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!

Summary of the thread

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.

Hi, I had similar problems with a 2007 BMW 3 Series (E91). In my case, the problem was solved by restarting the control units (disconnecting the battery for a minute)!

Thanks, thanks to this tip I was able to save my sat nav, which was constantly stuck. Could it be that my battery is getting old and should be replaced?

Great, with pleasure! The voltage is fine for me, I haven't replaced the battery yet and the problem hasn't returned.

I need the features of the BMW E46 1999 instrument panel programming when I change the instrument panel and Yanki parking

I have no issue with the scanner, just sometimes it doesn't clear codes with engine running, but doing for a couple of times it erases otherwise everything is ok!

Hello, Is it possible that the error code is currently present, i.e. static? If so, it may well be that the error code cannot be deleted until the error has been rectified.

Hello Brandon, Thank you for your feedback. As a rule, it is always better to keep the engine running during the readout process to ensure a stable power supply. Sometimes it can indeed happen that the error code can only be deleted the second time. However, if this happens more often in the future, please contact us again so that we can take a closer look ;) Regards
