BMW X2 Electrical Chaos: Dashboard & Light System Mayhem

Had a similar situation with my 2019 BMW X4. The symptoms you're describing match what I experienced, dashboard warnings, funky turn signals, and color-shifting headlights. Took it to the garage last month at 95,000 KM. Turned out the main wiring harness had some corroded connections, and one of the xenon ballasts was failing. The ballast issue wasn't super serious, but the wiring harness problems needed immediate attention since it was affecting multiple systems. Mechanic found that moisture had gotten into one of the main connector plugs, causing the corrosion. They had to replace the harness section and reseal all the connections. The xenon ballast was a separate fix, but they did both at the same time. Not a catastrophic problem, but definitely not something you want to ignore. These electrical gremlins can spread to other systems if left unchecked. Get it checked soon, these symptoms usually don't fix themselves.

Thanks for sharing your experience! That's really helpful as it sounds exactly like what I'm dealing with. My symptoms are identical, and it's good to know it might be the wiring harness, definitely makes sense with all these electrical issues popping up at once. I'm curious though, do you remember roughly how much you ended up paying for both fixes? And has everything been working properly since the repair, or have you noticed any other electrical quirks?

Hey there! Happy to give you an update. Since I got my X4 fixed last month, everything's running like a charm. The whole turn signal issue is completely sorted, no more weird behavior at all. The repair turned out to be simpler than expected, just needed to fix a dodgy cable connection that was causing all the drama. Total bill came to 95€, which wasn't too bad considering how annoying the problem was. Much cheaper than I initially feared when I thought it might be the entire wiring harness! Haven't noticed any other electrical quirks since the fix. The dashboard's clear of warning lights, and all the signals are working perfectly now. Honestly, it's such a relief to have it sorted. Definitely worth getting it checked out when these things pop up, sometimes it's a much simpler fix than you'd expect. Let me know if you end up getting yours looked at. Curious to hear if it's the same issue!

Just wanted to update everyone! Finally got my X2 checked out yesterday after reading about your experiences. The mechanic I found was actually great, super thorough and explained everything. Turns out it wasn't quite as bad as I feared. Had a similar issue with corroded connections, but thankfully didn't need a full harness replacement. The mechanic cleaned up the connections, replaced a faulty ballast for the xenon lights, and added some extra weatherproofing to prevent future moisture problems. Paid about 120€ for everything, including labor. A bit more than what you paid, but still way better than I expected. The best part? All the warning lights are gone, turn signals work perfectly, and my headlights are back to their normal color. Really appreciate everyone's input, helped me understand what I was dealing with and gave me the push I needed to get it fixed before it got worse. Car's running beautifully now!
