In both cases an SCN or CVN coding was required. The idea of OFFLINE coding was to be able to make SCN codings when you don't have an internet connection at your workshop to be able to perform this online. It is a lot cheaper to ask an MB workshop to SCN code the car than keep the car in their workshop for hours and have it SCN coded.Īs far as I know SCN or CVN coding was added to the cars back in 2003 if not earlier. This was shortly discussed at another thread but first of all, why would it not be useful with a later DAS release for those cars and control units that it used to be available on an earlier DAS release? The assumption must have been that SCN coding was not needed after the SW update (either version code manually or the settings remain unmodified an valid).Īnother example could be telematics updates that may take hours.
