Why are the low beams on the Audi A4L different on both sides?
2 Answers
Audi A4L low beams are different on both sides because China is a right-hand traffic country. Therefore, the left low beam has a slightly shorter illumination distance than the right low beam to minimize glare for oncoming drivers, ensuring safety. The Audi A4L is a mid-size car under FAW-Volkswagen Audi, with dimensions of 4858mm in length, 1847mm in width, and 1439mm in height, and a wheelbase of 2908mm. In terms of power, the Audi A4L is equipped with a turbocharged engine that delivers a maximum horsepower of 150 hp, a maximum torque of 270 Nm, and a maximum power output of 110 kW.
The uneven brightness of the low beams on both sides of my Audi A4L is most commonly caused by unbalanced bulb aging, such as one side's filament burning out or reaching the end of its lifespan, resulting in uneven illumination. Electrical issues could also be at play, such as a blown fuse or poor relay contact, leading to unstable current—especially if Audi's automatic leveling system malfunctions, which can more easily cause this kind of light imbalance. Dirty or damaged lenses can also affect the reflection efficiency of the light, making one side appear dimmer. It's recommended to visit a professional shop as soon as possible to test the voltage and bulb condition. Don't delay until nighttime driving becomes hazardous, as this discrepancy can also easily cause oncoming vehicles to misjudge the situation.
