Problems with the fan and solar sensor of the Peugeot 4007 Diesel, model year 2007: experiences and solutions

Hi guys, I have a strange problem with my 2007 Peugeot 4007 Diesel, the fan is not working properly, the cooling/heating is inadequate and a warning light is showing in the speedometer. I think the solar sensor might be faulty, have you had similar experiences? How did you solve the problem in the workshop and what was your experience? I am grateful for any tips and advice.

Hello, I have had a similar problem with my 2009 Peugeot 407 Diesel. I have average experience with cars. The problem I had was actually with the wiring harness, which was defective. I had it repaired at my regular garage. The damage cost me about 155 euros. It was pretty annoying, but everything worked great again afterwards. Can you give us more information about the vehicle? Have you noticed if any other functions are faulty or if there have been any other problems recently? That might help diagnose your problem better. Hope this helps you!

Hey, thanks for your reply. My car has already run 115122 km, but apart from the fan problem, nothing else seems to be broken. Nothing special was mentioned at the last service. A few skeletons in the cupboard, yes, but that's all I'll reveal ;) I'll keep your advice about the wiring harness in mind and maybe visit another garage. Thanks again!

No problem, always happy to help! A vehicle with 115122 km is no longer very young, but in principle the Peugeot should still run without any problems. If there are no other known problems, the wiring harness problem sounds really plausible. But I would also recommend that you check the solar sensor, which may also be damaged. Even if this is rather rare. Oh yes, and about the garage - try somewhere else. Sometimes it really makes sense to get a second opinion. They might find the cause more quickly or even be able to fix it more cheaply. And don't worry about the 'skeletons', we all have them hidden somewhere ;) Good luck, hopefully everything will be resolved quickly!

Great, many thanks for the additional tips! I will also have the solar sensor looked at. And yes, you're right, a second opinion is always good, I think I'll try another workshop. Thanks for the encouraging words about the 'skeletons' - as they say, "nobody's perfect" ;) Thanks again for the help and good advice! Your experience has really helped me. Hopefully nothing will stand in the way of my little 'box' again soon. All the best!
