Check engine light and overheating in Peugeot 307: Possible causes and solutions

Hey, it was similar with my Peugeot 308 from 2006. The engine control light also came on and a warning light also flashed. I went to the mechanic and he said that the control unit for the parking heater was faulty. That was a serious matter. The technician had to replace the entire control unit and then readjust everything. So it seems that the fault lies between the control units. What I'm trying to say is that it could definitely be the control unit for the parking heater. It's best to take it to a specialist and have it checked. Greetings!

Hello, that sounds like exactly the problem I have. Nasty parking heater control unit fault! Do you remember how much it cost you? And have there been any other problems with your Peugeot since the repair or is everything running like clockwork? Thanks and best regards!

Moin, yes, that was a real blow to the account. It cost me €440 to fix the faulty parking heater control unit. But I have to say that since the mechanic got to work on my car, the problem with the message error between the control units has finally been solved. Annoying because of the cost, but it was necessary. Since then my Peugeot has been running like a kitten, so it was definitely worth it for me. Hope this helps you and have a good trip! Greetings!

Ah, that's a bit of a relief. My Peugeot is important to me and I don't want to consign it to the scrap heap because of minor faults. 440 is a lot of money, but if it helps and everything runs smoothly again afterwards, then it's definitely worth the investment. Thanks for your experience! I'll make an appointment with the mechanic tomorrow and hope that my car will soon be purring like a kitten again. Best wishes and have a good trip too!
