The 8V0998474A module is an LED control module for the headlights of some Audi vehicles, particularly the Audi A3 (model 8V, facelift from 2017). Its main function is to manage the operation of the daytime running lights (DRL) and the LED turn signals (indicators) on the right side of the vehicle.

What is it for and why should you replace it?

This module is an electronic control unit that controls the power, brightness, and sequences of the LED lights. It is an essential component for the proper functioning of the vehicle's front lighting.

The reasons why it needs to be replaced are almost always related to a malfunction . If the daytime running lights or the right headlight turn signal stop working or flash abnormally, the problem is most likely with this module. Replacing it with an original or equivalent part is the only solution to restore proper functioning.

Vehicles with a faulty module may often display error messages on the dashboard such as "Vehicle lights: fault" or "Right side light/daytime running light defective." Replacement is a plug-and-play process, meaning no additional vehicle programming or coding is required.
