Hey ,

I am trying to move CS from red tiguan cluster to color cluster , or any other "old" style 6 byte CS systems Golf,Jetta, etc and write them to a new 2013 + cluster.
The problem I have is I don't understand how the 2nd part of the 12 byte CS is generated. The first part is the normal ECU CS 6 bytes but I don't understand how the second one is linked.
If I write a random value the key does not work , if I just create a key for the "new" cluster the cluster is fine so my tools can write IMMO , I just don't understand what is the deal with the 2nd 6 bytes in CS.

I have original Carprog , VVDI , VVDI2 and I can get SMOK if needed but it should work with these at least.

Cheers,

As discussed yesterday, your problem is a faulty immo block.
Some data (mainly Status and Config) didn't hold sensible values.
