Black Smoke & DPF Woes: Galant Diesel Needs Help!

Hey there! I had almost identical issues with my '05 Mitsubishi Outlander Diesel last year. The symptoms you're describing sound very familiar, my DPF was internally defective. When I took it to the garage, they found that the DPF's internal honeycomb structure was partially collapsed, which explained the black smoke and power issues. They had to remove the entire DPF unit to inspect it properly. Turned out the regeneration system had failed too, causing soot to build up way more than normal. The fix wasn't just a simple cleaning, they had to replace the DPF unit and reprogram the ECU to reset the regeneration cycles. It was quite a serious job that took them two full days to complete, but it solved all those symptoms you mentioned. The car runs like new now.

Hey, thanks so much for sharing your experience! That's really helpful to know about the DPF and regeneration system. I'm actually planning to get mine checked this week. Do you remember roughly how much you ended up paying for the whole job? Also, just curious, has everything been running smoothly since the repair, or have you noticed any other issues pop up?

Hey again! Great to hear you're getting it checked out. I can definitely tell you about the costs and how things have been running since then. The total bill came to 1550€ for fixing the internally defective DPF, which wasn't cheap, but totally worth it for how well the car's running now. I'm actually really happy to report that everything's been running perfectly smooth since the repair. The best part? That annoying DPF remaining mileage warning that used to pop up all the time is completely gone now. It's been about a year since the fix, and I haven't had a single DPF-related issue pop up. No more black smoke, no power loss, and the engine's running like a dream. It's such a relief when you get these things sorted properly, even if it does hurt the wallet a bit! Trust me, once you get it fixed, you'll notice the difference straight away. My Outlander feels like a different car now, in a good way! Let me know how your mechanic visit goes this week. Fingers crossed it's a straightforward fix for you too!

Thanks a lot for all the details! Just got back from the mechanic yesterday, and wow, you were spot on about everything. Had pretty much the same diagnosis, damaged DPF and messed up regeneration system. Cost me about 1600 €, which was a bit of a hit to the wallet, but honestly, it's like driving a different car now! The mechanic I found was great, super transparent about what needed fixing and why. They even showed me the old DPF unit, and yeah, it was properly busted. Took them about two and a half days to sort everything out, but the wait was worth it. No more black smoke, engine's quiet again, and that annoying power loss is gone. Really appreciate you sharing your experience, it helped me know what to expect and made me feel better about spending the money to get it done properly. Car's running like a dream now, and fingers crossed it stays that way! Thanks again for all your help!
