Problem:
Mercedes W204 used ELV adaptation with CGDI MB.
hi i need some help...i saw the tutorials but they seem contradicting...i wiped second hand w204 elv...then wiped the eis...wrote back the saved data and then synced the evl from the eis tab...only when i read the evl data all seems in order but the activated tab remains unticked....is that typical or am i doing something wrong?
Solution:
It is so simply.
1. read EIS and get key password, save the EIS data.
2. wipe both ELV and EIS
3. write EIS data to EIS (don't insert key after write completed)
4. sync ELV with EIS
5. insert key, that will activate both EIS and ELV.
