Mercedes W221 Central Gateway CGW problem
Hi,

My car (W221-2009) still can runs with most of the functions working except adaptive brake and voice control.
I check and see that the Central Gateway is defective.
I have DAS/Xentry 2012, 2018, 2019 with developer mode and a clone C4.
I think the CGW need to be fixed to bring back it original status or restore/reset it to its original data. I also bought a used CGW with same part number.
What should I do? What tools or programs do I need? If I have to learn how to do it then is there any school/resource that I can learn?

Many thanks in advance.

Regards,

How do you know the new part has too old SW? Or did you actually mean off-line version coding instead of programming?

OP, how did you conclude the CGW is broken?

If I need to change the VIN number of the used one that I bought (not the original one) can you teach/show me how to do it?

I do not know if the part has too old software but I assume that if I can update the software successfully then the CGW will back to normal.
I tried with Adaptation but DAS shows that there is no new software version for the module.
I can not 100% the CGW is broken but what I get from DAS saying it is defective so I assume so.
Thank for reply. Do you have any clue that where should I start?
