The interface wasn't refusing to connect; it was lodging an objection: it was weary of being a conduit for strangers who only wanted numbers and not the lives attached to them.

The VAG (Volkswagen Aktiengesellschaft) tacho interface is a standardized interface used in Volkswagen Group vehicles, including Audi, Seat, Skoda, and Volkswagen. The interface allows diagnostic tools to access and communicate with the vehicle's onboard computer, enabling technicians to diagnose and repair complex issues. The tacho interface is a critical component in modern vehicle diagnostics, and its malfunction can lead to significant disruptions in the diagnostic process.
