Before unlocking pcr2.1 on bench, it is advisable to perform encryption first.

For unlocking pcr2.1 via OBD, consider the example of unlocking an Audi A1 1.6tdi PCR2.1 via OBD:

Select the “unlock via OBD” option.
Read the “VR file.”
Write the “VR file” and apply the patch.
Keep in mind that the Audi A1’s battery is located in the boot, so it’s important to prepare accordingly before writing to save time.
The process typically takes around 17 minutes.
Next, proceed to the “Read/Write” option:
