Xentry there is no offline programming, only online. Then if we need to go online with DAS we switch the modified flash folder to the original. If you set it up correctly, you can program offline in DAS only. DAS is your way to go.ĭAS (older models before 2011, but still most cars communicate through this program) Noe that: For those with Star diagnosis for 100usd around. and there is free offline programmingīetween those three options, vediamo is the best and can be used for 99% vehicle’s model If you want only for 204.041 as above, you can try to use 204 in DAS. Vediamo is the way to go to program ecu offline and is used by daimler factoryģ. (In xentry, you have to buy xentry calculator.)Ģ.
If you want to program ecu ‘offline’, there are several options:ġ. It is much easier to find this if you enter the external VIN to EPC and let it decode the internal VIN for you. – position 9 is a check digit and the tenth digit comes from the model year. – next digit is about the SRS system, I’ve found explanations up to the letter F, so this car must have more SRS equipment than known when my reference was drafted – next two digits are the model within the body type, seems to be a direct copy from the internal VIN 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. Mercedes offline programming/coding tips and guides:
