How to Program VW MQB48 VDO/JCI with NEC35xx Chip by VVDI2+ VVDI Prog?

Here is the tutorial to use Xhorse VVDI2+ VVDI Prog to add new key/all keys lost on VW MQB48 VDO/JCI with NEC35xx chip

 

What is required?

Click here to check the Xhrose MQB license activation guide.

Note:

  • Add key and all keys lost all require to read immo data with VVDI Prog/Key Tool Plus first. AKL also requires sync data from third party.
  • If you have a VVDI Key Tool Plus Pad full configuration, register it and activate MQB license, then you can use it to read IMMO data and program key directly.

 

How to operate?

Step 1: Read MQB data with Xhorse VVDI Prog

Step 2: Decrypt IMMO data to add key with Xhorse VVDI2

 

Step 1: Read MQB data with Xhorse VVDI Prog

Remove the instrument cluster

Unscrew all screws and disassemble dashboard

Take out the circuit board

Locate MCU chip type

There are two methods to read MQB data

Method 1: by Lift PIN diagram

Follow the wiring diagram to connect dash with VVDI Prog via MCU V3 cable

Read immo data

Wait 3-5 minutes till the process is completed

Save data

Method 2: by Cut PIN diagram

Reinstall dashboard and use the second method

It might only be for that particular dashboard, probably not all will have track cut method.

It requires opening the reverse side of the circuit board.

Cut the junction with a scalpel blade and magnifying glass

Then follow the wiring diagram to connect dash with vvdi prog via mcu v3 cable

A white feeder wire needs to be connected to the back of the circuit board

Read and save IMMO data

Connect the junction and reinstall dashboard. And move to step 2.

 

Step 2: Decrypt IMMO data to add key with Xhorse VVDI2

Connect VVDI2 key programmer with laptop and make sure network connection is enabled and keep normal

vvdi2 vvdi prog program vw mqb48 nec35xx chip 13

Run VVDI2 software

Select Key Learning>> MQB platform immobilizer>> Dashboard- MQB48 VDO/JCI-NEC35xx LOCK

Click Decrypt IMMO Data

Pay attention to the on-screen note and click Yes to continue

Upload the MQB IMMO data just saved in step 1

Then VVDI2 will decrypt immo data online, calculating online in process.

Save the immo data decrypted

And then you can use it to add new keys.

Note: All keys lost requires the third-party cooperation to sync data.

 

Alright! That’s the whole process to read VW MQB IMMO data with Xhorse VVDI Prog and decrypted data to add keys/all keys lost with VVDI2 key programmer.
