Peugeot 301 Engine Overheating

I'm experiencing a worrying problem with my 2023 Peugeot 301 diesel. It's done about 60045 km. The engine is overheating, and the check engine light keeps popping on. I've also noticed coolant spilling under the car after driving, which I'm guessing is due to excessive pressure. I've checked the coolant level, and it seems fine when the engine is cold. I'm not really a car expert; could it be a software glitch or something?

Sounds familiar! I had something similar happen with my 301. Is it throwing any specific error codes, or just the check engine light? Could be a control unit communication fault. Worth checking the cable and plug connections to the components first.

Thanks! I don't have a code reader myself, so I'm just seeing the check engine light. When you say 'cable and plug connections', which control unit are you referring to specifically? Is it something I can easily check myself, or is it buried deep?

Yeah, without the code, it's tough to pinpoint. It ended up being a defective connection for me, triggering all sorts of weirdness. Honestly, unless you're comfortable poking around the engine bay, I'd advise getting it checked by a workshop. It'll save you a headache in the long run.

Thanks a lot for the advice! I took it to a local shop, and you were spot on – a defective cable connection to the control unit was the culprit. Repair cost me 95€ Appreciate the help!
