BMW 5 Series gearbox shifts hard after a software update, normal or not?
-
Maybe someone here has seen this before, because I am running out of ideas. I drive a 2016 BMW 530i and two weeks ago I took it in for a small service where they also did a software update on the car. Before that, the gearbox was smooth like butter. Since then, the shifts from first to second feel sharp, almost like a little kick from behind, and when I slow down for a roundabout it sometimes drops a gear with a bump. My wife noticed it too and asked if I hit something. I called the place that did the update and they said the car needs time to relearn how I drive and that it will settle in a few weeks. That could be true, but I have been driving two weeks already and I do not see much change. A friend who owns an X3 said that can happen, but he also said hard shifts should not be ignored for too long. So I spent an evening reading about how the gearbox and the computer work together and opened a page about BMW cars on a Sharjah website. It explained that the car learns shift points over time, and that old oil or a worn part can also make shifts rough, which made me realize the update might not be the only reason. A colleague then told me to look for Professional BMW automatic gearbox repair in Industrial Area 11 if the problem stays, and to ask for a scan before anyone opens anything. I like that advice, but I do not want to waste money if the car only needs time. My questions are these. How long does a BMW usually take to relearn after an update, days or weeks? Is there a way to reset the learned values, and can a normal garage do that? Should I change the gearbox oil as well, even though the car has about 85,000 kilometers and no records? And how do I tell the difference between a software habit and a real mechanical problem? If you had the same thing after an update, please tell me how it ended and roughly what it cost. Thanks a lot.
