Flickering lights and weak battery in the Peugeot 3008: experiences and mechanic tips

Hey, I really understand your problem. I was in a similar situation last year with my Peugeot 308 (2019 model year). The symptoms were pretty similar to yours, flickering lights and general problems starting the car which pointed to a battery problem. My car mechanic diagnosed a faulty battery sensor microprocessor. It was a tricky situation as the sensor was affecting the connection to other systems in the car. Normally, the processor is responsible for extending the life of the battery and preventing it from being over-discharged. Therefore, it was important to get it repaired as soon as possible. He had to replace the sensor and it took a little time as he had to make sure the new part was working correctly and the problem was completely fixed. With the replacement part, everything was back to normal and my car ran like clockwork. Don't worry, it's not an "end of the world" problem, just something you should get fixed as soon as possible. Hope this helps you.

Hey, thanks for the detailed description. That does sound like the problem with my 3008. Do you remember how much the repair cost you in total? And has the problem recurred since then or were there perhaps other subsequent faults that were triggered by it?

Hey, you're welcome! Yes, the problem with the battery sensor microprocessor was completely solved after I went to the mechanic. Since the repair, everything has been running perfectly, the lights no longer flicker and the battery delivers full power when starting. Don't worry, nothing else has broken since then. The repair and replacement of the sensor cost me €315. A bit expensive perhaps, but it was worth it, the car is now running smoothly again. The main thing is that the fault on the vehicle battery sensor is gone!

Oh, great! So it sounds like it was money well spent. I'm glad to hear that you haven't had any further problems since then and that your car has worked perfectly again after the repair. I suppose I'd better take care of this problem right away. So off to the mechanic! Thanks for the help and advice, that really helped me out!
