The first letter of the external VIN after “WDB” gives the body style, like The internal VIN of this car (e.g.w211): is WDB2110261AXXXXXX Yes, you can make OFFLINE coding with your system and then go back to the dealer and ask them to make an SCN coding for you…however are u sure they will not charge you the same amount as if it was done in their workshops ? The only good point here is the time needed to do this. I’m not aware of any car which can be OFFLINE coded without the request for an SCN code. If you have to make an Offline coding this implies to flash your unit with an updated software version or at least the same version which you have already (not sure if you will be able to downgrade your software) and then SCN code that one to be activated in your car. Coding does not imply that you have to replace your unit software completely. Let’s not confuse OFFLINE coding with simple CODINGS !Ĭodings can be done with regular DAS or Developer DAS more deeply. 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. SCN or CVN coding was added to the cars back in 2003 if not earlier.
