2010 Dacia Duster Exhibiting Performance Issues and Exhaust Problems, Possible Faulty Fuel Level Sensor

Hey! I've got a bit of a situation with my 2010 Dacia Duster that's just clocked up 92346 KM. I'm seeing black smoke when I accelerate, the check engine light is on and the engine cuts off out of nowhere. There's definitely a drop in power and the engine isn't stable - even jerks around when I accelerate. My car's eating up more fuel than usual, stalls when idling, and there's a strong smell from the exhaust. I had a rough time with my last mechanic and I'm thinking the issue might be a faulty fuel level sensor. Have any of you had something similar happen? Any recommendations for a reliable mechanic would be appreciated too. Thanks a ton!

Summary of the thread

A 2010 Dacia Duster is experiencing performance issues, including black smoke during acceleration, a check engine light, engine stalling, reduced power, increased fuel consumption, and a strong exhaust smell. The initial suspicion is a faulty fuel level sensor. However, a similar case with a Dacia Sandero revealed that the problem was due to a defective wiring harness, which, once repaired, resolved the issues. The recommendation is to consult a reliable mechanic to diagnose and fix the problem, potentially focusing on the wiring harness.

Hey there! This sounds a lot like an issue I had with my 2013 Dacia Sandero - similar symptoms with the unstable engine, the excessive fuel consumption, and the smoke and smell from the exhaust. I also thought it might be the fuel sensor, but after I took it to the garage, it turned out to be a defective wiring harness/plug. I know it sounds bad, and to be honest, it was a serious issue. It needed some pretty significant work done, but once it was fixed, my Sandero was back in smoother shape. Now, it's critical to find a good mechanic if you're dealing with this. It wasn't necessarily an easy process, but it was definitely worth it in the end. Just wanted to throw in my two cents – hope it helps! Be patient and don't rush to conclusions.

Hey, cheers for the input! Sounds like our Dacias had quite the twin troubles. The wiring harness issue you mentioned could indeed be a possibility since your symptoms match up with mine for the most part. So, you gotta help me out here can you recall roughly how much you splashed out for sorting the problem? And more importantly, has your Sandero been behaving well since the fix or did any new problems pop up? Thanks a ton!

Hey, no problem! The fee for fixing the defective wiring harness in my Sandero set me back 95€, but it was well worth the budget hit. Ever since the mechanic tackled that problem, my lovely Dacia has run like a dream - that fuel level sensor issue we thought it could be? Sorted. No more unusual engine cuts or jerky acceleration. Basically, all those irritating issues packed their bags and left. So, in short, it's been a smooth ride with no new troubles cropping up. Just remember to put your Duster in the hands of a trustworthy mechanic and you should be good to go. Hope this helps ease your mind a bit! Let me know if you have any more questions. Cheers!

Ah, you're a lifesaver! Really appreciate the insight. Sounds like our engine troubles were ditto. 95€ doesn't seem too bad if the old Duster can return to its good old days. I'm definitely keen to resolve the stalling and jerky acceleration issues. And a more stabilised fuel level is a promise too good to refuse! I'll be sure to find a trustworthy mechanic, I wouldn't want my car in the wrong hands again. Loads of thanks for the advice really put my mind at ease. I'll keep you posted on how it all goes down. Take it easy!
