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.

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.

I can't get it to activate. Did you get it to work. I have 1700 miles and I'm following the directions and I cannot get it to work

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.
