Mini Cooper Fault Messages and System Failures

Alright, I'm officially pulling my hair out. My 2020 Mini Cooper is throwing the weirdest fault messages. It's got sporadic errors in driving mode, and sometimes the malfunction indicator lamp lights up. Systems like the audio and navigation are failing out of nowhere. Sometimes control units even shut down temporarily or become unresponsive. I saw a warning light flash once too. Of course, there's an error stored in the error memory. Any ideas?

Whoa, that sounds frustrating! I had something similar happen in my Mini. Check engine light would come on out of nowhere, and the radio would just die sometimes. Even the navigation went bonkers once. Did you try checking the battery? Sometimes a weak battery can cause weird electrical issues.

Interesting. I haven't checked the battery specifically, but I did run engine diagnostics and there was an error stored in the memory. What do you mean by 'navigation went bonkers'? What exactly happened? And did your warning signal come up?

Yeah, by 'navigation went bonkers,' I mean it would show me driving in a field when I was clearly on the highway. And yes, the warning signal definitely popped up. Honestly, it sounds like you might have a bigger problem than just the battery. I'd suggest taking it to a workshop and having them check the BUS system connections. That's what fixed it for me.

Just wanted to follow up. Took your advice and brought it in. They found a defective cable connection to the BUS system, just like you said! Cost me about 155€, but everything is working perfectly now. No more warning lights, and all the systems are back online. Thanks again for the help!
