Electronics problems with the 2018 BMW 2 Series petrol engine: sat nav failure and warning lights

Hello everyone, I have a few problems with my 2018 BMW 2 Series gasoline engine, which now has 27790 km on it. The electronics have recently started to go haywire, my sat nav sometimes won't start at all or only after a while. And sometimes a warning light comes on in the speedometer. Have any of you had similar problems and can tell me how they were solved by your mechanic? My last visit to the garage wasn't that great, so I'd better ask here before I go there again. Thanks in advance!

The conversation revolves around a 2018 BMW 2 Series petrol engine experiencing electronic issues, including a malfunctioning sat nav and warning lights on the speedometer. Possible causes suggested include faulty communication between control units, problems in the vehicle electrical system, and voltage fluctuations in the battery. Solutions proposed range from extensive troubleshooting and repair at a factory, to a simple reset of the control units by disconnecting the battery. A software update was also suggested as a potential fix for the sat nav issue.

This issue could be related to a weak battery or poor battery connections. I recommend starting by checking the battery voltage to ensure it's fully charged and inspecting the battery terminals for any corrosion or loose connections. If the battery and connections are fine, the starter motor or its connections might need to be checked. Please keep us updated on your progress.
