N when you're stopped and the brake pedal is depressed anyway.

I was just thinking in terms of slow rolling from or near a stop, but you are correct, it will go into gear from N at any speed and will select the correct, highest gear when it does. I should have made it more clear.

Yep. Great way to put it in N while at (whatever) speed when a <put your favorite punk car you enjoy taking to school here> is nearby and throttle the engine to let'em know who's the boss.

Thats not strictly true..the car is still in gear with both clutches disengaged.
Getrag advise leaving the car in gear when stopped at traffic lites etc.
The OP just needs to get out of the habit of knocking it into neutral.

How??? In a DCT, you can't get it to N while moving.

True, but like the OP I find that at low speeds it won't go to from neutral back to gear at low speed without a little brake. In contrast, as you and Mystic point out, it will happily go from neutral back to gear at higher speeds without the brake. I have always wondered what BMW's reasoning is for making it behave this way. Maybe if the preferred gear for the current speed is 1st gear, it always requires brake? Edit that theory can't be true - Mystic says he goes from N to 1 with no brake when leaving his home.

One thing you can try is to let the car roll along in 1st gear at engine-idle speed. It moves pretty slow. I agree with you though - it would be nice to just be able to do that, and also be able pop it in and out of neutral as you need to in order to regulate speed. I sometimes do this with the 335i 6MT, so it would be nice to do the same with the M3 DCT.

You can even at higher speeds. Just hold the stick to the left and hold it for 2 seconds.
