Seeking Advice on 2018 Nissan Cube Diesel Issues: Check Engine Light, Power Loss, Shaking, and Exhaust Smell

Hey there, so I've got some experience dealing with a similar issue. I'm no expert, just a regular guy, but I've been dealing with cars for a while now. I had the same head-scratcher with my 2016 Nissan Juke Diesel. EGR valve acting up can be a real pain. My solution was to get the old sucker checked out and sure enough, it was stuck. My mechanic replaced it with a new part and the whole thing set me back around 355 Euro. Though, it's best to get your ride fully checked. Let me ask you, have you noticed any unusual smoke? And what about your fuel consumption - any changes there? It helps to get the full picture. Hang in there, you'll get this sorted out!

Sup! Yeah, that sounds awfully like my situation. My cube has been chugging a bit more diesel than usual, and I've noticed some black smoke when revving. Mileage is pretty high, around 189,538 KM and the last service was early this year, but the mechanic didn't flag anything strange then. Thanks for sharing your experience with your Juke. Guess I'll bring my big boy to the garage and get all the bits and bobs checked out. Especially the EGR valve! Fingers crossed it won't be more than a few hundred Euro! Cheers!

Hey, good to hear back from you! Man, that sounds pretty much like EGR valve issue mixed with some turbo failure. The black smoke you mentioned points toward turbo. That happened with my Juke as well at around 170K KM. I guess it's something with Nissan Diesel Engines at high mileage! On top of my EGR valve swap, I ended up doing some work on the turbocharger too. That bumped the cost a bit but trust me, it's worth it in the long run. Your engine will thank you, and so will your wallet when you see your fuel consumption drop back to normal. Also remember, a 'check engine' alert can be anything, right? Better safe than sorry, my man. Bring your cube in for a full engine diagnostic instead of just the EGR valve. This will save you from future headaches! Expect to shell out a chunk of change, but hey, it's an investment into keeping the machine rolling! Best of luck, and keep us updated on what they find! Cheers!

Hey, I appreciate your detailed response! Yeah, honestly didn’t think about potential turbo failure. That's definitely not something to take lightly. I'll follow your suggestion and get a full engine diagnostic, with a focus on EGR valve and turbocharger. Black smoke and increased fuel consumption do point towards those! It might dent the wallet a bit, but I'm with you, man, gotta keep the machine rolling smooth. Better invest now than regret later, right? Can't properly express how helpful your advice has been! I'll definitely keep you and everyone else here posted on what the mechanic says. Toodles for now! Let's hope for the best. Cheers!
