Here we will show how to calculate VAG MQB48 NEC35XX immo data with Xhorse VVDI MLB Tool and MQB48 adapter.
Model example: Audi Q2.
Tools used:
VVDI MLB Tool
MQB48 adapter
Original key
A new key to be programmed
Before using MQB48 adapter, we should modify MLB tool firmware as following:
How to Update VVDI MLB Tool Firmware to Use MQB48 Adapter?
Then we start to read immo data with MLB tool.
Run VVDI MLB Tool software. Choose MQB48 function and check wiring diagram.
Select corresponding wiring diagram. Here the key board is the same as type 5.
Need to solder 2 wires, black wire and red wire.
Remove a capacitor, the solder the red wire (near the IC position).
Open the original key shell.
Remove a capacitor as shown in the wiring. Then solder two wires.
Connect Xhorse XDMQBAGL MQB48 Adapter with MLB Tool.
Connect Key board with MQB48 adapter. Place the key to coil of MQB48 adapter in the vertical direction.
The MQB48 adapter has strict power supply requirements during data collection. Use two separate USB cables to power the MLB main unit and the MQB48 collector. Do not use charging adapters.
The MLB main unit does not require 12V power.
Then connect MLB Tool with PC via USB cable.
Read key information. Read Key ID successfully.
Press Collect Key data.
Collecting key data and calculating immo data.
Calculation finished. Restore key back to original status. Save MQB NEC35XX immo data.
Data Collection Time:
Good power supply: ~15 minutes for data collection, ~1 minute for immobilizer data calculation.
Average power supply: ~30–60 minutes for data collection, ~1 minute for calculation.
Resolder the capacitor back to the key. Reinstall key shell. This is very important !!!
NOTE:
Removing the wrong capacitor can cause the MQB chip to become unrecognizable, making it impossible to collect data.
After reading the data, the capacitor must be restored; otherwise, the key cannot be programmed to car.
If need to connect MLB tool with key tool plus to calculate MQB48 immo date, make connection like this:
Note: Tablets with a single Type-C port have poor power stability, leading to longer collection times and lower success rates. Strongly recommend using a PC.
Connect VVDI2 or VVDI Key Tool Plus with vehicle via OBD connector.
Go to MQB anti-system system (NEC35XX Continental/VDO), read cluster info.
Load immo data saved by MLB Tool.
Then generate dealer key and learn key.
Problem:
Successfully add a spare VVDI MLB key to an Audi Q7 2019 using VVDI MLB Tool and vvdi2.
After programming,press the buttons of the key, the light turns on for 3-4 seconds and then goes off.
Solution:
In VVDI MLB Tool software, go to Update Online->Upgrade OEM keys to update VVDI MLB key and try again.
