What can your car do?

What is coding, and what is it good for?

The control units in modern VAG-group cars (Audi, Skoda, Volkswagen, Seat, Cupra) contain many functions that the factory leaves switched off for a given trim level or market. Some of them can be enabled or changed with a diagnostic tool such as VCDS, OBDeleven or ODIS. This is called coding, or adaptation.

If a function also needs new hardware (a different lamp, display or sensor), it is a retrofit. We mark these as their own category.

We collect the options car by car. Each entry lists the control unit involved, the tool you need, the difficulty level and the steps.
