This is a tutorial on how to read MQB dashboard data to add keys using Xhorse VVDI Key Tool Plus. Before using this feature, make sure you’ve activated Xhorse VAG MQB License and the IMMO database on Key Tool Plus has been upgraded to the latest version.
Preparation
Read VW MQB NEC35xx Data
Now we’ll need to read the chip data on the PCB board.
Immo programming >> VW >> Select by type >> MQB instrument immo system >> Instrument – MQB48(VDO/JCI-NEC35xx lock) >> Start programming
Before we read data, please read the disclaimer carefully, make sure you’ve fully understood and agreed with the contents and responsibilities.
OK >> OK
Programmer reads files >> Read NEC35xx chip
Check the wiring diagrams carefully and locate the one that is same to the dashboard MCU. Follow the on-screen instructions and finish the operation.
Lifting Pin from CPU Instructions
Apply some scaling power onto the pin we’ll lift later.
Now we’ve finished the pin lifting.
Then we follow the wiring diagram and solder the MCU cable. Connect VVDI Key Tool Plus with the module via DB15 cable.

The whole process is gonna take 3-5 minutes.
