Audi's 'Check Oil Level' warning is an alert indicating abnormal engine oil level. It advises the owner to check the oil level via the system or dipstick to determine whether to add or drain oil. Procedure to reset Audi's oil check reminder: In the infotainment system, select: Menu - Car - Left control button - Service and Inspection - Service Interval - Reset Oil, then change the interval. How to interpret oil warning signals: A yellow oil warning light indicates the computer detects low oil level, which could mean oil shortage or a faulty oil level sensor. A red warning light means insufficient oil pressure. First, check if the oil pressure sensor is damaged. If not, inspect whether the oil pump intake is blocked, which may require removing the oil pan for examination.
