Launch control seems inconsistent...

So I follow the normal procedure... let the engine warm up over a few miles, sport+ mode, push gear stick to the left for sport mode/manual mode, press firm on the brakes with left foot and accelerator with right good for around 2000rpm, and yet the "launch ready" icon on the dash has only showed up 2 out of the 4 times I've done it.

Am I missing something?

Are you hard down on both pedals? The flag only stays for about 3 seconds.

Is the engine actually hot though? If it isn't up to full operating temperature, launch control is locked out.

They also advise to allow a cool down period of 5 mins in between launches.

From the manual: "Launch control is available when the engine is warmed up, that is, after uninterrupted driving of at least 6 miles/10km."

Aside from that: 8AT into S (not manual), enable "traction mode" (one short press of the DSC button), left foot brake to the floor, right foot throttle to the floor past the kickdown point.

Works every time once the car is warm (to BMW's definition) and when this process is followed.
