Audi TT Factory Option Retrofit Review

Enhance Your Audi TT with Factory Option Retrofits

While many modern vehicles come equipped with advanced safety and convenience features, some premium cars, including certain Audi TT models, might not include every desirable option as standard. This is where the appeal of factory option retrofits, often referred to as OEM options, comes into play. These upgrades allow owners to enhance their vehicles with genuine manufacturer parts, bringing them up to par with higher trim levels or adding functionalities that were previously unavailable. This review delves into the process, benefits, and considerations of installing OEM options, specifically focusing on a common and highly beneficial upgrade: the blind-spot monitoring system (BSM) with wide-angle mirrors.

Understanding OEM Options: Blind Spot Monitoring for the Audi TT

The primary goal of installing OEM options is to integrate features seamlessly, as if they were factory-installed from the beginning. For the Audi TT, a popular retrofit is the addition of a blind-spot monitoring system. This system typically consists of two main components: wide-angle mirrors and S-RADAR sensors. The wide-angle mirrors replace the standard side mirrors, offering a broader field of vision and significantly reducing blind spots. This visual enhancement alone improves lane-change safety. When combined with the S-RADAR sensors, which are discreetly mounted inside the rear bumper, the system provides both visual and audible alerts for approaching vehicles in the rear blind spots. A key feature of the S-RADAR sensors is their ability to detect only moving objects, minimizing false alarms from stationary items and focusing on genuine hazards during lane changes. These sensors typically detect vehicles within a 5-7 meter range, providing ample warning time.

Installation Process: Integrating OEM Options

The installation of OEM options like the blind-spot monitoring system on an Audi TT is a precise process that requires specialized knowledge and tools. It's important to note that this specific installation was performed in South Korea, and the cost is presented in Korean Won with an approximate USD conversion. The process generally involves the following steps:

1. Component Removal: The original side mirrors and door trims are carefully removed. Electrical connectors are disconnected, and mirror mounting bolts are loosened.
2. Wide-Angle Mirror Installation: The new wide-angle mirrors, identifiable by a triangular marking, are installed in place of the factory mirrors. Precise alignment is crucial to ensure optimal visibility of the blind spots.
3. S-RADAR Sensor Mounting: The S-RADAR sensors are mounted internally within the rear bumper without causing any damage. The angle of installation is critical for accurate detection.
4. Wiring and System Integration: Sensor wiring harnesses are connected to the vehicle's electronic control system. This includes connecting the LED indicators in the mirrors and the S-RADAR sensor signals. Wiring is meticulously routed through interior trim for a clean finish.
5. Testing and Finalization: After wiring, a comprehensive system test is performed. This involves checking the visual alerts (LEDs in the mirrors) and audible warnings by simulating vehicle movement. Once confirmed, the door trims are reinstalled, and a final inspection ensures all components are secure and functioning correctly.

The entire installation process for this OEM option typically takes about 2-3 hours and can usually be completed within a single day. The cost for a basic set, including wide-angle mirrors and S-RADAR sensors, ranges from approximately 2,500,000 to 3,800,000 Korean Won (roughly $1,800 - $2,800 USD, depending on exchange rates). Additional features, such as integration with a digital rearview mirror, would incur further costs. In terms of durability, the sensors generally come with a 2-3 year warranty. While the wide-angle mirrors require no special maintenance, keeping the rear bumper area free of excessive dirt can help maintain optimal sensor performance. The S-RADAR sensors themselves are designed for longevity, and replacements are rarely needed, but if they do fail, the unit replacement cost can be significant.
