Many VW Golf 6 owners, especially those with US-spec models, find the parking light (Standlicht/Parklicht) settings confusing. This article clarifies the functionality of these features, particularly when using VCDS (Vag-Com Diagnostic System) for customization. We’ll explore common questions surrounding “Standlicht” and “Parklicht” and how they interact with the vehicle’s battery energy management (BEM) system.
Decoding Standlicht and Parklicht
In German, “Standlicht” translates to “standing light,” essentially referring to position lights that indicate the vehicle’s presence when parked. These lights are typically activated when the ignition is on or the engine is running (Terminal 15 on). “Parklicht,” on the other hand, specifically means parking light and serves the same purpose – to mark the car’s position when parked. The key difference lies in activation: Parklicht is enabled when the ignition is off (Terminal 15 off) either on both sides using the rotary light switch or on a single side using the turn signal stalk.
VCDS and Parking Light Configuration
VCDS allows access to various vehicle control modules, including those managing lighting functions. Within these modules, adaptation channels control specific parameters, including the duration and behavior of the parking lights. Commonly adjusted channels relating to “Standlicht” include:
- After-run for park light – Conditions for ending the position light after-run: This setting determines how the position lights turn off. Options often include time-based shutoff or control via the BEM.
- After-run for park light – Conditions for position light limitation: Similar to the above, this dictates how the duration of the position lights is managed.
- After-run for park light – Factor for availability timer: This factor, often multiplied by 5 minutes, contributes to calculating the maximum runtime for the parking light function.
- After-run for park light – Position light after-run time: This setting specifies the duration (in minutes) for which the position lights remain on after the engine is turned off.
- After-run for park light – Position light availability: Although labeled with “s” for seconds in some VCDS versions, this parameter often acts as a factor working in conjunction with the “Factor for availability timer.”
Battery Energy Management (BEM) Interaction
Modern VW vehicles employ BEM to optimize battery usage and prevent discharge. This system can override user-defined time limits for parking lights to conserve battery power. If BEM detects a low battery level, it may deactivate the parking lights, even if they are programmed to remain on for a specific duration. This prioritizes essential vehicle functions over extended parking light operation.
Understanding Default Values
Some VCDS channels may display default values (e.g., 255 minutes for position light after-run time) that are not actually utilized if BEM controls the parking lights. This apparent discrepancy arises because the time-based limit is disregarded when BEM is active.
Conclusion
While seemingly complex, understanding the nuances of VCDS and the interplay between “Standlicht,” “Parklicht,” and BEM provides greater control over your VW Golf 6’s lighting configuration. By carefully adjusting the relevant adaptation channels, you can customize the behavior of your parking lights while ensuring compatibility with the vehicle’s battery management system. Remember to consult reputable sources and exercise caution when modifying vehicle settings with VCDS.
