Weak battery and flickering lights on Peugeot Partner 2008: Possible fault with the temperature sensor?
(Translated from German)
Summary of the thread
A 2008 Peugeot Partner is experiencing a weak battery and flickering lights, raising concerns about a potential fault with the vehicle battery temperature sensor. A similar issue in a 2005 Peugeot 308 was resolved by replacing the engine control unit, which had caused communication problems with the battery. It is suggested to discuss this possibility with a mechanic, as replacing the engine control unit resolved the issue in the other vehicle, leading to smooth operation thereafter.

Hey, thanks for the quick reply! Sounds exactly like my problem with the Peugeot. I hadn't even considered the engine control unit. Do you remember how much it cost you to have it replaced? And have there been any other problems since then? I'd be really interested to be prepared before I go to the mechanic. Thanks in advance!

Hey, no problem, always happy to help! Well, replacing the engine control unit cost me €1000 at the time. Of course, it wasn't a small price to pay, but after that the problem was solved. And since the visit to the mechanic, there have been no more faults with the vehicle battery temperature sensor. The car has been running like clockwork ever since! So it's money well spent, if you ask me. Hopefully yours will get back on track soon, fingers crossed!

Hey, thanks for the helpful information! 1000 € is expensive, but if it means my Peugeot runs like before, it's worth it. Great to hear that you haven't had any further problems since the repair. That gives me a bit more confidence the next time I go to the garage. Many thanks for the tips and for keeping your fingers crossed! Bye and have a good trip!

Hey, I know exactly what you mean. I had a similar problem with my 2005 Peugeot 308 and the diagnosis was a faulty engine control unit. This often shows symptoms such as flickering lights and starting difficulties because it can no longer communicate properly with the battery, similar to yours. We were quite surprised because the car was otherwise running perfectly. But of course, the engine control unit is incredibly important for the overall operation of the vehicle, which is why my mechanic took it quite seriously. He replaced it and since then everything has been running smoothly again. So maybe that's the cause in your case too. You can talk to your mechanic about it and have it checked. Hope that helps you!
