The rear reading light of Golf 8 cannot be turned off due to a malfunction of the interior light switch. The following is a detailed introduction to Golf 8: 1. Body dimensions: The length, width, and height are 4284mm/1789mm and 1456mm respectively, with a wheelbase of 2636mm. 2. Powertrain: Five hybrid systems are offered, including three eTSI 48V hybrid systems and two GTE plug-in hybrid systems. The 48V mild hybrid models have maximum power outputs of 110 horsepower/130 horsepower and 150 horsepower, while the GTE plug-in hybrid models have maximum power outputs of 204 horsepower and 245 horsepower. The GTE plug-in hybrid models are equipped with a 13kWh lithium-ion battery, providing a pure electric range of 60km.

Yesterday, I took my family out in a Golf 8 and noticed that the rear reading light wouldn't turn off, which was quite annoying. The issue could be due to a stuck switch button or the light being triggered by a door that wasn't fully closed. The Golf 8 is a new model with more electronic controls, so if the central console settings are messed up, the lights might act up. I tried pressing the switch next to the light repeatedly—sometimes it doesn't pop back up, leaving the light permanently on. Additionally, loose wiring or sensor false alarms are common issues, like the seat pressure triggering the light. I recommend checking if all doors are properly closed and gently tapping the light switch to see if it resets. If that doesn’t work, it's best to visit a 4S shop to prevent any circuit issues from affecting the battery life, as driving at night with distracting lights isn’t safe either.

I've dealt with similar issues before. The problem of the Golf 8 rear lights not turning off is often related to the electrical system. It might be caused by poor internal contact in the switch preventing circuit interruption. A simple test method is to repeatedly press the switch and listen for a clicking sound. It could also be a control module failure - these small electronic components in cars frequently cause issues. Don't rush to remove the panels; first check the fuse box in case of any blown fuses. Additionally, if the door position sensor is inaccurate, the system may think the door is open and keep the lights on. I personally use a multimeter to test circuit continuity for initial diagnosis, but if you're not familiar with electrical systems, it's better to consult a professional technician. The Golf 8's body control module is complex - don't risk messing with it yourself. Remember to save your settings to prevent recurrence of the issue.

I remember when the rear light in my Golf 8 wouldn't turn off, I figured it was due to a worn-out switch getting stuck, with the spring too fatigued to bounce back. The issue also included oxidized wiring connectors causing poor contact, especially prone during humid seasons. Later, I manually pressed the switch a few times, and it obediently turned off. Don't underestimate this power drain—leaving it on all night could drain the battery, making it troublesome if the car won't start in the morning. It's best to address it promptly to avoid unnecessary expenses.
