using google, I found some posts with someone writing engineeringmode pass is just 2008.. .

Is this correct for some former version of these tools ?
Does anyone know the version where it's applicable ?

 

Not so in IDS/SDD to the best of my knowledge.

 

There is the knowledge how to Enbale Engineering Mode on WDS. It only provides (AFAIK for XK8) setting ECM/ECU "Channels" data. Seems so deep and factory only level knowledge required.Likely people just would brick their cars while messing around. So I don't release exact information how it can be done.
