Volkswagen check engine light meaning

  • The gas cap is loose and needs to be tightened
  • The catalytic converter needs to be replaced
  • Worn spark plugs
  • An improperly working thermostat
  • The airflow sensor isn’t working correctly
  • A bad oxygen sensor

One question we get asked is “how long can I wait before I get my Volkswagen in for service?” When it comes to the check engine light, we recommend trying to tighten the gas cap and waiting a day or so to see if the light turns off by itself. A loose gas cap can allow oxygen to get into the gas tank and can trip up the oxygen sensor, which in turn illuminates the check engine light. If the light stays on after a few days or so, then it’s time to get your Volkswagen in for maintenance.
