b'Different how, you ask? Well, lets start with the age-old frustration of all independentsWith the VW/Audi ODIS system, the guided fault-finding function of this tool takes all (meaning non-Volkswagen dealer techs) when trying to scan module data using either factoryof the confusion away. Guided Fault Finding (GFF) and Guided Functions are a tools, but especially when using aftermarket scanners: the dreaded Measurement Valuefabulous way to navigate any Volkswagen or Audi coding or SVM programming event.
