DCT Modes? M/S?
Hi.
I have hopefully bought a Z4 35is today, wee Coming from 2 Z4 M Coupés I thought it would be fun to try something new. But hey, the DCT is confusing...or not? D = Drive, that I understand But what are the differences between M/S? Are both manual? I drove it today but can't remember how the gearbox worked because I had thousand other things to think about Thanks! /Filip

M/S are both activated by tossing the lever to the left. S mode changes shift points for the gears in "automatic" mode. M is when you start shifting for yourself with either the levers or the paddles. In M you can shift when you like up to redline. It changes for you at redline, or when you come to a stop.
Congratulations! |

DCT details
Great reply from Bobmos!
I would just add that moving the shifter to the left puts you in total control so don't think it is going to shift up for you. If you ever need to shift but the wheel paddles are difficult to catch while steering as in very tight turns, remember a quick pull or push on the shifter might be easier. (holding it left) And BTW I have heard that it is the same 7 speed DCT found in the Ferrari 430 and 458. After spending half my life heel and toe, double clutching various worn out transmission synchros I have become lazy and usually leave it to the quicker and smarter DCT in D, especially in traffic. Some other notes: The Sport and sport + buttons also hold the transmission in lower gears in D. Normal tries for economy. Sport + will shift more firmly if you want a to hear a tire chirp. Wish you the best with the E89 |

Not incorrect
Of course it shifts down to neutral or first gear when you stop or go too slow. When would you want to purposely stall the car? There is no clutch pedal. By the same token it probably upshifts at red line or has a rev limiter or both.. You do have full control plus it is fool proof. It also will not let you shift to a gear that will cause over revving in that gear. Bad things can happen very quickly otherwise, when all it takes is an inadvertant touch of a paddle or button.

Another question:
When you go to S-Mode and click a paddle or the shifter is goes to Manual mode right? Can you go back to S-mode from M-mode or do you first have to go to D then S?

You can use the paddle shifters either D or S-mode. The only difference being while in D mode, after shifting manually, the transmission will slip back into auto mode after a few seconds, while in S-mode, you maintain control until you nudge the shifter back into D. So, in other words, if you just need to accelerate a little bit to get pass a car or merge, you can quickly downshift with the paddles while in D mode, and the transmission will revert back to D mode after a few seconds.
To get back into S-mode from M-mode, you have to go to D first, then nudge the shifter into S. No other way around it. |

Flick the shifter to the right and then quickly back to the left to exit M and go back to S.

Not trivial at all esp since the events happen often. I don't want OP to get confused because as much as I'm a DCT proponent, we don't have total control by flicking the lever to the left, doesn't matter in S or M mode. The computer overrides in certain conditions. It could've been programmed to exactly mimmick the MT but this DCT does not.

Manual cars - how many people money shift and destroy something? The DCT programming won't allow us to destroy anything and who wants to drive past redline on purpose? Not a manual feature I want I know you are just being clear that there is still computer stuff going on unlike a true manual, but these things don't get in the way of anything important. |

Yes, ofc DCT is great because it avoids blowing the engine but I'm just pointing out that there's no total control, that's all. |
