Another is the 'Follow Me Home' light feature, where the headlights stay on for about 30 seconds after locking the car, illuminating your path home and avoiding fumbling in the dark to open the door. There's also the lock confirmation beep activated via a diagnostic tool, which confirms the locking status and enhances peace of mind. The dashboard display brightness can also be adjusted to adapt to different lighting conditions, making daily use more convenient. Although setting these up yourself requires a VCDS tool, it's safer to have a mechanic do it to avoid messing up the wiring. Regular of circuit fuses is also crucial.
