My '05 M# is in for it's 12k service. Launch mode failed, my sone loves it, so I requested it be repaird. Dealer states it is no longer supported due to wear on the clutch. Anyone know about this? :bawling:

IANAL but you *could* try to argue that feature was part of the car when you bought it (it was) and to deactivate it now is breach of contract. A Software "Bait and Switch".

It "failed" ?

Just stomping the gas pedal has more or less the same effect anyway.

A Software "Bait and Switch".But it's not a feature they market nor even mention in sales literature. It's not in the manual either. BMW could argue that the M3 doesn't have that feature explicitly.

Yup, that's what I think, as well. The discovery of launch control was pretty much an easter egg ... an undocumentated (and unmarketed) feature of the car. I wonder if BMW is updating the software to delete launch control as M3's roll in for regular servicing.

I'll get more info when I pick it up. I tried to get the dealer to load the Euro oftware but it was a no go. They told me if a serive light comes on they will need to reload the Us software before working on it and the light will go out. It may also reset my mileage to service and cause me problems with the 100k service agreeement. Who knows. Love the car anyhow. They put me in a 330 loaner. Boy am I glad I passed on that dog, by comparison.

Is there some mode like 'S1' to 'S6' that can control that stuff? Is that just for the SMGs right (I think it is)

Launch is for SMGs only. S6 only comes on with DSC off. I'll play with it more. Strange it stopped working however.

How, exactly, did it fail? You turn DSC off, select S6, push the shift lever forward, and press down on the throttle. What happens?

Actually it IS mentioned in literature from BMW, but it is called Acceleration Assist.

Actually it IS mentioned in literature from BMW, but it is called Acceleration Assist.In recent U.S. (BMW NA) literature? Definitely not in anything that came with my car, nor the 2005 US brochure.

Terry, In the literature I have it is refered to as "Acceleration Boost".

You're right.

Here is the page. Idiot software will not upload a 768x1024 image, only a 1024x768. :dunno:

Here, I used a different piece of idiot software to rotate the image :rofl:

Did you get it at 1024x768? I was not willing to reduce the image resolution because Vb software is too stupid to realize taht a 1024x768 and a 768x1024 image are the same bloody size. :)

No, I had to resize it after I rotated it. You are right, the VBulletin software is pretty stupid. The height and width are hard limits that you are not allowed to exceed :nono:

I have the Pilot Sport Cup tires on my 2004 M3 Coupe and I tried launch control for the first time....with only 1800-1900 rpms to work with (3500-3600 Euro version), the car just bogs down and barely takes off. It's much better and easier to just stomp the pedal which will bring up about 3500 rpm clutch drop.

It seems to me if the launch control feature has stopped because of clutch wear, then the car/clutch has been abused. In Europe, they say launch control will work 30 times before the clutch needs replacing. I can't imagine anyone needing to use launch control 30 times. It's not like the car is slow by just flooring the gas pedal.

I would get the clutch replaced and get launch control working again so your son can get back to street racing.

that is likely urban mythology.
I know people who have used their LC more that 100 times and still have the OEM clutch.
It has not been stopped/supressed in any form that I know of.

That last note in the document could explain and legally justify BMW's decision of not supporting this feature anymore...

Well, since the feature was never supposed to be in US models, they could possibly remove it. But it was there, and well known to be there. It would be an interesting fight.

Only thing is, that will not support them from removing it, but only from providing warranty or maintenance agreement service due to "abuse". But then again since they put the feature if, how does using a feature included by the manufacturer work as abuse? :)

There is a blurb in the run-in section saying not to use launch control during the break-in period..
