Volkswagen and Audi Parts Protection and Coding Notice:
For some Volkswagen and Audi control modules, component protection (CP) and coding need to be removed after installation.
Removing component protection (CP) and encoding involves advanced online authorization and firmware /EEPROM write procedures, which must be performed using the official factory diagnostic system.

By purchasing this product, the customer explicitly acknowledges and agrees:

1. Removing component protection (CP) and encoding poses irreversible risks.
2. Incorrect programs, software mismatch, unstable voltage, session interruption or unauthorized tools may all cause the module to fail to be recognized, resulting in communication interruption or the module being unusable.
