Audi Q7 Hitch retrofit - Engine Long coding

Hi,

I have just completed my 2012 Q7 Factory Hitch retrofit and I was able to code all modules except the 01 - Engine module. There is no Long code helper and I really don't know what to input.


Here is a scan of this module:

Address 01: Engine (CJW) Labels: None
Part No SW: 4L0 910 551 K HW: 4L0 907 551 A
Component: 3.0l V6 TFSI 0040
Revision: --H08--- Serial number:
Coding: 0121000A290F0128
Shop #: WSC 58560 000 1048576
VCID: B02C506C236297C2F9-80E4

Anyone knows what to change? And by curiosity, anyone know what the coding does on the Engine module?

Thanks
