I had the service done before 1200 miles and as expected, could not get the flag immediately after the service. I was only able to get the flag after I passed approx. 1250 miles. This was consistent with many others who had their service done before 1250 miles and could not get the flag until they had passed 1250 on the odometer.
Whether a service indicator light would preclude the flag from coming on, I don't know that for sure, but in this case I don't think that's the issue, because a) He is getting the flag, just not functionality after that, and b) I would assume he would have noticed by now, and mentioned, that he has a service indicator light that was not cleared. In any case, to get the flag, you must be past 1250 miles. |

1. Came to a complete stop and took my foot off the brake. 2. DSC off then shift mode to S6. 3. Shift lever forward until flag appeared. 4. Full throttle (without pushing through the detent) RPM went up to 5.5k and when I let go of the shift lever, nothing happened and the RPM went to idle. I then repeated the process, this time with the throttle pushed through the indent and it launched as it should. This detent has to continue to be pushed throughout the entire process if you want the transmission to shift for you, otherwise, if you lift off the detent after you've launched, you are then in effect back in normal S6 mode, which means when you get to red line, the transmission will not shift on it's own and you will bounce off the limter. Bottom line... it's all about the detent. Last edited by MysticBlue; 05-28-2010 at 10:03 AM.. |

There is a detent at the bottom of the throttle travel, kind of like the kickdown on an automatic transmission. Push the throttle all the way, then push a little harder and you feel a little click. Don't know if "detent" is the right word to use, but that's the best I can do as far as describing it.

Doing launch controls won't void your warranty on the clutches BUT........
I sold my '04 E46 M3 with SMG to a friend two years ago. Last month, the car with only 25,000 miles but 6 years old had clutch troubles. I never used the launch control. Well the dealer checked and sure enough no LC's were recorded on the car. Because of that fact they replaced all the clutch components free of charge as a courtesy fix, since the car had only 25K miles and had not been abused. So I suppose if your clutches die at under 50K miles but over 4 years old or over 50K miles but under 4 years old, not doing too many LC's may save you some money down the road. The SMG bill was around $2500, and I'll bet it's a lot more for DCT. |

^ sounds like your buddy got lucky that it was a courtesy fix..
bmw would NEVER put launch control on a car if it will void your warranty! it's part of the damn M experience. Thats why this car costs double the price of a regular 3 series. Granted I still haven't done the damn launch control cause I can't get the damn flag to pop up. But I think what I'm doing wrong is pressing the brake pedal. I will try again tomorrow... but this voiding warranty is non sense. What is the dealership going to say. "umm sir sorry your dct is messed up, but its your fault for using LC too much." gimme a break. It comes standard w/ the car, its not like LC is a form of tuning or kit thats purchased aftermarket. if my cd player goes out on the car is it because I played to many cd's or listened to too much music, therefore I wore out the player faster and due to that reason it will void my warranty?... |

e93 dealer manual on LC
Here is what the manual says on LC. I will try it later this week (both the manual version and what this forum is saying) and report back.
Launch Control Launch Control enables an optimum acceleration when starting off on a road surface with good traction. Do not use Launch Control too often; otherwise, the powerful stresses on the vehicle will lead to premature component wear.< Launch Control is available when the engine is at operating temperature, i.e. after driving continuously for approx. 6.2 miles/10 km. 1. With the engine running, step on the brake with your left foot. 2. Activate Dynamic Traction Control (DTC), refer to page 90. 3. Activate Driving dynamics control, refer to page 62. 4. With the vehicle stationary, activate the manual mode and select 1st gear. 5. With your right foot, push the accelerator pedal past the resistance point. The engine speed for pulling away is adjusted. A flag symbol appears in the instrument cluster. 6. When you release the brake pedal, the vehicle accelerates. Keep the accelerator pedal floored. 7. The upshifting occurs automatically as long as you keep the accelerator pedal pressed past the resistance point. Launch Control will be ready for use again after you drive a certain distance. Launch Control is not available for use during the break-in phase, refer to page 126. To maintain driving stability, keep DSC activated whenever possible.< |

Too many drivers stress that their Launch Control doesnt work/come up.
Just persever a little and you will see how easy it is to activaite it. You will then say to yourself....that was sooooo easy, i cant believe thats all you need to do!

activating LC on the Z4 is so much easier... and you don't have to be on a completely flat surface like you do on the M.
I hate how if it rolls slightly the M won't launch... it's rare to find a completely flat place around here with the Z4, you put it on Sport+, M1, hold brake, push throttle, release brake and hold on.

You're keeping the gas pedal floored? Letting up on it, even slightly, can cause it to disengage too.

I can't get mine in LC mode either, tried 4/5 times last week in the end I gave up!
I see from some replies not to apply the brake but the manual says apply the brake?Or am I reading incorrectly? Really want to use this at least once! Last time I tried I ended up wheel spinning for what felt like miles!!

It says to press brake...but then a couple steps later...it says something along the lines of "with the vehicle stationary". I'm guessing they thought that implied to remove your foot from the brake...since...why wouldnt it be stationary if your foot was on the brake? Definitely something they could of made a little clearer.
