VAG 16488Mass air flow (MAF) sensor A circuit intermittent
16488 is the VW Group 5-digit number VCDS (and older VAG-COM versions) shows for P0104. P0104 means “Mass air flow (MAF) sensor A circuit intermittent”. It's a generic powertrain code (fuel and air metering), so it means the same on every make, including VW, Škoda, Audi, SEAT and Cupra.
