Menu path:
Select by type->Immobilizer->MQB Immobilizer system->NEC35XX Dashboard->2015-> Read IMMO Data
NOTE:
Yes for vdo continental. If it is JC cluster, it is not supported.
JC cluster you need to disassemble the dashboard and read it on the table with the vvdi programmer or xp400 pro.
Nec35 locked JC cluster you need to do it on bench via vvdiprog. MQB solder free Adapters are cleaner and easier to use.
