Seeking Solutions for Hyundai i30 Diesel Issues: Black Smoke, Engine Light On, Reduced Power, and DPF Regeneration Problems

Hey there, sounds like some pesky trouble you're experiencing. Your situation is a bit similar to what I dealt with on my 2015 Hyundai i40 Diesel a while back. Just to fill you in on my car knowledge, I have some experience, mostly from dealing with issues like these over the years. Anyway, I ended up taking my ride to the local garage where they diagnosed it as a heavily loaded DPF. Cost me a cool 1325 Euro to sort it out. They had to do a force regeneration and cleaned the DPF using a special solvent. They also replaced the exhaust pressure sensor to get everything back to normal. So, you might want to check with your mechanic about this. A couple of questions I have for you: Did you recently change the type of fuel or try any additives? And what's your car's mileage? I ask because these factors might affect the DPF and its functionality. Let me know so I can help you out a bit more. Cheers!

Hey, thank you for your input! Now that you've mentioned it, force regeneration and sensor replacement could be a viable solution, I'll sure talk about this with my mechanic. As for your questions, the fuel type and additives are the same ones I've been using since I bought this ol' beauty. As for the mileage, it's at 51207 KM at the moment. Cheers for your help!

Hey again! Based on your mileage, it does sound like your DPF might be heavily loaded. Especially in city driving, short trips don't give the DPF the time & heat it needs to regenerate properly, hence it gets loaded over time. Given your car's mileage and the issues you're experiencing, a blocked DPF matches the symptoms. Sounds like your mechanic should definitely look into force regeneration, sensor replacement, and possibly cleaning your DPF. Don't be surprised if it costs a bit, as the treatment I mentioned earlier for my i40 wasn't exactly cheap! Another point I suggest you to check is the injector valves and turbocharger, as these are also notorious for causing black smoke & power loss. Your mechanic should be able to give them a good look over when you bring it in. Hope this helps. If you have more questions or updates, feel free to share! Cheers!

Hey there again, you're a wealth of great advice! Makes a lot of sense about the city driving and short trips affecting the DPF - that's mostly what I do. Seems like I've quite possibly neglected the needs of my DPF. I'll brace myself for the cost you mentioned while sorting this all out. I'll make sure my mechanic gives the injector valves and turbocharger a once-over too. Cheers for pointing that out, much appreciated! You've given me plenty to go on. I'll pop back with any updates or more questions after my visit to the garage. Thanks a heap for all the help!
