Xhorse VVDI Key Tool Plus can now support to add 2018 Volkswagen Beetle MQB48 key successfully. Need to activate VW MQB License and remove immo box from vehicle. There are 2 ways can access to immo data: lift the pin from PCB or cut pin connections. This will require an experienced technician.
How to read & unlock MQB IMMO data?
Here’s reading VW MQB48 NEC35xx as an example.
Please ensure a stable network during whole process.
- Read & Save MQB Data
Immo programming >> VW >> Select by type >> MQB instrument immo system >> Instrument – MQB48(VDO/JCI- NEC35xx locked) >> Start programming>> OK >> OK >> Read IMMO data >> Use the programmer to read data directly
Here can check the wiring diagram for 2 ways:
Lift the pin from PCB or cut pin connections. Cut pin connection maybe a little easier.
- Lift The Pin From PCB
Step1. Locate the pin to be lifted(FVDD) according to wiring diagram.
Step2. You need to use a heat gun to assist: set the temperature to 355℃ and the wind to the minimum, point the muzzle of the air gun at the pin to be lifted.
Step3. Wait for the pin to be heated, insert a blade into the bottom foot, gently lift it up. Pay attention to the pin not lifting too high and ensure that it leaves the PCB.
Step4. Wait for the pin to cool, weld a thin wire or varnished wire from the pin, use adhesive paper to secure it on the backside to prevent shaking.
Step5. After reading MCU, remove the welded wire from pin(FVDD), press down on the upswing with a tweezer, then heat the pin to weld to PCB with electric iron.
- Cut Pin Connections
Step1. Locate the pin connections to be cut according to wiring diagram, cut lines according to the marked position and shape.
Step2. Do not use too much force when cutting, cause it may damage the circuit under PCB.
Step3. After cutting, check the FVDD test points and other points are disconnected.
Step4. After reading MCU, the cut position needs to be restored.
