Why does my Audi turn off on its own?
The Audi start/stop technology automatically shuts off the car’s engine when the vehicle is stopped (at a stop sign or drive-through, for example), and then starts it back up before the vehicle moves again in order to conserve energy and lower CO2 emissions. In order to start the system repeatedly while it is in use, a heavy-duty starter and a deep-cycle battery are used.
The engine automatically turns off when the vehicle comes to a halt, the driver selects neutral, and they let go of the clutch. The engine immediately starts when the clutch is depressed once more, allowing the vehicle to be driven away. The start/stop feature only functions when the hood and driver’s door are shut, the driver is buckled up, the vehicle was traveling at a speed more than 2.5 mph when it stopped, and no trailer is being pulled. If the engine temperature is too low, the outside temperature is too high or too low, the air conditioner is on, the windshield is being defrosted, the power consumption is too high, or the battery is low, the engine may not automatically shut off (or turn back on). When the car is started, the system is automatically enabled, but it may also be turned off by pressing a button.
