VAG 16400Crankshaft/camshaft position correlation (bank 1 sensor A)
16400 is the VW Group 5-digit number VCDS (and older VAG-COM versions) shows for P0016. P0016 means “Crankshaft/camshaft position correlation (bank 1 sensor A)”. It's a generic powertrain code (fuel, air metering and emission controls), so it means the same on every make, including VW, Škoda, Audi, SEAT and Cupra.
