mass airflow sensor

  1. Maf/ air intake system leak

    Questions, Issues or Problems with the New Beetle
    I have a 2010 with the 2.5 5cyl and I keep throwing the code for "mass air flow sensor out of range", and sometimes codes for "air intake system leak" and "secondary air upward stream detected" I just replaced the maf sensor and it's still pulling the code, and I'm clueless. If anyone has any...
  2. Mass Airflow Sensor - Clean or Replace?

    1.8 Liter Turbo
    I just took my 2001 Beetle to the dealership to diagnose my check engine light. (there were too many codes to figure it out myself) Anyway, they told me to replace the MAS. I'm trying to figure out if there's a quick/easy way to tell if the MAS is gone or just really dirty. Any advice?
