Dacia Logan Overheating Issue and Check Engine Light Dilemma

Hey there, I totally get you had a similar issue with my own ride, a 2009 Dacia Sandero. Turns out, it was a damaged wiring harness causing all the chaos. When I brought it to my garage last time, the mechanic had to perform quite some work to address the issue. Had to check all the wires connecting to the engine, found some burnt ones, and basically rewired things back into place. Honestly, it wasn't a minor problem at all. That damaged wiring harness could have potentially damaged other components as well. But once it was all sorted, everything fell right back into place, no more overheating or troublesome check engine light. So do keep that in mind too, just in case. Cheers!

Oi I've got a 2008 Dacia Logan and faced a similar nightmare just a few months back. It turned out to be a faulty thermostat for me. Got it replaced, and it's been all smooth sailing since then. No more nagging lights on the dashboard or anything. Just curious though, do you remember roughly how much dough you had to drop for that fix? And have you noticed any other gremlins creeping up since the repair? Would be good to know, being fellow Dacia owners and all. Cheers!

Hey! Spot on, your insight about the thermostat was bang on the money! Thought I'd update you since my last visit to the mechanic. The dude figured it was indeed the coolant thermostat that was causing the upset. It's been replaced and I'm not seeing any more of those vexing overheat warnings or that darn check engine light. As for the cost query, the whole ordeal with the wiring harness initially cost me about 170€. It was a bit of a sting in the pocket but worthwhile in the end. No nasty surprises or little monsters lurking around since then. Nada, zilch, nothing! So far, my Dacia's been humming like a lullaby. Thank heavens! Stay safe on the road. Cheers!

Thank you, guys! I made a trip to the mechanic, and it indeed turned out to be the coolant thermostat playing havoc. I had it replaced and no more niggling lights or overheating problems since then. It cost me a decent 155 €, not as hefty as I feared, though. Glad to hear your encounters with similar issues weren't too dreadful. Gives me hope for my Dacia! Hope it keeps purring for a while now. Thanks again and safe driving everyone. Cheers!
