Overheating and indicator light on Peugeot 107: Possible causes and experiences with workshops

Hi guys, I need your advice. My 2007 Peugeot 107 (petrol engine, 35106 KM run) has a few problems. It overheats and the check engine light comes on. I suspect the coolant temperature sensor may be faulty. Have any of you ever had similar problems and how did you solve them? What was your experience with the garage? I'm really worried because the last visit to the mechanic went rather badly. I'm grateful for any tips!

Hello, my 2004 Peugeot 104 also had a similar problem, incidentally it was also a petrol engine. It was actually a serious problem and turned out to be a faulty engine control unit, not the coolant temperature sensor. The symptoms were similar: Check Engine light came on and the car tended to overheat. They first thought it was the coolant temperature sensor, but after a thorough check they found that the engine control unit was faulty. Of course, it was necessary to go to the garage for a repair to replace the faulty unit and get the car back to normal. It wasn't an easy fix, but it solved the problem and everything has been fine ever since. So from my experience, I would advise you to consider that too, and have the car checked by a professional. Hopefully that will solve your problem. Good luck!

Thanks for your advice! I wouldn't have guessed that it could be the engine control unit. Do you remember how expensive the whole thing became for you? And have you had any problems with the car since then, or is everything running smoothly now? I'm pretty annoyed about the whole thing and hope that I'll have peace of mind after this.

Hey, you're welcome! The engine control unit was indeed not cheap fun. It cost 1000 euros. Quite a lot of money, I tell you. But since then, everything has really been in the green. And you were right about the coolant temperature sensor. The mechanic has fixed it since my visit because it was faulty. Since then, I've had no more stress with the car - it purrs like a kitten now. Hopefully you'll get your speedster running again!

Hello, oh man, 1000 euros is a lot of money. But if it solves the problem and I can drive my car with peace of mind afterwards, it will probably be worth the price. And good to know that the coolant temperature sensor also plays a role. I really hope this fixes the problems. Thanks again for your advice and support. I'm off to the garage tomorrow morning and pray that all goes well. Keep your fingers crossed for me!
