VAG 16885Vehicle speed sensor A range/performance
16885 is the VW Group 5-digit number VCDS (and older VAG-COM versions) shows for P0501. P0501 means “Vehicle speed sensor A range/performance”. It's a generic powertrain code (vehicle speed, idle control and auxiliary inputs), so it means the same on every make, including VW, Škoda, Audi, SEAT and Cupra.

Typical causes are a starting point, not a diagnosis of your car.
What a shop would usually check first
The sensor and its wiring; implausible signals often come from a connector or a damaged sensor.
