1. Mass Air Flow (MAF) Sensor Failure

Symptoms of a Bad MAF Sensor

  • Check engine light with a MAF sensor code
  • Rough running engine or lack of power
  • Poorer fuel mileage

Causes of MAF Sensor Failure

The MAF sensor monitors the airflow entering the engine. The MAF sensor may fail in the 1998 to 2010 VW Beetle, and that can cause poor fuel mileage. A dirty engine air filter can cause dirt to clog the MAF sensor.

Changing the engine air filter is one way to prevent the MAF sensor from failing. If the MAF sensor has failed, replace it with a new one by removing the screws, disconnecting the connector, and swapping the old one with a new one.
