How to: program VW Passat B7 ID48 Key using Xhorse VVDI Prog+ VVDI2.
Here we have a working key so need to add a spare key. The easiest way is to clone ID48 transponder with vvdi mini key tool. Here we did it with vvdi prog and vvdi2 because have no id48 token. Same procedure if all keys lost.
Run VVDI2 software->VW->4th Immobilizer system- VW/Skoda/Seat->VW Passat/CC Key Learn
Select OBDII Read Login Code+ Part memory data
You can read engine ECU, get PIN, CS
Switch ignition OFF, then switch ON
security access failed, vvdi2 cannot read the login code for current ECU.
So we need to remove comfort module to read eeprom
Remove comfort module, read m95320 data with vvdi prog
Save original dump
Assemble the comfort module and install it back on the car.
Go to VVDI2 again
VVDI2->VW->4th Immobilzier system- VW/Skoda/Seat->VW Passat/CC Key Learn->Load Comfort Module EEPROM (95320)
Upload eeprom just saved
Select Get PIN, VIN and search 7 bytes CS from dump file
decrypt 95320 dump file
Input number of keys to learn: 2
Select Key Learning
Press OKAY button to start learning. Insert dealer key into car and switch it on for at least 2 seconds.
Then change next key within 5s.
Learn key successfully
New key will start key successfully.
You need to program the ID48 chip or the transponder separately.
The remote should be adapted separately.
