What does the Audi A4 low engine oil fault display indicate?
2 Answers
Audi A4 low engine oil fault display occurs because the maintenance light was not reset after adding engine oil. Performing the maintenance light reset will stop the low engine oil fault from being displayed. Using a computer for maintenance reset: Use an automotive computer diagnostic tool to reset the maintenance light. At a 4S dealership, connect to a diagnostic computer or directly set it in the vehicle. After maintenance, manually cancel the prompt to reset and enter the next cycle. Manual reset: Manually reset the maintenance light. First, insert the key into the ignition switch and wait a few seconds. Press and hold the button on the lower right of the instrument panel, turn the key to the 'on' position (do not start the engine), wait ten seconds, release, and then press the button on the left to clear the indicator.
I've driven an Audi A4 for over ten years since I was young, and the warning for low engine oil is particularly noticeable. The yellow oil can light on the dashboard will illuminate, and sometimes the central screen will pop up a message in Chinese or English indicating low oil level. The most common cause is an oil leak, such as a loose oil pan screw or an aging seal causing the oil to slowly seep out. It could also be due to prolonged engine use leading to internal wear and increased oil consumption. I remember one time when I neglected to check in time, the car started making strange noises while driving, which startled me, so I immediately stopped to add oil, thus avoiding a major repair. I recommend checking the dipstick level every time you refuel and topping up with the manufacturer-recommended 5W-30 oil if it’s low. It’s also best to inspect the underside of the car monthly for any oil stains to save a lot of trouble.
