M3 DCT questions

So ... as I've posted before, I'm waiting on my 2012 M3 to arrive. I ordered the DCT, and have some questions about how it works, compared to VW GTi DSG.

So, with the GTi DSG, I have three modes:
1. "Drive" - basically acts like an automatic
2. "Sport" - again, like an auto, but holds revs, increases throttle responsiveness, etc
3. "Manual" - I'm control of gearchanges, drives like a manual

For (1) and (2), I *can* change up and down using the paddles, and the car will take control again after 30 secs of no activity on the paddles.

So ... with the M3, I've been reading the manual...and to be honest, it's not completely clear to me...

It seems to have "Drive" and "Sequential" ... from what I can make out, "Drive" is equivalent to the DSG mode (1) above, to all intents and purposes drives like an automatic ... and by dialling in the drive program, you can make it seem more like DSG mode (2).

Then, "Sequential" mode is fully manual, more like DSG mode (3) above, where you have complete control of the gear selection.

Is that a fair understanding??

I'm sorry to be blunt. But that is NOT how it is AT ALL. I'm on my iPhone and hard to type the whole thing for you but I suggest to download the manual from BMW website and read it.

There is D and S, D is fully automatic and S is fully manual. S mode will NOT downshift or upshift for you unless you come to a stop and then it will downshift only to prevent stalling the engine.

Each D and S mode has drivelogic settings 1-6, 6 only available when traction control is completely turned off. Drivelogic controls the sift agressiveness of the DCT.

Just saw that you are reading the manual. I guess where your post is confusing is the comparison you are making to your VW.

I am pretty sure, once you use the paddles to either downshift or upshift from "D" mode, it won't go back, but it will stay in Manual mode.

Hey e1000 ... appreciate the response!

With DCT, if I'm in D mode and a change gear with the paddles, I understand that the gearbox goes into S mode. Is that right? And if so, does the car eventually re-take control and move back into D mode, or will it remain in S mode until I change back to D mode?

it won't retake control until you move it back to auto mode.

It will not change back unless you tell it to. The easiest way I found to do this is the use the M button and set it for S mode. So as you're driving in D, you can hit the M button to get you into S mode, then when you hit the M button again to come off of M-mode, it will place you back to D.
