Seeking Advice for 2022 Dacia Duster Diesel's Black Smoke Issue, Jerking Movement, and DPF Regeneration Failures

Hey! Thanks for reaching out. My trusty beast - the Dacia, hit the 62857 KM mark during my latest cruise around town. The recent service check was not too long ago, at 60000 KM. Apart from that, there hasn't been any major work done on it. Mostly, I use it for city drives during weekdays and occasionally for long-hauls over weekends. I've always been mindful to not let the fuel drop below a quarter tank, as I've read someplace this helps keeps the DPF in good shape. Though, by the looks of it, seems like something's slipped off the grid. That price tag you mentioned is indeed hefty! I guess I'll have to dig around for a good mechanic in my area now. Cheers!

Hey there again! Thanks for sharing the extra info. Your mileage and usage conditions do fit the circumstances where DPF issues crop up, especially considering the significant portion of city driving - where the engine doesn't always reach the temp needed for passive DPF regeneration. Now, before you start looking for that mechanic, maybe, just maybe, the DPF isn't clogged up beyond redemption. It could be the engine's running too rich because of a faulty sensor, leaky injector or EGR valve problems - common issues with these Dusters that can cause DPF blockage and other symptoms you're experiencing. Go for an exhaustive diagnostic first - might save some bucks if it's a sensor or injector issue. If the DPF does need to be replaced, check if there are any aftermarket options - could be cheaper than original parts. Ultimately though, you might want to schedule more frequent garage visits for forced DPF regenerations or invest in a DPF cleaning additive. In the meantime, if you can, avoid those short, low-speed drives. Try hitting the open road occasionally to get the engine hot enough for DPF self-cleaning. Hope this helps, and remember, it's your call at the end of the day! Best of luck!

Hey, thanks for the tips! That sums it up beautifully. I was completely clueless about the relationship between city driving and DPF blockage. Now, I think I have a better idea of what might be going wrong. I'll begin with checking those sensors and injectors you spoke about, before facing the huge elephant in the room - the DPF replacement. For now, I'll follow your advice about avoiding low-speed city drives and fill up some DPF additive too. Hopefully, this does the trick. Got a lot to think about on this, but your guidance has been invaluable. Will keep you posted on how it goes, fingers crossed! Thanks again!

Dacia Duster 1.5 Diesel 2017 (75,000 miles): The Car has run perfectly, but starting on cold mornings this week has been difficult. I got a new stop/start battery; it started reluctantly, but when the car was warm it started without a problem. While on a run today it began to make a peculiar noise, a kind of whooshing noise for about 5 minutes. There were no dash lights illuminated, the noise then stopped and the car continued to drive perfectly. It was then parked for about an hour, it started easily and drove away only to cut out a couple of minutes later and refuse to start. The AA man took the oil cap off, and the car then started but the engine wouldn't open up. There was white smoke coming from the oil filler hole, there were still no dash lights illuminated. The car had to be towed home. The AA man thought it could be a DPF blockage, however the car gets plenty of long runs on the motorway.

Based on your description, it could indeed be a DPF blockage, but the white smoke from the oil filler hole suggests there might be another issue. It could be a head gasket failure, which can cause coolant to leak into the engine and produce white smoke. However, this is just a guess and it's hard to say for sure without a proper inspection. I would recommend getting your car to a mechanic as soon as possible for a thorough check-up. Please keep us updated on the situation. Do you have any other questions or concerns?
