It's like in the old days with carburetors and a huge "flat spot" in the response. Mash it and nothing for a few beats and then... vroom. In this case it's clearly a programming choice.

Did an experiment yesterday: applied periodical pushes to pedal, wavelike action like push and release but quickly, push and again release quickly, no any reaction from car at all as a result, no rev increase, gear change, not even an attempt, like you doing nothing.

Maybe throttle mapping like some have stated.

I agree. But sometimes I find sport mode very busy for day-to-day driving. You basically cannot drive and relax. Let owners of m40's or pure M's forgive and criticise that 28i cannot be very busy. It's great to have fun but it is basically always provoked driving.
Spent couple of days in Efficient, maybe just me, but lag is less annoying there and you are getting nice saving millage numbers on instruments cluster (... getting older).
Workaround for Personal mode when moving is to use Boost mode with holding left shifter. Not that it is quicker but it is at least predictable, if you go this way you know what to expect with what delay v.s. just floor the accelerator in Personal mode and rely on mood of car whether it wants to react or not.

I agree, sport mode is a bit too aggressive for me for day to day driving, especially on the freeway. Great for having fun but not practical since it uses much more gas. I usually stay in personal mode, and flip the shifter from D to S when I need instant throttle response, and then back to D when I know I won’t have to stop anytime soon.

Do you know how to do D->S and back S->D via paddle shifters? Not sure manual is clear or of this is possible.

Just pull the gear selector backwards to change from D to S and again to switch from S to D?

Yep, thanks I know this. The question was about is it possible to achieve the same with paddle shifters not to leave steering wheel.

Is it safe to change from D to S and back when the car is moving?

Yes.

As far as I know, I’m personal mode, using the paddles will shift it into manual shift mode, but will revert back to auto after not shifting for a while.

Today my transmission partially(?) shit itself haha.
I seem to have on and off issues where we'll be driving on the freeway and the car would seem to downshift and felt like it would get "stuck" in between gears and rev really high, but immediately correct itself and have no issues after. Today something similar happened but I immediately got an error on my dash that told me to take it to the service center and that my reverse gear didn't work. I pulled over and tried to reverse and it felt like it was sitting in neutral and just revving/not moving. I restarted my car and same thing. I took it to the dealer and they took it in, but when they started it up reverse worked fine. They still have it to diagnose. I just find it alarming and odd that this would happen. I took delivery of the vehicle in December and it only has about 2700 miles on it. I'm curious if anyone's had any issues similar or if this has happened to anyone else! (And/or using this as a cautionary tale)

I just stumbled upon your thread and wanted to check in on how your car has been doing? I currently have my 2023 X1 at the dealership where it's been for the past two months due to a similar issue. My baby was at 7k miles.

It only happened once while I was driving where I was sitting at a red light, tried to go on green, and the car didn't want to budge at first. When it finally went a few seconds later, there was a loud screeching sound and thudding around the front of the car, and then it finally went all the way. It happened a few more times while I was on the highway, but it finally stopped and became smooth again after like three times. Scariest moment of my life especially since I had passengers!

There have also been a lot of times where when I'm stopped for a prolonged period of time, like at a red light, and there'd be a thudding sound from the front of the car that sounds like something dropped. This was pretty frequent to almost every day I was driving.

I finally asked the dealership to take a look when I took it in for service, and they also said it was transmission-related. However, the first transmission BMW sent was unable to be programmed with the car. The second transmission came this week and they're working on it, but boy am I scared for any issues coming from this.

So, how's your car been treating you now?

I have similar issue with my 2024 M35i. There's some clunking noise coming from the DCT (could be the front differential) when the car is in stationary or approaching to a stop (both reverse and forward), and the noise did not appear in the first 1000km. Brought the car back to the dealership today and hopefully they could replicate the issue and get it fixed asap.

I actually did a manufacturer buy back. In the previous car they had to install a whole new transmission but I wasn't sure if I'd trust the car since it happened to me 3x or more after taking it to get fixed 3x. I'm in a 24 x1 now and it's been much much muuuuch better and I wonder if the super jerkiness that some people experience from the get go is indicative of this issue. My new 24 drove seamlessly from the start and even my start stop wasn't as invasive/laggy. Like I don't mind driving with it on now vs I couldn't drive without turning it off before. Granted I'm only at 2k miles now but this is around when the first time I ran into the issue with the 23, so I guess I'll report back if anything happens here with the 24!

I hope that everything works out with your car! I never had a loud thud or anything, I just would lose power and become very jerky or I couldn't reverse.

Please keep us posted on this, experienced similar issues with transmission, my dealer responded that the car is operating as intended.
