Hey, I had a similar problem with my 2013 Renault Laguna Diesel, where the cable to the pump/control unit was faulty and the symptoms were similar to yours. The check engine light was on and my car was a little warm. The repair required a mechanic to open the pump, find the faulty cable and replace it. It was pretty critical because a faulty cable is a fire risk. So my advice would be to get it checked immediately. Hope this helps you. Good luck!

Hey, thanks for your help! Your experience sounds pretty similar to mine. Could you maybe remember the price you paid for the repair? And did anything else come up after replacing the cable or has everything been running smoothly for you since then? Regards!

Hey, you're welcome! Sure, I still remember the price! It cost me €220 to repair the cable on the pump/control unit. Once the mechanic had taken care of it, everything ran like clockwork again. It was particularly reassuring that the coolant pump was working perfectly again - no more overheating, and the engine control light also went out. I haven't had any further problems since then. So don't worry, as soon as it's repaired, everything should be running fine again! Best regards!

Hey, thanks for the info! That's a great relief to hear. I'll take your advice and make an appointment at the garage straight away. It's just not worth the risk. The price also seems fair to me. Hopefully everything will run as smoothly as it did for you after the repair. Thank you very much and take care! Bye!
