What Causes Porsche Start-Stop Function Malfunction?
1 Answers
Here are the reasons for Porsche start-stop function malfunction: 1. Accidental system deactivation: Vehicles equipped with automatic start-stop typically have the system enabled by default. If it suddenly stops working, it might be due to accidentally pressing the auto start-stop button, which deactivates the system. Check if the system has been turned off. 2. Start-stop function not activated: For manual transmission vehicles, the conditions for enabling auto start-stop are more complex. The system only activates when it detects three actions: "shifting to neutral, engaging the handbrake, and releasing the clutch" when parked. 3. Different setup methods: Auto start-stop systems vary across different brands and models. Taking the new Passat's system as an example, certain conditions must be met: the seatbelt must be fastened, the front left door must be closed, and the engine must be running. Therefore, check the user manual for any specific precautions. 4. Requirements not met: The function will not activate under the following circumstances: engine not reaching normal operating temperature, automatic AC not reaching preset temperature, insufficient battery charge, steering wheel turned after stopping, emergency braking, or reversing. You can refer to the above points for troubleshooting.
