Accord Diesel: Black Smoke & Stalling, Injection Issues?

Hey there! I can relate, had a similar headache with my 2007 Honda Civic Diesel last year. I've got some experience working on cars, but nothing too advanced. The symptoms you're describing sound exactly like what I dealt with. After getting error codes from the computer, it turned out to be an issue after a fuel filter change. The system just needed to be properly bled and reprogrammed. My regular workshop sorted it out in about an hour, cost me 45 Euro for the diagnostic and reset. Running smooth as butter since then! Before I share more specific details though, could you tell me if you've had any recent work done on the fuel system? Also, what's your current mileage? This could help pinpoint if we're dealing with the same problem. Quick tip: while you're at it, ask your mechanic to check the fuel pressure sensor too. That can sometimes trigger similar symptoms.

Thanks for sharing your experience! My Accord's at 216875 KM and had its last major service about 3 months ago. Your Civic story sounds pretty similar to what I'm experiencing. Interesting about the fuel filter and bleeding, actually, now that you mention it, they did replace the fuel filter during that service. Maybe they didn't bleed the system properly? That's really helpful about the pressure sensor too, I'll definitely get that checked. Did your mechanic mention any other potential trouble spots while fixing yours? 45 Euro sounds way better than the repair quotes I've been getting!

Hey again! Yeah, that definitely sounds like the same issue I had with my Civic! When you mentioned the recent fuel filter change, that pretty much confirms my suspicions. When they worked on my car, the mechanic actually explained that improper bleeding after a filter change is pretty common. Even experienced techs sometimes rush through it. My Civic had almost the same mileage as your Accord when this happened, around 220,000 km. Something else my mechanic pointed out while fixing mine, there's a specific sequence for bleeding these Honda diesel systems. If it's not followed exactly, you get all those symptoms you're describing. The black smoke and power loss are classic signs of air in the system. And get this, initially, another shop quoted me something ridiculous like 500 Euro because they thought it was a faulty injector! That's why I always recommend getting that system bleed and reset done first before replacing any expensive parts. Quick tip from my experience, if you decide to get it checked, make sure they do a full pressure test after bleeding the system. My mechanic showed me how the readings should look on the diagnostic tool. It's worth the extra time to get it done right. Let me know how it goes! Based on what you're describing, I'd bet good money it's the same problem I had.

Thanks a lot for all that detailed info! You've really given me a clearer picture of what to look into. I'll definitely take it back to my mechanic and specifically ask about the bleeding procedure, can't believe such a simple thing could cause all these problems! I'm feeling much more confident now about pushing back on expensive repairs before checking this first. I'll make sure they do that pressure test you mentioned too. Honestly, it's such a relief to hear someone had the exact same issue and got it sorted without spending a fortune. Will definitely update once I get it checked out, hoping for that same 45 euro fix rather than the scary quotes I've been getting! Really appreciate you taking the time to explain everything in detail. This could save me a lot of headaches and money. Thanks again for all the help!
