How to disable fog lights from turning on when unlocking a 2013 Audi A4L?

Fog lights can only be operated when the headlights or parking lights are turned on simultaneously. The Audi A4L fog lights consist of front and rear fog lights. Turning on the headlights is a prerequisite for activating the fog lights. Here is the position of the automatic headlights. It is recommended to use fog lights in conjunction with the headlights. Of course, you can also turn on the parking lights and use the fog lights at the same time. The effect is even better when the headlights and fog lights are turned on together. Fog lights are mainly used in foggy weather.

I've researched the lighting settings on the 2013 A4L, and the issue with fog lights turning on when unlocking is easy to fix. First, get in the car and turn the key to the ACC position without starting the engine – just make sure the dashboard lights up. Then, navigate to the vehicle settings menu on the center console screen and look for the lighting or exterior lighting options. There's a 'Welcome Lights' feature that usually includes automatic light activation when unlocking. Enter this menu and disable the fog light option, then save the settings. I've modified this before so only the headlights turn on or nothing at all when unlocking, which saves battery and doesn't affect nighttime visibility. If you can't find the menu, check the owner's manual for the relevant section. The whole process takes about 5 minutes and you can do it yourself, but make sure to test whether it works properly to avoid any issues on the road.

As a long-time owner of the 2013 A4L, I've also experienced the annoying issue where the fog lights keep turning on when unlocking. The solution is to sit in the car, turn on the power without starting the engine, then access the settings menu via the steering wheel buttons or MMI system. Select the lighting configuration, find the unlock lighting section, and deactivate the fog lights. I successfully made this change, and now unlocking is quiet and worry-free, especially saving battery in underground garages. It's recommended to check for system updates to avoid bugs in older versions. After the modification, the car feels smarter without affecting the safety of the main headlights. If you get stuck, you can check the exact button locations on forums – it's not difficult.

Setting this up is super easy! Just get in the car, turn on the power without starting the engine, then go to the vehicle settings in the central control menu and find the lighting adjustment unlock option. Deactivate the fog lights and save the changes. After I made this adjustment, only the headlights illuminate during unlock, which is much better and more eco-friendly without any hassle. The whole process takes just a minute or two, and it's fun to DIY without needing any tools. If the system responds slowly, try restarting the power—it'll definitely work.

I used to frequently encounter the issue of unlocking fog lights draining the battery. My suggestion is to enter the system settings to adjust the lighting without starting the engine after getting in the car. After disabling the fog lights in the welcome light option and saving, it will automatically cancel. After making this change, I found peace of mind as safety is the top priority—don't completely turn off the lights, leave the headlights on as a warning. Manual operation is easy to get used to, and having the manual for reference makes it even more reassuring.
