Seeking Advice on '14 Dacia Sandero Petrol Overheating and Check Engine Light Issues

Hey there! I had a similar thing happen to my '12 Dacia Logan Diesel not too long ago (I've got some experience, but not much in the grand scheme of things). Before you dive right into the coolant temp sensor, double-check the cable connections or plugs to see if they're faulty. For me, my mechanic found a defective cable connection that was causing the symptoms you're describing. The total damage? Nothing more than 95€. Not too bad in the end. Are there any modifications to your Sandero? Or have you recently serviced it or replaced any parts? Knowing this could help me give you more tailored advice. Hope this helps!

Hey, thanks for the quick reply! No major modifications done on my Sandero really, it's all pretty much stock. I got her serviced just recently at 33717 KM, with no new parts replaced surprisingly. I will look into the cable connections as well, didn't think of that. Love how we car people get to save some cash by DIY-ing! Cheers!

You're welcome! Keeping it stock is always a good idea, less chance of unexpected issues cropping up. Great to hear that your Sandero got a recent service, it definitely rules out a host of potential issues. The mileage you mentioned usually doesn't bring up any major hold-ups either. So yeah, the cable connections should be your first pit stop, just to make sure everything's tight and right. Another thing worth mentioning - a malfunctioning thermostat or a clogged radiator could also cause overheating and the check engine light to come on. So, it could be worth checking those out too if the cables look fine. And indeed, nothing beats the satisfaction you get from a successful DIY job! Looking forward to hearing about your progress. Keep us in the loop! Best of luck!

Cheers for the advice! I hadn't thought about a dodgy thermostat or a clogged radiator as the potential culprits. I'll be sure to check those out too when I'm having a look at the cables. I'll let you lot know how I get on with it! Sure do love the thrill of being my own mechanic, haha. 'Til next time and wish me luck!
