3.Xhorse Multi- Prog/VVDI Key Tool Plus Pad
- Multi-Prog+ VVDI2+ Xhorse XDMPR8GL MQB-RH850/V850 Adapter
- Xhorse Key Tool Plus+ XHORSE XDNPR8GL MQB-RH850/V850 Adapter
Note: the adapters used for Multi-Prog Programmer and Key Tool Plus are different.
To read MQB RH850 clusters, you need to activate MQB license to the key tool plus. Multi prog has the MQB license built-in.
Function:
Read IMMO data
Make dealer key
Add new key
MQB-RH850/V850 Adapter Supported Dashboards:
WW 4th Gen Johnson Controls 34××series
MQB 34××series
MQB-RH850 (R7F) series
Xhorse Multi Prog+ VVDI2+ Xhorse XDMPR8GL MQB-RH850/V850 Adapter
STEP 1: Connect devices, dashboard and PC
Run Multi- Prog software
Select Device>> dashboard number>> Detail
Check the connection diagram
Use a tweezer and heat gun to remove the 8 capacitors according to the diagram
Scrape the PCB mask before soldering the GND wire to the soldering point
Solder the wires of Xhorse MQB RH850/V850 Cable to the corresponding position on the dashboard PCB
Secure the wires with acetate tape
Connect the MQB RH850/V850 Adapter to Multi-Prog Programmer, and connect the Multi-Prog and VVDI2 Programmer to the PC by USB cables separately
Don’t forget to connect the 12V power supply
STEP 2: Read chip data by Xhorse Multi Prog
After connection, select “Crack Reading” to decode the chip and read the chip data.
Save the file after reading
STEP 3: Read IMMO data, make dealer key and add key by Xhorse VVDI2
Run VVDI2 software and select “VW”
Select Key Learn>> MQB platform instrument immobilizer>> Instrument with locked NEC35xx (MQB48, VDO/JCI)

In practical use, we need to enter the corresponding options and operate according to the instructions in the connecting diagram. In the subsequent steps, we will complete the operations of removing components, soldering the cable, connecting the cable and KEY TOOL PLUS, reading, calculating, etc.
Detailed operation guide:
Tap IMMO Programming>> VW>> Select by type>> MQB instrument immo system>> Instrument- MQB (VDO/JCI-NEC35xx lock)>> Start programming>> Programmer reads files>> Obtain immo data
STEP 1: Programmer reads files
Select Read NEC35xx/RH850 chip>> Wire bond>> the corresponding dashboard number
Follow the connection diagram to remove the components required, and use a tool to connect the cables of Xhorse MQB-RH850/V850 Adapter on the MQB chip, and then connect VVDI Key Tool Plus Pad and MQB-RH850 Adapter as well.
Make sure the Xhorse Adapter and chip are in good connection
Read and save the chip data file
STEP 2: Obtain immo data
Load the chip file just saved to calculate the IMMO data
It will take about 5-10 minutes to calculate according to the network situation. Just keep patient and wait until the process is completed.
After calculating the IMMO data, save the file.
The IMMO data can be used to generate dealer keys and for key learning with Key Tool Plus.
Note: Some dashboards like D70F3426 also need to add additional operations to read EEPROM data.
In sum:
Xhorse supports MQB RH850 5A clusters IMMO programming. Need soldering and removing components.
Yanhua ACDP supports RH850 5A cluster IMMO & Mileage, 5C mileage function. It has a set of interface boards and does not lift pins, no wiring, no soldering.
CG100X only supports RH850 5A mileage repair, it cannot read IMMO data.
