Purpose and function of the module

The right-side LED DRL control module is responsible for powering and controlling the operation of the LED diodes in the daytime running light, maintaining proper lighting parameters and cooperation with the body electronics. A properly functioning controller:

• ensures a stable light beam for the right daytime running light,
• reduces the risk of lighting errors on the instrument cluster,
• supports the correct operation of safety functions related to vehicle visibility.

Thanks to its dedicated design for a specific side of the vehicle, the module maintains the correct mounting geometry and compatibility with the electrical wiring harness.

Compatibility and vehicle integration

The offered controller is a component intended for use in the Audi Q5 8R generation model, integrated with the factory LED DRL lighting system. As a part from the Headlamp ballasts and igniters category, it works with the original lamp and electrical installation, which facilitates installation and limits the need for additional modifications.

The module is prepared for operation on the right side of the vehicle, which is significant both in terms of construction and the logical assignment within the lighting control system.

Performance characteristics and advantages

As a component originating from an Audi vehicle, the controller maintains factory operating parameters and is optimized for cooperation with the manufacturer's electronics. Key benefits include:

• consistency with the original lighting system – no need to adapt universal solutions,
• preservation of the factory lighting characteristics of the LED DRL lamps,
• the ability to restore full functionality of the right daytime running light after the failure of the previous module,
• reduction of the risk of conflicts with body electronics due to the use of a controller from the same product line.

The used nature of the component allows for an economical repair of the lighting system while maintaining proper operating parameters.

Professional installation and diagnostics

Due to its role in the lighting system and integration with the vehicle's electrical installation, installation by a workshop with experience in working with Audi electronics is recommended. Proper installation of the module on the right side of the vehicle and any necessary adaptation in the diagnostic system allow for avoiding lighting errors and ensure stable operation of the LED DRL lamps.

In the case of vehicles where problems with charging or power supply occur simultaneously, it is worth additionally verifying the condition of the electrical system.
