Hello,

i have installed xentry das 12/2017 with developer Option.
I want to update engine ecu software in an mercedes cls 350 from 2005.
There is only an online flash modus to do that.
Is there any possibility to activate offline flash modus for updating engine ecu software ?

Many thanks

Hello,

now i have installed xentry 03/2018 from persona with all secrets here in this forum.
I have now enabled offline programming for ecus.
I have one question.
Is it necessary to scn code the engine ecu ???
I can read out the codings from the engine ecu and then manually change the codings in developer options after engine ecu software update.
Can i do it in this way ?

regards
