Engine management light on: what should you do?

20-12-2023

If the engine management light is illuminated on your vehicle’s dashboard, this may indicate a possible fault in the engine management system. Here are the steps you can consider when the engine management light comes on:

  1. Stop safely: Reduce speed and stop the vehicle in a safe place away from traffic.
  2. Check other warning lights: See whether any other warning lights are illuminated on the dashboard, as these may help identify the problem.
  3. Check the fuel cap: A loose or poorly sealed fuel cap can sometimes trigger the engine management light. Check that the fuel cap is properly tightened.
  4. Check the battery: A weak or faulty battery can also cause faults. Check the battery terminals for corrosion and make sure the battery is properly connected.
  5. Check fluid levels: Check the oil level, coolant and other fluid levels. Insufficient oil or coolant can cause problems.
  6. Restart the engine: Switch off the engine and wait a few minutes before restarting it. Sometimes the engine management system may have a temporary fault that clears after restarting.
  7. Have the car diagnosed: If the engine management light remains on, it is advisable to have the vehicle read by a professional mechanic using a diagnostic tool. This allows fault codes to be read, indicating the specific problem.
  8. Schedule maintenance: If the cause of the problem is not clear, schedule a service appointment with an authorised dealer or garage. A qualified mechanic can carry out the necessary inspections and repairs.

Please note: the engine management light does not always immediately indicate how serious the problem is. However, it is important not to ignore it, because some issues can lead to further damage to the engine or other vehicle systems if left unresolved.

If you are not sure what to do, it is always safer to seek professional help. It is better to address problems early to prevent more serious damage.
