Stop in for a cup of coffee

So @Tooljunkie , what is the best scan tool to change the rear brakes on my 2016 Audi Q5?
Not sure. My snap on solus will do it,and its only $4200.
I was given the impression most of the electronic calipers can be serviced without a scan tool. That being said if it slams shut on your fingers dont blame me!
Referring to the fsm may give you some insight.
