Here you will get the answer to question “VW Tranporter 2017, Can VVDI2 do it? What are the steps?”
T6 is till 2019 always uds dashboard.
But use 2 different transponders.
Some are id48 annd some are id88.
I try an couple with vvdi but there is an bug i think.
Cus vvdi can enter service mode and see all data.
But if the dash is equipt with id88 it cant precode the key.
If dash have id48 no problems.
P.s. the dashes what use 88 abrites avdi can do it without problem
