Power class - HELP

[mcaris25]

I copied in external programmer because FVDI 2018 cannot read data from the Skoda Octavia II 2012 dashboard.

data in the photo read from the ECU 16u34 and saved a new dashboard. Red color:
- CS 7 bit?
- power class
- new key.

Original key 3cdbd72a saved in das 1z0920843S and ecu 16u34. I added it manually.
Can bit 7 be read from this key?

Wrong, ECU has 6 bytes out of 7 byte CS. Last byte in ECU is always 00.

[H2Deetoo]

If you use data extracted from ECU then you have only 6 CS bytes.
Keys are programmed with 7 CS bytes, and you don't know this 7th byte.

Also it doesn't matter because you upgraded to a VDO NEC cluster which uses 12 bytes CS.
So fill in all immo from your ecu, also the 6 CS bytes, then add 6 random bytes to make it 12 in total.
Then you *must* learn new transponders to match the cluster.

That's it.

[H2Deetoo]

I see some problems:

- Your MAC is wrong. It should be: F2983232
(AVDI has bugs)
- Your AVDI is not allowing you to enter 12 CS bytes, you have either selected wrong cluster type or it is a buggy version of AVDI.

And remember, you must adapt new transponders in this situation!

I'm glad you fixed it! What H2deetoo knows is incredible !!! It helped me a lot !!!


Sorry I'm asking here ... but they talk about power class and maybe you can help me .... I'm trying to locate in a VW G6 marelli dashboard with NEC + 95320 part number 5U0920830A the power class in the eprom ... I think in somewhere in the eprom is unencrypted ... what is encrypted is the CS, the rest I don't think ...
Do any of you know the address on the Power Class eprom?
Thanks and sorry for the inconvenience
