Does anyone have problem with your transmission after updating software which makes the transmission upshift as much as it can? This causes slow throttle respond. When I want to accelerate immediately, it has some delay before revving up rpm. Is the problem going away in a couple of weeks like the BMW technician said so?
Please help. If the problem still exists even after a few weeks, I'll consider this car sucks after SW updating.
Thanks.

My car does the same. I don't mind it because it drives really relaxed. If you want better throttle response and higher rpms use the sportmode.

When they do a software update, the driver settings are deleted. So the transmission has to learn again. The car will learn how you drive and will set the shiftpoints, etc. So after driving a little bit it will get better.
My car did the same, and the mpg went down dramatically. But after driving it for a week everything was back to normal again.

Ahh thats what's happening.
Encountered the same problem with my previous E60 and always wondered what it was.
Thanks.

I went in for an emissions recall and delayed acceleration, came out with a vibration at 1500 rpm(Automatic) as if it shifts too early and lugs in the gear. The shop foreman said BMW is aware of the situation and will have a fix in software ver 15.2 this month.
