BMW Xenon Lights Turning Purple? Fix These Signal Issues

Hey there, I can relate. Had a similar issue with my 2005 BMW 5 series last winter. The lighting system was going crazy, and I got those same warning messages. After taking it to the garage, turned out the xenon ballasts were failing, and there was a loose connection in the main wiring harness near the headlight assembly. The ballast replacement wasn't a huge deal, but the wiring issue was more serious since it could've caused a short circuit. The mechanic said moisture had gotten into the connectors over time, causing corrosion. They had to clean the connections and replace some damaged wires. Total repair took about 4 hours. Not the cheapest fix, but definitely worth it for safety. My lights have been working perfectly since then, no more purple tint or warning messages. Just make sure whoever works on it knows their way around BMW electrical systems. The wiring can be tricky on these models. Hope this helps!

Hey, yeah I remember reading your post! I had almost the same issue with my 2008 3 series. They also had to replace my ballasts and fix some corroded wiring. Just curious, do you remember roughly how much you ended up paying for everything? And has everything been running smoothly since the repair? No new electrical gremlins popping up?

Hey again! Glad I can follow up. Actually, my car's been running like a charm since those repairs, especially that turn signal issue you asked about. Just got it fixed last week actually. The mechanic found it was just a dodgy cable connection that needed sorting out, cost me 95 Euro, which wasn't too bad considering I was worried it might be something major! As for the earlier repairs we discussed, yeah, everything's still working perfectly since getting those ballasts and wiring sorted. The xenon lights are back to their bright white color (no more weird purple tint), and all those annoying warning messages have disappeared. I'd say my total bill back then was around 800 Euro including parts and labor. Might sound steep, but honestly, it was worth every penny for the peace of mind. These BMWs can be finicky with their electronics, but once you get them sorted properly, they're solid. Haven't had a single electrical issue pop up since those repairs. Just make sure you're going to someone who really knows their BMW systems, makes all the difference! Let me know how yours works out after the repairs. Always good to share experiences with these cars!

Thanks for the detailed follow-up! Just wanted to update you on my situation. Finally got my BMW fixed yesterday after finding a really good mechanic through a. You were spot on about the ballasts! They found the same issue, faulty ballasts and some nasty corrosion in the wiring. The repair took about 5 hours total. Cost me around 750 bucks including parts and labor. The mechanic was super thorough and even showed me the corroded parts they replaced. Honestly, such a relief to have it properly fixed! The lights are back to their bright white color, and those annoying dash warnings are finally gone. The mechanic also gave me some tips about keeping the connections dry to prevent future corrosion. Definitely feeling more confident about the car now. Sometimes you just need to find the right mechanic for the job, you know? Thanks again for sharing your experience, really helped me know what to expect!
