Purpose and function of the module

The presented module is a factory solution dedicated to the Volkswagen Tiguan Mk2 model, responsible for operating the AUX port and two USB connectors in the console. As an element of the infotainment system, it works in close cooperation with the multimedia unit, ensuring stable data transmission and power supply for mobile devices. The AUX port allows for a wired connection of an external audio source (e.g., a player or phone), while the dual USB enables simultaneous charging and data communication – e.g., for playing music, integration with the vehicle system, or updating selected multimedia functions.

Advantages of using an original module

Using an original module in the Tiguan Mk2 ensures:

• a perfect fit for the electrical installation and the Volkswagen multimedia system architecture,
• stable operation of the AUX port and both USB sockets without the need for additional adapters,
• aesthetic integration with the factory finish of the center console,
• maintenance of functional consistency with other electronic control modules in the vehicle. For the user, this means convenient access to device charging, wired audio, and phone integration with the car's system, without compromising connection quality.

Technical characteristics and vehicle integration

The module belongs to the Electronic control modules and controllers group, which means it communicates with the vehicle's bus and infotainment system in accordance with the manufacturer's standards. The design is intended for installation in the factory-prepared location in the Tiguan Mk2 console, using original wiring connectors. As a used part, the module comes from disassembly and is intended for reinstallation in a vehicle where restoring the AUX/USB port functionality or replacing a damaged socket is required. Proper selection based on the OEM part number and replacement numbers allows for maintaining full hardware and software compatibility with the specific car configuration.

Practical installation and operating tips

When replacing the AUX port module with dual USB, it is worth paying attention to:

• compatibility with the multimedia unit used in the specific Tiguan Mk2 unit,
• correct connection of the wiring harness to the factory connectors,
• gentle seating of the module in the panel to avoid damaging the AUX and USB sockets,
• the potential need to verify the operation of all functions (charging, data transmission, audio) after installation. Such an approach minimizes the risk of mobile device communication issues, charging interruptions, or audio signal interference, thereby increasing the comfort of daily vehicle use.

Support in selecting used electronics

In the case of modules from the automotive electronics group, it is particularly important to match them correctly based on part numbers, hardware and software versions, and vehicle equipment configuration. To better understand the principles of selecting and installing such components, it is worth using the guide: Used automotive electronics – ECU modules and second-hand sensors in practice. If you are planning a comprehensive repair or upgrade of the multimedia and mobile device power area in your Volkswagen and need other elements from the same group, such as control modules, controllers, or additional electronic units, check the available parts in the Volkswagen electronic control modules and controllers category. Additional information on when choosing used VW components is particularly cost-effective is provided in the guide: Volkswagen – solidity and reliability versus choosing used VW parts, which discusses, among other things, compatibility issues, example applications, and practical installation tips.
