Accidentally wiped my CGW?? 06 CLS55
In trying to troubleshoot throttle issues with no success for 6 months so far I thought id try resetting the CGW through ASSYST, to which my xentry scanner did not seem to complete right (no access to xentry online and xentry helpdesk) and now the CGW is uncoded and has no software information. Would anyone be able to point me in the right direction on where to get the software and project files for my car/cgw and program it back? Coding a w211 CGW with the same numbers as mine got things communicating again but without that C219 base software it will randomly immobilize itself and none of the CAN or any other codes make sense.

May need to flatbed your car to the dealership. They can obtain original coding from MB servers in Germany and reload original configuration files.
You are the second person I am aware of who bricked their CGW.
It sucks, yes, but STAR/Xentry developer kit warns one to tread carefully when coding modules or "bit banging" in them.
Let us know how this is resolved.
@UncleBenz55 any input?

I was able to use videamo to re-program it, albeit with different software. I did not know you could save any scanner settings, and ive coded it to the best of my ability. I recall saving something prior to wiping it, not too sure what it was but I thought it would be better to save than not. SDFlash offline was not present which is why it was bricked, that and poorly worded warnings beforehand. Currently still in the hopeless search for my actual issue, that being random drive auth issues (the random immobilization still), CAN issues, and no throttle movement. Its been so long since I started trying to diagnose this issue, and I keep coming across minor issues along the way and repairing them. All this chasing of CAN wiring and grounds has been a headache, and it looks like im only getting started. The car has not driven propperly in 7 years if im reading off odometer records, it has sat since at least August of 2018. Any suggestions would be great
