Service Warning Light
The Peugeot 308 service warning light comes on temporarily due to a minor fault. The service light stays on constantly due to a serious fault where there is no dedicated fault light. A warning message may also be displayed on the dashboard. Minor faults include:

  • The engine oil level is low
  • The screen wash level is low
  • The remote control key battery requires replacement
  • The tyre pressures are low
  • The electric parking brake has a minor fault
  • Emergency Collision Braking System fault
  • The soot saturation level is high for the diesel particulate filter (DPF) / particle emissions filter (PEF) on diesel vehicles. To clean or regenerate the filter, continue driving at a speed of 40 mph until the warning light goes out.
