I have also just started experiencing this issue while trying to leave my neighborhood at a stop sign. I am going to contact my service center about this hesitation.

Well.
Here’s something for you all.
I had a moan at my dealership about this, especially as the car is 2 years and 11 months old… the end of warranty check seemed a great time to have a bit of a moan.
Obviously the tech couldn’t replicate the issue, because isn’t that always the way! They called and told me the good news and I pushed back a little after reading on here about throttle control issues so they went back and spent a bit of time re-searching,
Then as if by magic I got a call to advice that they think they had identified the issue… it’s a software problem
Yes I know you’ve just rolled your eyes too. But… wait for it… there’s a PuMA measure!
“B48C & B48D - Jerk during drive off after engine start”
It’s new! It was circulated to their systems on the 09th May!
Typically, there’s still no fix. Awaiting an update apparently. But is down to the DME/ECU.
Im just trying to get some paperwork and I’ll update!

That is good news that they are aware of the issue and good be fixing it. I missed my appointment.
Hey. Further I’ve obtained the following info from a snapshot of the printed sheet the tech had;
I couldn’t see the bottom bit of the page but I think that was it, basically no fix but highlights a DME issue causing jerky engine pull away. The tech said it didn’t 100% match the symptoms I mentioned as the complaint description appears more mild but anticipated that might be them playing it down so thinks it’s the same thing.
Also under vehicles affected, I couldn’t see the first inch as his finger was in the way!

Interesting, but It doesn’t match the observations in my Zupra either. I’ve had the hesitation occur twice on the same drive too. and this report also looks to be related to the B48 variants and not the B58 models.
Fingers crossed if it does fix things for your car.

You know I didn’t even click that this was all the B48 engines when I read it or posted. Well spotted
I have a similar problem with my M40i (B58 engine). It happens about once a month. It starts immediately after starting the engine and only the first seconds when driving off. After that, it continues to happen during the complete ride (only when driving off). To stop it from happening I have to turn off the engine for about 3 minutes. I've already been to the BMW dealer. They hoped that the software update from the end of 2021 would help to solve the problem. Not a known problem at my dealer and no data logs. After reading this forum I will go back to the dealer again. Apparently I'm not the only one with the problem. I'll keep you informed when I know more.
Hi,
I have seen this problem discussed on another forum (regarding the B58 and ZF gearbox but not the Z4).
As the running gear is the same this MAY be relevant.
The consensus elsewhere seems to be gearbox related; not fuel or throttle. Software, specifically.
May help, but I don't know.

Could you share a link to the discussion? Thanks!
