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!
