Technical specifications:

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.
3. The Seller shall not be held responsible for any damage, malfunction, loss of communication or failure resulting from the removal of component protection (CP), coding, programming or vehicle system adaptation by the customer or any third party (including Audi dealers, workshops, modifiers or mechanics).
4. Any malfunction that occurs after the removal of component protection (CP) and coding is regarded as third-party technical damage after delivery and does not constitute a manufacturing defect. It does not meet the conditions for return, refund or replacement.
5. Special Note: If the customer requests the seller to remotely flash data and code for product coding and to remove component protection, please contact in advance. The remote cost will be calculated separately (the seller is responsible for any damage caused by this remote flashing of data and code).
