• maintaining consistency with the factory configuration of driver assistance systems,
• proper cooperation with the vehicle's software and communication network,
• stable operation of the rear right lane change assist function,
• reduced risk of communication errors between controllers.

This solution is particularly important in modern Audi models, where many safety systems are closely interconnected and require compatible electronic components.

Component Characteristics and Condition

The module belongs to the Audi brand and is classified as a used part, allowing for an economical yet technically sound replacement of a damaged controller in the vehicle. The product comes from the original parts line, thus retaining factory operating parameters and being ready for integration with the existing electrical system and diagnostic systems.
