VW key programmers to use:
add a spare key mqb
the system is Smart key
The first time trial: Failure
Xhorse VVDI2 recognizes that car has Johnson Controls dash but can’t retrieve data. I put Vag OBD Helper cable on and did online calculation.
I put the immo data from Vag Helper into VVDI2 but that’s as far as it goes.
Am I able to add a spare key ??
It worked finally:
step 1 : read car with OBD Helper
Step 2: precode key with VVDI2
Step 3 : learn all keys to car.
I was able to add a key to a 12/2018 Golf 7 with JOHNSON CONTROLS as well as a 11/2018 Golf with a VDO NEC35XX. Both cars would not identify with the VVDI2 but I was able to make it happen with the vag helper cable.
