Guía de codificación para Activar enganche de remolque tras reequipamiento en Audi A6 C7 (4G). Compatible con VCDS / VAG-COM · OBDeleven (cuando la propia ficha lo indica). La ruta manual mostrada está documentada con VCDS / VAG-COM. Consulta el módulo, el tipo de codificación, el canal o Byte/Bit y los valores necesarios antes de realizar el cambio.

¿Qué hace esta codificación?

Enables trailer / towbar retrofit. Please note! For Facelift model. Adaptation in motor control unit 01 is not accepted for some models. In this case, the coding can be ignored. Control units that are not installed can also be ignored. Please note that certain coding steps must be carried out according to the part numbers installed (camera).
