Hey, thanks for your answer! I've only driven 38985 KM with my Peugeot 408 and the last service was also very recent, so there aren't really any problems. That sounds possible with the control unit, I'll have it checked out at my garage. Hopefully it won't be as expensive as yours, but it's definitely better than the constant overheating. Thanks again for the tip!

Hello again! Nice to hear that you want to keep at it. With the mileage, it would actually be premature for such problems. The coolant level also sounds like something you should pay attention to. Maybe you have a small leak somewhere, which is causing the coolant level to drop and lead to overheating. It's quite possible that this has something to do with your problem. Check it out if you have the opportunity. Your garage may also be able to help you find the fault. But be careful not to drive too much when the warning light is on and the engine is overheating. This can really damage the engine! Hopefully I've been able to help and good luck sorting it!

Wow, thanks for your far-reaching considerations! I haven't actually considered a leak yet, I'll certainly be motivated to check it out. Fortunately, my garage is very reliable and I trust that they will find the fault quickly. You're absolutely right, I shouldn't keep driving while the problem persists - it could just cause more damage. With so many things to keep an eye on, I'm really grateful for your advice! Your post helped me a lot and I'm more reassured now. Thank you again! I'll be in touch with some news. Until then, take care!

Hi, I once had a very similar problem with my 2009 Peugeot 406 diesel. I would say I have limited experience with cars, so I'm not an expert, but I know a thing or two. At my garage, they replaced the control unit because there were sporadic faulty communications between the control units. It cost me around 955 euros. I would suggest you have it checked. It seems to happen more often with Peugeots in our age range. Can you give us more information about your vehicle? Mileage, service history, etc. could help to identify the problem more precisely.
