7500 kilometers to 10000 kilometers is acceptable, but be sure to use TDI-specific engine oil. Some 4S shop maintenance personnel have special requirements for this diesel engine. Car maintenance precautions: Pay attention to promptly remove corrosive substances such as bird droppings. Try to avoid driving in areas with strong corrosiveness, such as coastal areas, roads with de-icing agents, newly paved asphalt roads, etc. Introduction: "Vehicles" refer to motor vehicles and non-motor vehicles. "Motor vehicles" refer to wheeled vehicles driven or towed by power devices that are used for carrying passengers, transporting goods, or performing special engineering operations on roads.
My A6L diesel version has been running for several years, and I usually change the engine oil every 12,000 to 15,000 kilometers. As experienced drivers know, diesel engines tend to accumulate more sludge, so frequent oil changes are necessary to maintain smooth power delivery. I often check the dipstick myself, and if the oil color turns black, I change it ahead of schedule. If there's a lot of city traffic congestion, doing it every 10,000 kilometers is safer and can save on repair costs while protecting the engine.
For a longer lifespan of your beloved car, don't slack off on oil changes. Audi diesel vehicles recommend an oil change around 15,000 kilometers, but I always take mine to the shop for a check at around 10,000 kilometers—unstable oil pressure can easily damage the engine. For those who frequently drive long distances at high speeds, you can stretch it a bit longer; for more short trips, shorten the interval. It's more reliable to decide based on the oil condition rather than waiting for the warning light to come on.
