Seeking Advice on '09 Nissan Navara Diesel Performance Issues and Failed DPF Regeneration

Hey there! I've got some experience around this, not an expert but I've dabbled a bit. Had a very similar issue with my '07 Nissan Patrol. Turns out, it was indeed the Diesel Particulate Filter (DPF) which had become internally defective. I took it to my local workshop and after some diagnosis, they confirmed my suspicion. The DPF was replaced to resolve the issue. It's not a cheap fix, I shelled out around 1550 Euro for the whole thing. However, for a more specific diagnosis on your Navara, I'd need info like your mileage, your service history, and how often you've experienced DPF regeneration failure. With this, I'd be able to share more insights and tell you what else could be relevant to check. Peace!

Hey, thanks for the input! My Navara has racked up 182746 kilometers on the clock and the latest service was done not long ago. The DPF regeneration failure is a recent issue, becoming more frequent over the past few weeks. Again, any further insights you have would be awesome. Cheers!

Hey! Thanks for getting back with more specifics. Given the mileage and recent service, I’d definitely stick with the DPF being the main culprit here which aligns with your experiences. Especially, since the DPF problems have a tendency to become more frequent with time. You mentioned the issue with DPF regeneration started a few weeks ago. This could be related to a blockage in the filter, likely due to soot, leading to the failure in DPF regeneration. It's also not uncommon for some '09 Navaras to have these DPF issues given the mileage and age of the vehicle. I'd recommend not delaying any further and consider taking it to a decent diesel workshop—I prefer going local as they know the specific issues of the make and model in that area. Do keep in mind, it will likely cost you a solid amount for replacing the DPF like I mentioned earlier, around 1550 Euro or so. If the DPF is indeed the problem, replacing it should take care of the black smoke, power loss, unsteady engine and poor fuel economy. Let me know how it pans out. Best of luck, dude!

Hiya! That's some solid advice, I truly appreciate it. From the sounds of it, it is likely the DPF and I reckon getting it checked wouldn't hurt at this point. And yeah, local workshops seem to really know their stuff around these parts, so that’s a good shout. I'll brace myself for the cost - at least it'll hopefully sort all the other issues. Will defo keep you posted on how everything rolls. Thanks a ton for the help, cheers!
