Dacia Logan 2019 Electrical Issues: Asking for Similar Experiences and Garage Solutions

Hey! Had a similar problem with my 2016 Dacia Sandero, Petrol engine too, just around 35,000km. My beast started showing the same signs - erratic electrics, crazy lights, 'low battery' warning popping up now and then, and engine playing hard to get started. At first glance, it seemed like a unusual electrical issue, but the real troublemaker was the battery. Took it to my local garage. Initially they checked the alternator, but it turned out to be fine. The mechanic then did a test on the battery and voila - it was a defective battery. The battery had a weak cell and wouldn't hold charge, which caused the electrical chaos in the car. They basically replaced the battery and scrutinized the entire charging system just to make sure all was groovy. It was a bit of a serious issue in the sense it could have left me stranded in the middle of nowhere anytime! However, a sweet swap of the battery and a decent check of the circuit did the trick. Hope you get your Logan back up and kicking soon! Cheers!

Hey there, Reading your story feels like deja vu, my 2017 Dacia Logan gave me the same trouble not too long ago. Same situation: lights doing their own disco party, battery giving me the cold shoulder when trying to start the thing. Seemed like the car was possessed or something! Took it in to my mechanic, and it looks like you've hit the nail on the head with your guess - it turned out to be a dodgy battery. Mind if I ask how much that set you back? And have you had any other problems creep up since swapping the battery and checking the circuit? Cheers!

Hello, I must say, your story sounds pretty close to mine. After getting my battery replaced and the circuit checked, things have been pretty smooth with my Sandero. As for your question about cost, it did leave a dent in my wallet at 290 Euro. But in retrospect I think it was worth every cent. The relief of having the "Battery Defective" lights go out is something you can't really put a price on, especially considering how worried I was about the car packing up on me somewhere remote. Since the visit to the garage, the battery hasn't caused any more trouble, and that pesky "Interruption of terminal 30" got sorted as well when they were under the hood. No more unwanted disco shows from the lights or cold shoulders from the battery when I try to start it up! Hope this helps, and wishing your Logan a speedy recovery! Cheers!

Hey lads, Thanks for sharing your experiences! It's been really helpful. Seems like I've been barking up the right tree guessing it's a battery problem. I'll get the garage lads to swap out the battery for a fresh one and give the electric system a good one-two. Shelling out 290 Euro does smart a bit, but you're right, it's worth it for some peace of mind. Just hope my Logan won’t pull up any more surprises after this fix! At least no more worrying about being stranded in the boondocks when the electrics decide to go on the blink. Phew! Once again, thanks for your advice. Ta and take care!
