Electrical Chaos in my Delica, Need Expert Help!

Hey there, I had a similar nightmare with my 2009 Mitsubishi Delica D:5 last summer. The symptoms were exactly like yours, nav system completely dead, unusual warning lights popping up, and weird electrical glitches everywhere. Took it to three different shops before finding someone who actually knew what they were doing. Turned out the Engine Control Unit (ECU) was failing. The problem wasn't just coding, the unit itself was faulty and needed replacement. This was pretty serious since the ECU controls basically everything electronic in the car. The fix involved replacing the ECU and reprogramming the new unit. Spent about two days at the garage because they had to get everything properly synchronized. It's not something your average mechanic can handle, you need someone with proper diagnostic equipment and experience with Mitsubishi electrical systems. If you're in this situation, I'd strongly suggest going to a Mitsubishi specialist. Regular mechanics often struggle with these specific electrical issues. Hope this helps.

Thanks so much for sharing your experience! That's really helpful, seems like we had pretty much the same problem. Would you mind telling me how much the ECU replacement and reprogramming ended up costing you? Also, has everything been working smoothly since the fix, or have you run into any other electrical gremlins?

Hey again! Happy to update you! Yes, after getting it fixed at the specialist, everything's been running perfectly fine, no more electrical gremlins haunting my Delica! The faulty control unit was definitely the culprit, and once they sorted out that incorrect coding, all those crazy warning lights and system failures disappeared. The total bill came to 1000€, not cheap, I know, but worth every penny considering how well it's running now. Been about 8 months since the fix, and I haven't had a single electrical issue. The nav system's working like new, no more unusual warning lights, and all the electrical systems are behaving exactly as they should. Honestly, finding a proper Mitsubishi specialist made all the difference. They knew exactly what they were looking for and fixed it right the first time. Sometimes you've just got to bite the bullet and pay for proper expertise, you know? Let me know if you end up getting yours fixed, would be interesting to hear if your experience is similar to mine!

Thanks again for all the details! Just got back from the mechanic today actually. Followed your advice and took it to a Mitsubishi specialist, turns out you were spot on about the ECU! Mine ended up costing around 1200€ with all the programming and labor, but honestly, it was worth it. The mechanic really knew his stuff and explained everything clearly. Had to leave the car there for three days, but now it's running like a dream. All those annoying warning lights are gone, nav system's back to life, and everything's working perfectly. It's such a relief to have this sorted finally! Much better than bouncing between regular mechanics who were just guessing at the problem. Guess sometimes you really do get what you pay for. Thanks again for pointing me in the right direction, you saved me a lot of headaches! Will definitely stick with this specialist for any future issues.
