Overheating problems and check engine light on 2017 Renault Talisman - Possible causes and solutions

Hey, I had a similar problem with my 2015 Renault Megane. I would describe myself as someone with little experience in cars, but I can say that the coolant pump can sometimes go crazy. My garage found that the cable on the pump/control unit was faulty. It cost me 95 euros to fix it. But without more details about your car, like the exact model information and current mileage, I can't say much more. Hope this helps a little!

Hey, thanks for your quick reply. My Renault Talisman only has 22777 km on the clock and has not yet been checked in the workshop. The cable could be the problem, as you said. I think I'll have a look at it or, if I'm unsure, contact my mechanic. Fortunately, 95 euros is not that much. Thanks again!

No problem, I'm glad if I could help! With such a low mileage, it could actually be the cable. However, there's never 100% certainty, especially in machines as complex as cars. If you don't dare to try it yourself, definitely have it checked by a mechanic or in a workshop. Don't end up breaking more than you repair. And 95 euros is of course still reasonable, but who knows. If it's something else, it could of course be more expensive. I'll keep my fingers crossed that it's just as easy (and cheap) for you to fix as it was for me. Good luck!

Yes, you're right. It's better to play it safe and call in a professional. Thanks for the advice and especially for keeping your fingers crossed! I hope I'm as lucky as you and it's nothing serious. Let's see what the mechanic says. Thanks again for your help! Bye!
