Honda WR-V Diesel: Black Smoke and DPF Troubles

Jerking on acceleration

DPF regeneration failure

Check engine light on

Black smoke from exhaust on acceleration

|

Strong exhaust smell

Hey everyone. My 2021 Honda WRV diesel is acting up with multiple issues. Getting black smoke under acceleration, engine warning light, failed DPF regen, jerky acceleration, and strong exhaust fumes. Pretty sure it's related to a clogged DPF. Has anyone dealt with similar symptoms? Would love to hear about your repair experience and what the actual problem turned out to be. How did your mechanic fix it? Thanks in advance.

Hey there! I've got some experience with cars and had a really similar issue with my 2019 Honda BR-V diesel last year. Those symptoms sound exactly like what I dealt with. My BR-V showed the same signs, black smoke, warning lights, rough acceleration, the whole package. Took it to my regular workshop and they diagnosed a faulty DPF that needed replacement. It wasn't cheap (cost me about 1550 Euro), but it fixed all those issues completely. The mechanic explained the DPF was internally damaged beyond repair, not just clogged. Before we dig deeper, what's your mileage and maintenance history? Also, have you noticed any specific driving conditions when these symptoms get worse? This info would help me understand if you're facing the exact same problem I had. Pro tip: If it is the DPF, don't wait too long to get it fixed. I learned that the hard way when I tried to push through it for a few weeks!

Thanks for sharing your experience! I've got 29194 KM on the clock and just had my service done recently. The symptoms definitely match what you described with your BR-V. I'm noticing the black smoke and jerky acceleration especially during highway runs, and it's pretty concerning. Interesting that you mention the complete DPF replacement. I was hoping a cleaning might do the trick, but from what you're saying, I might need to brace for a bigger repair. Did you notice any improvement in performance after the replacement? I'm a bit worried about the cost, but I guess it's better than risking more damage to the engine. Let me know if you've got any other tips from your experience, really appreciate the help!

Hey again! Thanks for those details about your WR-V. Wow, those symptoms at just 29K km do sound concerning, my BR-V had similar issues but at around 45K km. After my DPF replacement, the difference was like night and day! The engine ran so much smoother, no more black smoke, and that annoying jerking during acceleration completely disappeared. My fuel economy even improved a bit, which was a nice bonus. Quick tip from my experience, while you're getting it checked out, have them look at the EGR valve too. In my case, it turned out the EGR was partially clogged as well, contributing to the problems. Getting both sorted at once saved me another potential headache down the road. The cost might seem steep now, but trust me, it's worth fixing properly. I tried limping along for a while, doing short-term fixes, but that just made things worse. Also, check if your warranty might cover any of this, I wish I had done that earlier! Keep me posted on what you find out. Happy to share more specific details about what helped me if you need them!

Thanks so much for all the detailed advice! It's really helpful to hear from someone who's been through the same thing. You've convinced me to get it checked out properly rather than trying any quick fixes. The tip about checking the EGR valve is especially useful, I'll definitely mention that to my mechanic. Funny enough, right after reading your message, I called my dealer to check about the warranty coverage. Keeping my fingers crossed on that one! It's reassuring to hear how much better your car ran after the repairs. The improved fuel economy sounds like a nice silver lining too. I'll definitely update you once I get it looked at. Really appreciate you taking the time to share your experience, it's made me feel a lot more confident about handling this whole situation!
