Where is the headlight control module located in the Volkswagen Passat?

The headlight control module in the Volkswagen Passat is located below the left air vent on the steering wheel side. Introduction to car headlights: Car headlights, also known as automotive front lights or LED daytime running lights, serve as the 'eyes' of a vehicle. They not only contribute to the owner's external image but are also crucial for safe driving at night or in adverse weather conditions. History of car headlights: The first car headlight was essentially a household portable lamp. In 1887, a driver lost in a dark wilderness was guided home by a farmer using such a lamp. In 1898, the Columbia electric car introduced electricity for both front and rear lights, marking the birth of automotive lighting.
I remember helping a friend with his old Passat. The headlight control module is located under the steering wheel on the driver's side. If you open the door and crouch down to look, you'll find the fuse box hidden behind the knee bolster trim panel, where the module is usually mounted. When removing it, you must first disconnect the battery and carefully pry open the clips with a plastic trim tool—the wiring harness inside is packed tightly. In newer Passat models, it might have been relocated near the fuse box on the left side of the engine bay. Last time at the dealership, I saw a technician working on it and noticed the module had the VW logo and part number. If you're doing it yourself, it's best to take photos to document the wiring sequence—incorrect connections can fry the ECU. If the headlights flicker without reason, it's likely due to water intrusion or aged circuits in the module, and a replacement should be installed promptly.
