Just a quick guide on how to read immo data from BCM(Body Control Module) for key programming. Here I'm going to use Xhorse VVDI Key Tool Plus & BCM2 Solder-free Adapter to program 2013 Audi all keys lost.

Step1. Read Immo Data
Immo programming >> Audi >> Select by type >> Fifth immobilizer system >> Start programming >> Read BCM2 Data >> Prog read - unencrypted BCM2 >> Read BCM2 data
This operation will use prog to load P-FLASH and D-FLASH files in turn.
Click "OK".
BCM2(D70F3634)(Adapter - Welding free)
Follow the diagram to connect Key Tool Plus, BCM2 Solder-free Adapter & module.
Read >> Continue
Reading success.

Read P-FLASH successfully, click "OK" to read D-FLASH.
Read >> Continue
Reading success.

Step2. Obtain Immo Data
Immo programming >> Audi >> Select by type >> Fifth immobilizer system >> Start programming >> Read BCM2 data >> Load D/P Flash to obtain immo data

This operation will load P-FLASH and D-FLASH files in turn.
Click "OK" to start loading.
The p-FLASH file is loaded successfully.
Click "OK" to start loading the D-FLASH file.

VIN, CS, and key ID have been read out.
Read the data successfully, and click "OK" to save the data!

In the immo5 system, BCM2 data can make dealer key and learn key!






Step3. Make Dealer Key
Click "Make dealer key".
If you want to prepare an OEM key, make sure the new key supports change ID(most 3rd part keys do not support this)
If you want to prepare an OEM key, connect the device to the car and switch the ignition on.
Do you want to prepare an OEM key? (OEM key can enter dealer service shop)
Click "No".
A4L, A5, Q5 add a key or lost all key - Don't need a working key
Press OK to load the BCM2 data read in step 1.
Load file success.
Put a key into the programmer, then continue.
Now reprogramming key info, please wait...
Writing data, please wait...
Make dealer key success.
Done.
