Windows-based Diagnostic tool for VW/Audi/Seat/Skoda for non-dongle interfaces.
The various computers in the car are called “Control Modules” or "Controllers".
There are dozens of different control modules that exist across the entire range of VW/Audi vehicles. No one car has all Modules! Newer cars have more, older cars have fewer. Because of this, you must select a Chassis Type that contains only those modules that are plausible for a given chassis.
