There's a recode option in VAG-COM...
and there is a section in the Bentley manual that has the coding options.
For example, a ATW motor will have:
07701 for quattro manual
An AWM motor will have:
16201 for quattro manual
16701 for quattro manual w/ ESP
For AEB:
06301 for quattro manual
06201 for quattro manual w/ traction control
The first two digits are country/emissions
The third is drivetrain/options
the fourth is transmission (0 = manual)
The last digit indicates the vehicle type (1 = A4)

That's the weird part about recoding. I wonder what really happens...
I wonder if by any chance, I already have fuel and timing maps of an S4 in my 12V? oh wait, they didn't exist back then
