Peugeot 308 Stop Start Not Working

Here, we explain the most common reasons for the Peugeot 308 stop start not working. The Peugeot 308 stop and start system puts the engine temporarily into standby, helping to reduce fuel usage and pollution. When the car enters stop mode, the green ‘ECO’ warning light illuminates on the dashboard instrument display. If stop mode is not available, the ECO warning light flashes for a few seconds then goes off. (See Peugeot 308 dashboard warning lights for the various other symbols.)

Specific conditions must be met for the Peugeot 308 stop mode to be initiated. If you’re frequently having issues with your Peugeot 308 stop start not working, it’s likely to be one or more of the following conditions:

• Stopping on a slope, either up or down, usually of a gradient of 9 percent or more.
• The driver’s door is open.
• The drivers’s seat belt is not fastened.
• The vehicle has not exceeded 6 mph (10 km/h) since the last manual engine start by the driver.
• The engine coolant temperature is either too hot or too cold. This is usually in the range of below 10°C or above 100°C.
• The electric parking brake is applied or is being applied.
• Outside air ambient temperature is too hot or too cold. This is usually in the range of below -5°C or above 35°C.
• Temperature of diesel is too hot. Usually in the range of 60°C or above.
• The engine is required to maintain a comfortable temperature in the passenger compartment and the current temperature is too dissimilar to that set on the A/C system.
• Demisting is active.
• Number of restarts per minute has been exceeded. This is usually 6 or more.
• Automatic gearbox oil temperature is too high or too low. This is usually within the range of below -5°C or above 118°C.
• Battery charge is too low. This is usually when there’s a state of charge of 75 percent of less. Low battery charge is the most common reason for the Peugeot 308 stop start not working.
• Internal temperature of the battery is too cold or too hot. This is usually from below -5°C or above 60°C.
• Braking assistance (vacuum reserve pressure) is insufficient for braking assistance.
