2014 Nissan Note: Experiencing Black Smoke, Unexpected Shutdowns, and Power Issues - Suspected Faulty Fuel Volume Regulator

Hey, sounds like you're having a real headache. Your suspicions about a faulty fuel volume regulator might be right, but your symptoms remind me of what happened to my 2011 Nissan Qashqai. I had similar issues, especially the jerking during acceleration, the engine shutting off, and that atrocious exhaust smell. It turned out to be a defective high-pressure pump. The mechanic did some diagnostic tests and checked the fuel pressure and volume. He found out that the high-pressure pump was not functioning as per, and it was causing improper fuel distribution. This problem was quite serious as it was causing potential damage to the engine and increasing fuel consumption. He ended up replacing the pump. After the replacement, the car was running way smoother, the jerking stopped, no more black exhaust smoke, and the fuel consumption returned to normal, so in my case, the experience was pretty good. Remember, every vehicle might react differently to similar problems and it's crucial to have a reliable mechanic check it out. So, get your Note checked out ASAP, it might just be the same issue I had. Good luck!

Hey there! Sounds like you've been through the wringer with your Qashqai. It's interesting that your symptoms are quite similar to what I'm experiencing with my Note. The defective high-pressure pump angle hadn't crossed my mind, but it does make sense given what's been happening. So you ended up replacing your pump, right? Just out of curiosity, do you recall how much you had to fork over for that repair job? And have you experienced any other problems since then or is your ride smoother now? Just trying to get a sense of what I might be dealing with here. Cheers for your help!

Hey there! Absolutely, my car's a lot smoother since that repair job, like a brand-new set of wheels. The faulty fuel volume regulator was fixed - and, let me tell you, what a difference! Now, as for that jab to my wallet when I got the high-pressure pump replaced... It did set me back a bit - 1510€ to be exact. But consider this: it probably saved the engine from a major meltdown further down the road. So, I'd say it was money well spent. Ever since then, everything's been hunky-dory, and I've had no repeat performances of the same issues. Giving the car to the mechanic did a world of good. Make sure you get someone reliable to have a look at your Nissan Note. Cheers, and keep us posted!
