435i Kickdown button vs. Left paddle hold
Hello all! Thank you for helping me figure out some of my confusions in the other thread. There is one question lingering that I can't seem to find an answer to, so hopefully by separating this thread future searchers can more easily find the answer. For the record I have a 2016 435i GC, but I am guessing this is relevant to any similar 2016 vintage with the SAT.
It appears that there are two modes for rapidly downshifting to zoom away when in auto (D or M/S auto):
The manual does not describe a difference between D and M/S in auto mode nor does it describe different behavior between driving modes. My take--and what I am looking to clarify or confirm--is the following:
Being in M/S Manual mode appears to be different, and I'm not discussing that. It seems well documented that kickdown + one left paddle in M/S manual mode will drop gears to the lowest. My question is what happens in D or M/S Auto. Manual description of kickdown, which doesn't say much: Quote:
Manual description of gear selection using paddle. Note #3: Quote:

Update: the hold left paddle either doesn't work or in every instance only one gear down was the "lowest possible gear."

I don't think just holding the left paddle does anything except shift one gear lower. I think you have to be holding the paddle in conjunction with pressing past the kick down point for it to shift more than one gear at a time. I don't know how this changes in different driving modes though or whether it is different in D or DS/Manual mode.

Do intend to try that. Was hoping someone here could explain the difference. My understanding is the kickdown switch itself works fine. The manual doesn't say anything about the combo when in D or M/S manual. Shrugs. |

The user manual is specific that the paddle block change option does not work in D mode. I do wonder if it is the same in M/S, if you attempt a change with the paddle with the first paddle movement. I've not got the feature in my car so can't try the possible options. HighlandPete |

Cruising along at 45 in 6th gear, M/S, Sport (+), holding the - paddle downshifts one gear and one gear only. Nothing else. No magic. |

I see the opposite of what you're describing; namely, holding the gas down to the floor doesn't do anything. A quick flick of the left paddle downshifts immediately, but holding it down for about 1.5s will downshift to the lowest possible gear, even if I don't touch the gas. I do this often when approaching an intersection, since otherwise the car would be happy to continue lugging out in 5th/6th gear (but acceleration would be lackadaisical). As I approach, I hold down the paddle, instantly shift to 2nd, and accelerate out like a boss.

We're also supposed to be able to hold the right paddle shifter in to go from M to D mode when you have pushed a paddle to go into M mode and want to go back into normal D mode, and don't want to wait the 10 sec or so for it to auto switch back to D, or manually switch the shifter to the left to S and then back to D again (tedious method...)

The left-paddle-hold works in conjunction with the kickdown when in Manual shift mode, I think?
(i.e. kickdown and hold left paddle to shift into lowest available gear when in Manual). That's how it works on my F10 and how it worked when I test drove an F30... Holding down the paddle w/o kickdown did nothing. |

I think the issue is "respective transmission" without defining what that transmission is. Someone here pointed out it could be a European feature not applicable but not noted as such. I can confirm that 2/3 bullets noted in my paste from the manual above regarding the shifter do not work.

I have SAT. Only kickdown switch actually kicks down more than a single gear under any circumstances. Left paddle hold is always ineffective.

You guys are really making this more complicated than it is.
Using left paddle is just like rev matching with a manual. Your speed won't really increase because the amount of throttle hasn't changed. When using "kick down" you're now asking the transmission to select the lowest gear based on the increased throttle (ie more fuel) That's it in a nutshell.

Left paddle did not result in lowest possible gear (either while accelerating or while braking) in any possible combination. Comfort, Sport, Sport+ & either D, S-mode, or M-mode. Perhaps the manual is talking about a feature of the DCT for the M's and it found its way in all manuals?

I have no idea since I haven't even seen where that citation is actually from it's just been mentioned a couple times.
On another note one of these things also said that in D mode and you change to MX by hitting a Paddle up or down, if you don't want to wait the 10s until it resets to D automatically or do a quick flip to S/M and back to D, it mentioned holding the right paddle will set back to D instantly. I tried this today along with the left paddle again, and yet again neither of these proposed functions work on my 2013 ZF8. I hope someone can provide a source for these functions.
