Audi A6 4F Instrument Cluster, VAG-COM.

Hello,

It's about a 2005 Audi A6 4F Avant 3.0 TDI quattro with full equipment.
The interface is the HEX-CAN-USB from dieselschraubershop.

After my acquaintance's instrument cluster was incorrectly coded, as described HERE, we managed to enter a different coding.

From that point on, we were able to code everything (the reason was to disable the seatbelt warning).

Unfortunately, it is no longer possible to enter a coding value greater than 2000xxx. VAGOM 504 indicates that only values up to 1478xxx can be entered.

According to the table on de.openxxx.org, his A6 would result in a number greater than 3,000,000. Therefore, we need to display the Avant as a sedan in the onboard computer, because we can no longer add the number 1024 to the first four digits of the seven-digit number.


Do I need to use a different version of VAGCOM, or does anyone else have any ideas?


[edit: It didn't work with 512.1 either.]

Thank you for the information.

There should be a file named 'CodingLog.TXT' in the 'DEBUG' subdirectory. Please send it to me.

Hello everyone.

Thanks to your great support, the problem has been resolved.
The solution should be written by Sebastian or Uwe; I don't want any unofficial information to be shared here.

Thank you again to the two of you, and great praise for the wonderful work.

Thank you . We are, after all, the official Ross-Tech distributor.

The problem is that Audi has decided to slightly extend the coding, meaning a few more bits have been added. VAG-COM version 512.1 cannot yet handle this, but version 512.2 will also be officially available soon.
