Peugeot 208 Start Stop Problem
Summary of the thread
A 2012 Peugeot 208 diesel experienced issues with its start-stop system, including the engine shutting off and a warning light on the dashboard. The problem was suspected to be related to a defective or discharged battery, as the start-stop system relies heavily on a healthy battery. After testing, it was confirmed that the battery was heavily discharged and needed replacement. Once replaced, the start-stop system functioned correctly again.

Thanks for your reply. The battery seems fine, the car starts without problems. Could it be something else besides the battery? Any ideas?

While other issues can affect the start-stop, based on your symptoms, a failing battery is most probable, especially if it's the original one. I would recommend having the battery professionally tested. A discharged or defective battery can cause the start-stop to malfunction and also shows the described symptoms. Better have someone check the error codes, too.

Thank you. I took your advice and had the battery checked. It was indeed heavily discharged and needed replacing. New battery cost me 290€. The start-stop system is now working perfectly again.

I also drive a Peugeot 208 and experienced similar issues with the start-stop system. The engine shutting off unexpectedly is concerning. Is the battery showing any signs of weakness? Start-stop relies heavily on a healthy battery to function correctly; it needs enough charge to restart the engine quickly and reliably, otherwise the eco mode and starter motor are disabled for safety reasons.
