F30 launch control does not work hlep

Hey, i've got 15' LCi f30 d

Sport automatic is coded,
Launch control is active (checked on bimmercode)
(I can see also Launch control in instruction)


But it doesnt not work...
Engine is hot enough, ~ working over 20 min
sport plus mode, transmission on D/S, hardly on break and acceleration to kick down button...Tried few times - not working

Any ideas what is wrong ?

It's very picky about what you do to get launch control to work. You have to have been driving for quite a bit, I believe 10 miles with car at operating temp. Then sport plus, shifter to the left, but not in manual, left foot HARD on the brake, right foot to the floor passed the kickdown, and you should get the launch control flag. It won't work with DTC fully off.

Its difficult to grasp how to do it at first but you hold that brake hard all the way down then hold the gas all the way down. think of it like your trying to press the gas down as fast as you can without the car recognizing it's being pressed. that's the easiest way i can explain it.

sounds like you have everything else coded correctly, may just be the execution

Well, I tried to push the gas all the way down, even to 3k rpm - nothing happens

Tried on sport plus, on ordinary sport with turning dtc off myself (both ways - quick press, long press )
Ofc transmission in sport mode in all cases (pushed to the left)
Followed also instruction but its the same as all told before

On the youtube vid i saw they just pushing the gas pedal to the max and letting it very quickly, car even didn't reach 2k rmp and "launch control flag" appear on dashboard.

I am little afraid to "test" it so often...without result. Hope nothin happens with the transmission or other parts

Strange...
