What are the reasons for the Audi A4's start-stop system not working?
1 Answers
Audi A4's automatic start-stop system may not work due to the engine not reaching normal operating temperature; automatic air conditioning not reaching the preset temperature; insufficient battery power, turning the steering wheel after stopping; emergency braking or reversing; cold weather with an outside temperature below 5 degrees Celsius. Principle of Automatic Start-Stop: Automatic start-stop refers to a system that automatically shuts off the engine when the car comes to a temporary stop during driving. When it's time to move forward again, the system automatically restarts the engine. Simply put, it's a system that can control engine shutdown and ignition automatically, abbreviated as STT. How to Use Automatic Start-Stop: While driving, simply press the brake pedal, and the engine will automatically shut off about 2 seconds after the car comes to a complete stop. Keeping the brake pedal pressed will maintain the engine in the off mode. As soon as you release the brake or turn the steering wheel, the engine will automatically restart, allowing you to press the accelerator and start moving immediately, all while remaining in D (Drive) mode. If the car is driving on a steep slope, it's best not to activate the automatic start-stop. Although the start-stop time is brief, using it on a slope can lead to insufficient brake assistance.
