Where is the horn relay located in the Audi A4L?
2 Answers
The horn relay of the Audi A4L is located in the fuse box on the left side of the engine compartment. Generally, car horns are positioned inside the front wheel bumper, but some models have them installed within the grille. Taking the 2020 Audi A4L as an example, it is a mid-size sedan with body dimensions of: length 4858mm, width 1847mm, height 1439mm, wheelbase 2908mm, and a curb weight of 1610kg. The 2020 Audi A4L features front and rear five-link independent suspensions, equipped with a 2.0T turbocharged engine delivering 150PS maximum horsepower, 270Nm peak torque, and 110kW maximum power, paired with a 7-speed dual-clutch transmission.
Hey, I often tinker with Audi cars and am quite familiar with the A4L. The horn relay is usually located in the fuse box in the engine compartment, specifically under the hood near the windshield or the battery in a black plastic box. Open the box cover, and you'll find a diagram label clearly indicating the position of the 'horn relay,' often marked with a symbol or code like 'K2.' If your car is an older model, say pre-2010, it's fixed there; newer models might have it slightly shifted, but generally in the same area. If it's not there, check the interior fuse panel—near the steering wheel or inside the glove compartment—just remove the small panel to find it. Always disconnect the negative battery terminal before working to prevent electrical sparks from injuring your hands. Relays can fail due to aging or voltage instability, causing the horn to stop working, so regular checks can prevent roadside troubles. I recommend consulting the manual or online diagrams for your specific model year to be more precise and save effort.
