Thanks Lamda1 ,
i can read both ISN from CAS ,and i can read DME dump as well
how do i put CAS ISN into DME and will the car start afterwards or do i need another software to
finish up ?
thanks

Car starts when ISN matches 100%. It would be nice to program it to the car (VIN, correct tune, clear adaptation and taught versions) but the car will start anyway.

Put both here, files from cas and dme.

As I know cas 3 is ews4 system and there is 16 bytes Sekret Key to synch CAS with DME.

Certainly this car uses long ISN. I don't know how to find it in the ECU dump.
Do you have the CAS that came with the ECU?

No i dont have the CAS
I bought the ECU separately

Read the DME ISN and write it to CAS. This is the easiest.

Here is a complete set with Ktag Full ECU backup and CAS3 + and ISN

One of the two ISN in text file is the right one but i forgot which one is the real one.

write full ecu dump to your ecu and write cas eprom and flash to your cas3 make key with tango using one of the ISN provided and start car

Pass in PM

Full backup with known ISN, nice idea! But why not modify the original CAS with this known ISN, so that the original keys still work?

Thanks so much bro ,
But that means i have to write new key to CAS3
using your file .
let me know if i am correct so i can go for new key and write .
thanks in advance
