Audi Q3's yellow oil 'min' warning light indicates that the vehicle's system has detected insufficient engine oil level. You should stop the car and check if there is an oil shortage. If no obvious external leakage is found, you can add oil, typically about one liter. After adding, check the oil level on the display. Once it returns to normal, you can continue driving. Methods to check the oil level: Using the electronic oil dipstick: Many cars have an oil level check function in the central control screen. Checking via the radio or MINI screen: Park the car on a level surface, press the CAR button, select 'Oillevel' (oil level), then let the car reach operating temperature and idle for a while before turning off the engine. Wait 2 seconds to see the oil level. If the oil column is near the 'min' mark, it means you need to add oil. Can you continue driving when the engine oil is at the lower limit? Generally, engines have about one liter of capacity between the lower and upper limits of the oil dipstick. Even if the oil dipstick shows the lower limit, it only means the engine oil has reached the minimum allowable level, not that there is no oil. In this case, the lubrication for the engine is still sufficient, and the car can be used normally. However, besides lubrication, oil also has cooling and heat dissipation functions, especially in turbocharged engines, which have dedicated oil nozzles to cool the pistons. Insufficient oil can weaken the engine's cooling function. If you drive aggressively under these conditions, the engine may become overloaded, leading to overheating. Therefore, aggressive driving should be avoided, and unnecessary uphill driving should also be minimized to prevent insufficient engine lubrication under extreme conditions, which could damage the engine.
