Question

I am getting 4 codes on my 2000 Volkswagen Beatle 2.0L P0172, P0103, P0112, and P0422. Could this be the Mass Airflow Sensor?

Answer 1

Yes, it could be a faulty Mass Airflow (MAF) Sensor, but you should start by checking for intake and exhaust leaks. Especially before and after the MAF and Catalytic Converter
