Just doesn't happen. I get the same delay on takeoff from dead stop. Not good enough for a car company that supposedly has performance in mind. Even my humble Nissan Rogue auto is more responsive off the line and overtaking (of course it ultimately has less power, but at least initially it gets moving more quickly and predictably)...

Did a quick search on F30/F32 forum for similar problems and found the B48 engine and 8AT (ZF) also had similar problems.
https://f30.bimmerpost.com/forums/sh...ht=smooth+stop From what I can tell, it's a torque converter lock-up issue that appears to be "normal" for BMWs. |

I think it’s all programming. If it’s happening across platforms and with dct, aisin, and zf trans then it’s not a mechanical problem.

Now we're stuck since we want to replace the E91 with an F31 or possibly X2 M35i or even an X3/X4 M40i. I've even read in a number of reviews of the X3M and X4M about delay at slow speeds which is being blamed on the S58 when of course it's probably a similar programming issue (to meet max fuel economy and min emission numbers). Bold statement: "There will be no "fix" for this "problem"." I say that since it's probable the car would require EPA emission and fuel economy re-certification. I'm not sure what level of tweaks they can do without re-cert. That said, I know on the E9x M3 there were a number of DME updates for the S65 that didn't require such, but then again that was a decade ago now. Hence I would love to be completely wrong about this and BMW releases updates for all these models that provides smooth and responsive on-demand engine/transmission response in these slow-speed situations.

If the platform becomes popular there will be aftermarket tunes

Yeah, I also think a reflash is unlikely. I wonder about improved settings in iDrive or something to allow for selection of attributes and whether that would essentially also be impossible because it violates the regs for economy, etc. After using Cobb's Accessport and Dinan flashes to make previous vehicles just simply drive better, I'd be very happy to do it again. However, it seems like flash tunes are getting more rare and everybody is going piggyback, which doesn't appeal to me as much. At least being on this forum I know I'll find out as soon as anyone discovers some kind of fix...

This is the touchiest throttle of any BMW I have owned. In Comfort, as discussed, there is a slight lag. In Sport, I need to have thin soled shoes to modulate the pedal accurately. The other morning I was wearing boots and at a stop. A slight press on the pedal and I almost rear ended the car in front the acceleration was so instantaneous. This car really has a blast of power down low.

I also noticed that you need to press the TCS button (just once, not hold) to activate dynamic traction. Otherwise, 1st and 2nd gear get limited power output if it senses any slipping. Car feels so held back.

Yes it's a little bit useful in the snow when getting out of some side streets. If you do hold it down it turns off all the nannies and you can go have yourself some real fun in the parking lot doing donuts

So my quest continues for a replacement for the E91. After driving an M-sport package X1 and being totally disappointed, we've now shifted gears to potentially a Macan. I've yet to drive the latest Macan S yet, but I thought this quote below from R&T's test was "interesting" given the discussions I've seen in this thread and also comments made on the X3M/X4M board and reviews about these slow speed response issues.
After heavily praising the Porsche PDK, they point out: " I did determine one situation where the V6 and PDK didn't quite play nice: When in rolling to a near stop heading towards a roundabout, in Normal mode, the transmission won't downshift to first. In second gear at low speeds, there's a moment where you get on the gas and nothing happens. It's frustrating, though I imagine it could be solved with some software programming. And otherwise, the transmission is top-notch." In this case, it sounds like a manual downshift into 1st or using one of the sport modes would solve the issue, and the throttle would respond fine. I'm not sure that's the case in the X2 M35i all the time? (or X4M with similar complaint?) If you're coming to a slow (10-15mph?) rolling corner, say a 90 degree turn at a green stoplight, and you demand response with a moderate dose of throttle, is the problem still apparent if you've already manually downshifted to 1st? Will the transmission respond and accept the downshift request quickly? And will the throttle respond linearly and smoothly? Waiting for the new year to test drive everything in this segment to see first hand what's up with all of these potential issues (X2 M35i, X4 M40i, X4M, Macan S, Macan turbo). Has anyone had any success with BMWNA yet on the throttle issue?

I don't see it
maybe it's my driving style, I really don't see or experience the throttle issues. I drive almost exclusively in sport mode and I rarely use the paddles. what lag I experience is very similar to my former 2013 335, stick. there I shifted
I really like my car wish it had Android auto and blind spot warning (it would make Mrs. rounderman happier, but she likes the car overall) I grin when i get in it. definitely try the m35, is it perfect, of course not, but a good mix of fun and practical. enjoy the hunt |

As far as a solution, I wish BMW could replace comfort mode with a 'de-tuned' version of sport mode + softer suspension if DDC option was installed. Sport mode is way too crazy for inner city driving. While comfort mode is so weak that Corollas are beating me off the line. |

At this point, the only thing that might motivate BMW to fix this problem ASAP is for potential customers such as yourself to point out this issue and then walk away. Best of luck! |

I drive in comfort on occasion, I read a long time ago that Jackie Stewart was quoted in an article to drive like you have an egg under your foot. Having said that I really don't see any significant lag again maybe its how I drive I try very hard not to put myself in situations where 1/2 second matters (the joys of being older). On the stiffness side it is my understanding you can have sport mode to only do throttle and not suspension. I have the DDC but the child in me likes the stiffer ride I assume you have seen the threads on the pedal tuners, the folks who have installed them, seem to really like the performance. Given these are drive by wire programing seems a smart solution to your issues I truly hope you can get the car working the way you would like. Good Luck |
