Some control units when replaced require initial startup once fitted, by using a Xentry DAS computer. I have noticed some require software updates to the control unit, downloaded from online servers also, before you can carry on with the basic coding and initial startup. Is there a way to bypass this on the original dealer systems, or can this only be done on an offline/cracked system?

Can we bypass the whole check and update for new software thing? Or it has to be done as part of initial startup?
