Method for coding new battery in 2015 Audi Q5

I’m getting ready to change the battery in my 2015 Audi Q5 2.0T. I see in some of the examples there are 3 ways to do this. Can someone tell me the method I use for my Q5.

Thanks,
Manuel

Without seeing an Auto-Scan, I could only guess, and I would rather not do that.

Turned out to be CAN gateway using CAN. Worked without any problems.
