The coming home/leaving home lights feature automatically turns on the headlights when you unlock or lock the car, providing additional visibility in dark conditions. This feature is often disabled from the factory but can be enabled using VCDS.

To enable the coming home/leaving home lights, you typically need to access the central electronics module (module 09) and modify the coding and adaptation settings. The exact procedure can vary depending on the car’s equipment level.

Example:

1. Connect VCDS to your car and select the central electronics module (09).
2. Go to coding and enable the coming home/leaving home lights function.
3. Go to adaptation settings and adjust the duration of the lights.
4. Save the changes and test the feature.

After enabling this feature, the headlights should automatically turn on when you unlock the car (leaving home) and when you turn off the ignition and remove the key (coming home).

2.4 Activating Cruise Control

If your MK4 VW didn’t come with cruise control from the factory, it’s often possible to retrofit it and activate it using VCDS. This typically involves installing a cruise control stalk and wiring harness, then using VCDS to enable the function in the ECU.

To activate cruise control, you typically need to access the engine control unit (ECU) and modify the coding. The specific steps can vary depending on the ECU type and the cruise control system installed.

Example:

1. Install the cruise control stalk and wiring harness.
2. Connect VCDS to your car and select the engine control module (01).
3. Go to coding and enable the cruise control function.
4. Save the changes and test the cruise control system.

After enabling cruise control, you should be able to set and maintain a constant speed using the cruise control stalk.

2.5 Disabling Seat Belt Warning Chime

Many drivers find the seat belt warning chime annoying, especially when driving short distances or in situations where wearing a seat belt is not required. Using VCDS, it’s possible to disable the seat belt warning chime.

To disable the seat belt warning chime, you typically need to access the instrument cluster module (module 17) and modify the coding. The exact procedure can vary depending on the instrument cluster type.

Example:

1. Connect VCDS to your car and select the instrument cluster module (17).
2. Go to coding and disable the seat belt warning chime.
