I've just replaced the battery on my 2015 208, as it decided to die on me. (Ungrateful little swine).🤬🤬🤬

Now comes the kick in the teeth. The engine management light has come on and the system is telling me that it needs repairing.

Am I correct in thinking that I need to get the car into Arbury to have the systems reset? 😵

Any advice / help much appreciated.

Hello, I work in automotive electronics and have seen this a couple of times. Not sure if Peugeot has voltage monitoring but if a battery gets low the voltages to the dash, ECU, sensors are all reduced. Sometimes even causes the car to enter limp home mode. As cars get smarter and more complex a small loss of voltage can be all the difference.

Fastest way to a definite answer is get the codes read. Determine the area to look at and heck could be a simple clear and away you go. I got one from Amazon cheap and never looked back. Worth every penny.

First thing I would be doing is going back. Check both battery terminals are tight, correctly seated and making good contact.

Check the new battery voltage is 12-13v and is indeed the correct battery for your car. Seen new dead batteries (not common yet not unheard of) and sometimes the wrong battery can be offered. Worth a check

You could try and remove the battery for 15 minutes to let the ECU reset. I assume no radio codes would be lost in your vehicle??? Then reconnect battery and see what happens.

Sorted. Wasn't the 🤬 battery at fault. Main engine fan control unit was buggered.

Damned thing.
