MaxiDot problem

Hi, from italy.

I've a 2006 polo 9n3 (same electronics of fabia mk1 and 5j pre face lift).

I've install and coding a maxidot from fabia 2008 (5j0920841c).

All work but i've 2 error in abs modul.

I suspect is because the new cluster work with canbus 1.6 and not with k line like the original one. (Maxidot is crypted eeprom, but mine original one is not).

I suspect the problem is my BCM (6q1937049 D), and i think i need to change it with a new one 6q1937049 F.

Need your opinion and help 🙏🙏 thank you
