Does Launch Control come standard with the M340i?
Is Launch Control standard on all 2020 340i models? Wondering if I have the option, and more importantly... if I do...How do I activate it! -Thanks!!

In the F30 it's Sport + mode, press down brake as hard as you can, floor accelerator and a checkered flag will pop up on your gauge cluster. Release brake and hold on for dear life!

Yes, but apparently there are rules to it
***Update*** - Found it in the user-manual - and YES< Launch control comes on all new M340i's.
***Launch Control*** *Concept* Launch control enables optimum acceleration on surfaces with good traction under dry surrounding conditions *General Information* The use of launch control causes premature component wear since this function represents a very heavy load for the vehicle Do not use Launch Control during the > break-in period (defined as Up to 1200 miles) for the Engine, transmission, and axle drive; 200 miles for the Tires, 300 miles for the brakes; with same break-in periods for any replaced components (brakes, tires, etc.) Do not steer the steering wheel when driving off with Launch Control *Functional requirements* Launch Control is available when the engine is at operating temperature. The engine is at operating temperature after an uninterrupted trip of at least 6 miles/10 km. *Start with launch control* 1. Switch on drive-ready state 2. Press the button. TRACTION is displayed in the instrument cluster and the indicator light for DSC OFF lights up. 3. Engage selector lever position S. 4. With the left foot, forcefully press down on the brake. 5. Press and hold down the accelerator pedal beyond the resistance point at the full throttle position, kick down. A flag symbol is displayed in the instrument cluster. 6. The starting engine speed adjusts. Within 3 seconds, release the break. *Repeated use during a trip* After Launch Control has been used, the transmission must cool down for approx. 5 minutes before Launch Control can be used again. Launch Control adjusts to the surrounding conditions, when used again. *After using Launch Control* To increase vehicle stability, activate DSC Dynamic Stability Control again as soon as possible. ___ I have yet to see it on my new M340i, but the story is it does exist - But supposedly, it only becomes available after a certain number of miles on the engine (to ensure the engine is 'broken in'), + certain number of miles driven in that day (to ensure the engine is warmed for the day). Then, and only then - the feature can be used as outlined above. I'd love to hear back if this understanding is incorrect. Last edited by BMW_Midlo_Man; 06-14-2019 at 11:02 AM..

sounds like standard launch control. LC with a AWD is typically very hard on the transmission, especially a torque convertor based auto. The brake torquing generates a lot of heat and, since there's practically no wheelspin, a lot of drivetrain shock too.

Is engine fully warm and are you pushing the accelerator all the way down until you feel the click?

Same here... 1800 miles. Only tried a few times under the conditions defined in the manual but did not work. I won’t keep trying until I fully understand why it won’t work. My research has yielded nothing except maybe I drove fewer than 6 miles when trying it.... but it was for sure at optimal temperature.

I have been using launch control (LC) since the day i got the car. Very easy to active. Used during spontaneous races from a stop light.
try this, Sport Plus Mode Transmission shifter moved to the right so its in S1 One press of the traction control button Press the brake to the floor Press the gas to the floor (not lightly but press the gas ALL THE WAY) it should show Launch Control Active in the gauge cluster. Let go of the brake. Works for me anytime i try this. if this doesn't work maybe some other factors at play. maybe the steering wheel is not straight or it's raining (rain sensor) or too cold. I am not sure if any of those things I listed actually affect Launch Control but just a thought.

Useful for personal runs. But not practical on the fly (at a light racing someone). 3 second limit a problem. Better solution Sport plus with traction transmission in Drive foot on brake rpm 2500. Of course this only applies to RWD. Also my car is lighter and faster so traction is a real problem.

The best way to get a feel for it is with the car OFF, press the accelerator down. You will feel a button just before the pedal hits the floor. That is what puts you into launch control mode. So when on, put in sport +, traction control off and transmission in S. Find a straight empty road.

1200 what? Miles? RPMs?
Been using LC since day 1 with about 80 miles on the car. Pretty sure you can’t dictate the rpm, you have to floor the gas and brake

Miles. The recommended break in period.

My rep said break in is only suggested for true //M vehicles, took him at his word and been driving the hell outta mine, guess we’ll find out if I start having issues
Edit: I see you have AWD and I’m on RWD so maybe there lies a difference in break in recommendations, not sure

Personally, I think there are few motors out there that truly benefit. And even from those, there's a small chance something actually goes wrong. That said, if it were it's doubtful it wouldn't be something covered under warranty. I've seen a couple of different recommendations in the manual - and yes one does state that break-in was only required for "M" vehicles. It was in a certain context though. On another page specifically dealing with break-in there was no specific mention of "M" vehicles, just a general what to do and what not to do during the 1,200 mile break in. From what I've seen - reality is for those vehicles that actually matter for break-in - usually you will find some electronic/software coded limitations that prevent you from actually damaging something until it's ready. Chevy even recently did this with their C8. I've seen this in other BMW's when the engine is cold the redline is lowered/controlled by software. I just don't worry about it anymore. Cars just aren't as fragile anymore, particularly BMW's. And the software used to control them are exceptionally good at protecting the engine. |

BMW still have a break-in regime for all engines, transmissions and driveline components. Longevity and efficiency being key reasons. Also why Launch Control is a "Do Not" in the break-in period. |

That said new cars don't need some voodoo break-in process these days. Just don't overstress the engine for the manufacturer recommended period of time and then you're golden. Premature stress could damage the engine a myriad of ways. Last edited by obscurehero; 12-28-2020 at 07:11 AM.. |

launch control has been a crap shoot for me. you'll eventually get the hang of using it consistently, but all i can say is make sure your tires are warmed up and the asphalt is hot because you'll leave rubber behind you. it seems like the car does better launch control on a slight upward street compared to a slight downhill... even the slightest.
