The “coming home” and “leaving home” feature, controlled by your car’s computer system, automatically turns on your headlights as you approach or leave your vehicle. While a convenient feature, especially for safety and visibility in low-light conditions, adjusting it often requires a diagnostic tool like VCDS (Vag-Com Diagnostic System). This article explores VCDS coming/leaving home modifications, providing a guide for car owners, repair shops, and automotive technicians.

What is VCDS and How Does It Work with Coming/Leaving Home Lights?

VCDS is a powerful software that allows you to access and modify the control modules in your Volkswagen Group vehicle (VW, Audi, Seat, Skoda). This includes settings for your coming/leaving home lights. By connecting a VCDS interface cable to your car’s OBD-II port and your computer, you can adjust various parameters like light duration, intensity, and even activate or deactivate the feature altogether.

Common VCDS Coming/Leaving Home Light Adjustments

VCDS offers a range of adjustments for your coming/leaving home lights:

• Duration: You can customize how long the lights stay on, ranging from a few seconds to over a minute.
• Light Selection: Choose which lights are activated – headlights, fog lights, interior lights, or a combination.
• Activation Conditions: Determine when the feature engages, such as unlocking the car, opening a door, or using the remote control.
• Daytime Running Lights (DRLs): Integrate the coming/leaving home function with your DRLs for enhanced visibility.

Step-by-Step Guide to Adjusting Coming/Leaving Home Lights with VCDS

Before you begin, ensure you have the necessary tools:

• A laptop with VCDS software installed.
