That is our solution.
Its possible only if VGS1 (with MPC555)
VGS2 is Tricore TC1765
VGS3 is Tricore TC1766
For TC not possible cloning, because of OTP Area (same as EDC17)
Best way to solve VGS2 and VGS3 is:
Reset it first with:
MBCan
http://www.autodijagnostika.biz/prog...an-reset-tool/
After reset is done, you must check what is original version of Software 00xxxxxxx
Then you download CFF file from
www.cff-database.com
And you flash new unit with xxxxxxxx_0001.cff file
Now you have new VGS
-reseted
-same software version
Next step put it into car, make personalization and activation.
If all ok, job done.
If not ok, variant coding must be made. (Variant: XYCC)
You need VGS-NAG2-ALL.CBF , load it to vediamo, connect to 7G then change coding.
To check correct variant coding you need to connect old 7G and read 4 variant coding letters.
