How often does the Audi A4L require a major maintenance service?
3 Answers
The Audi A4L requires a major maintenance service approximately every 40,000 kilometers or every two years. The major maintenance service includes: 1. Inspection of the engine, chassis, and transmission; 2. Replacement of the oil filter, cabin air filter, and air filter; 3. Cleaning of the engine and throttle body; 4. Inspection of the wheel hubs and braking system; 5. Replacement of spark plugs and engine belts; 6. Cleaning of the air conditioning system; 7. Inspection of the battery. Taking the 2020 Audi A4L as an example, it belongs to the mid-size car category, with body dimensions of: length 4858mm, width 1847mm, height 1439mm, a wheelbase of 2908mm, and a fuel tank capacity of 56 liters.
When it comes to the major maintenance cycle of the Audi A4L, I referred to the official manual and repair experience. It is generally recommended to perform a major service every two years or every 40,000 kilometers, whichever comes first. At this time, the basic maintenance should be upgraded, such as changing the engine oil and oil filter, and the air filter, which are essential. It's also necessary to check the condition of the brake fluid and coolant. Special attention should be paid to the transmission fluid; some drivers with aggressive driving habits might need to replace it earlier. Tire rotation and brake pad wear inspection should not be overlooked either. My experience is that regular maintenance can prevent minor issues from turning into major repairs. After all, Audi cars have relatively precise components, and with proper maintenance, they can run smoothly for ten years without any problems.
My A4L has been running for over six years, and I maintain it on a schedule of major service every 40,000 kilometers. The specific approach involves replacing all fluids, including brake fluid and transmission oil, and the spark plugs usually need replacement at this point as well. Checking the chassis and suspension is particularly important because uneven urban roads can easily cause parts to loosen. The air filter and cabin air filter directly affect the air quality inside the car, so I replace them every time. Actually, the biggest expense in major maintenance is the labor cost, while the cost of materials is secondary. If I drive long-term in dusty areas, I’ll perform maintenance at 35,000 kilometers instead, since engine carbon buildup can lead to much more expensive repairs later.
