whew yea, what the forum needs is more witty comebacks like yours.

love, I am a car lover too but I feel EVERY CAR has its merits, even a Nissan Sentra. The M3 DKG/DCT is a marvelous piece of engineering, and I think the engine and tranny are a great match. Quick takeoffs from a standstill are not one of its strong points, however. That's based on what I've read on the forum, just like you.

Oh well... I thought my smilie metaphor was funny. I made myself laugh and that's all that matters when you're a self-centered useless troublemaking troll like I am!

Result: Really no LC.

So when you engage LC and get the checkered flag icon the clutch is "popped" and shifts are automatic ONLY when you keep the pedal floored (and then let the stick pop into its normal position from being held forward). If you hold the rpms at some other point (say 3500 rpm) and then let the stick go the car just takes of mostly normal with a slipping of the clutch.

So I was correct in thinking that LC wasn't working without the throttle floored.

Can someone explain "S6"? What is it if there are only 5 LED's?

If you have a M3 with M-DCT and do not know what S6 is you have not used LC and your credibility in general is really hurting. You have to get into S6 before using LC and you have to turn DSC off before having access to S6. Once you turn DSC off and then when in S modes you will see another hollow bar appear in the Drivelogic modes area.

P.S. The dash illumination is not LEDs, none of it.

Well, I have used LC several times...it never says S6 when I use it.So not sure what you mean...I guess I will

since yours is the only "answer" available. Cheers.

I am totally new to the dct and trying to educate myself before I order my M3, so please excuse my ignorance here. Anyway I am not understanding how this launch control hold the lever forward etc. is working. Say for example I am at a drag strip and wanna launch the car. Does it work like I have the clutch engaged and there is somethig I would release to make the car take off like dumping the clutch on a green light, or do I have the wrong perception? Any info is appreciated.

In launch mode, hold the DCT (shift) lever forward until the checkered flag appears on the dash. Mash the go pedal to the floor. Release the lever when you're ready to take off. Computer does the rest. (Or at least that's the way I understand it.)

All I can do is insist I am correct. THE ONLY way to get into LC mode is to BOTH have DSC off and be in S6. You could use your M button to have both of these settings stored. There is no way you can have used LC and not have used S6.

Uhhhh, the first (underlined) link is the one to download the full DCT owners manual.

DSC off= smoke. DSC on = not much. M mode = perfect. Launch control is great but for most street situation, just leave it in M mode and floor it.

The page is blank while it downloads the pdf file, at least on mine. It might take a minute or two. Try it again and let it sit for a few minutes.
