[SanSamantha]

Here are the steps to reset the oil change reminder on the Audi A3 display: 1. In the infotainment system, select the button (Menu), then the left-side control button for the car. 2. Choose Maintenance and Inspection, then Service Interval, and reset the oil change interval to clear the reminder. Below are the functions of engine oil in the Audi A3: 1. Reduces wear: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. To prevent excessive wear on parts, it is necessary to establish an oil film of sufficient thickness between the sliding surfaces to separate them, thereby reducing wear and extending mechanical life. 2. Cools the engine: The engine oil helps the radiator cool the engine by dissipating heat away from the engine. 3. Seals and prevents leaks: The engine oil forms a seal between the piston rings and the piston, reducing gas leakage and the entry of contaminants.
