VAG 16537O2 sensor circuit slow response (bank 2 sensor 1)
16537 is the VW Group 5-digit number VCDS (and older VAG-COM versions) shows for P0153. P0153 means “O2 sensor circuit slow response (bank 2 sensor 1)”. 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.
