2017 VW Jetta keyless NEC 24c64+MQB couldn’t read data with cluster in service mode by pogo pin with Xhorse VVDI2, had to read eeprom and write eeprom in service mode back but after had to turn ignition on to write original file. Figured you can hotwire few fuses together to turn ignition on without key.
I did dealer key myself with data I read of a car, the key I used is Xhorse Mqb universal smart key, I’ve just put vw logo on it.
Make sure you buy one with marking XSMQB that S stands for smart
Easy Job!
