The warranty period is three years or 100,000 kilometers, whichever comes first. The schedule is every 5,000 kilometers. Below are the details: 1. First Maintenance Free: The first maintenance is free, and the second maintenance waives the labor fee. The maintenance interval is every 5,000 kilometers. Under normal conditions, the engine timing chain system, electric power steering system, MT and CVT transmission fluids are maintenance-free for life. 2. Replacement Parts: Replace the cabin air filter every 20,000 kilometers, the engine air filter and brake fluid every 40,000 kilometers. The fuel filter and automatic transmission fluid should be replaced every 80,000 kilometers, while the spark plugs need replacement every 100,000 kilometers.

















I've been driving a C260L for three years, and maintenance really depends on daily usage. The manufacturer recommends a minor service every 10,000 kilometers or once a year, but with my daily city commuting plus school runs, I usually need a check-up around 7,000-8,000 kilometers. Remember, the first service was done at 8,000 kilometers, including an oil and filter change plus a full vehicle inspection; at 20,000 kilometers, I replaced the cabin air filter and brake fluid. The key is not to just focus on mileage—pay attention to tire pressure monitoring alerts and maintenance reminders popping up on the central display. Last week, the 40,000-kilometer major service cost over 2,000 yuan, involving transmission fluid and spark plug replacements. The mechanic mentioned that with so many sensors in this car, delayed maintenance can easily trigger fault codes.

I mainly drive the C260L on highways for business trips, so I'm more cautious about the intervals. The official Mercedes-Benz maintenance cycle is once a year or every 10,000 kilometers, but since I drive over 2,000 kilometers per month on long-distance trips with faster oil consumption, I now service it every nine months. Each basic maintenance service includes similar items: oil and oil filter change, brake disc wear inspection, and battery health check. I pay special attention to the air filter, as I frequently drive to construction sites, and it's usually heavily clogged with dust during each service. Once, when I delayed maintenance by two months, the engine noise became noticeably louder. I recommend checking the ASSYST PLUS system prompts in the vehicle, as it dynamically adjusts the maintenance schedule based on driving habits.

Following the schedule in the manual is always the right approach. The Mercedes-Benz C260L manual specifies maintenance every 10,000 kilometers or twelve months. I picked up the car last April and it's now time for the second service. The first service was done at 9,000 kilometers, which included a routine oil change and inspection. At the 20,000-kilometer mark, I had the coolant topped up. From my experience, it's best not to fixate solely on the mileage. Pay attention to whether the yellow wrench icon appears on the dashboard when starting the vehicle. My service advisor mentioned that if you frequently drive short distances in the city, it's advisable to service the car every ten months to prevent oil emulsification. Nowadays, you can schedule door-to-door car pickup for maintenance via the app, which saves a lot of time.

As an owner of the older C260L model, I've learned my lesson about intervals. Initially following the manual's 10,000-km service schedule, my transmission developed abnormal noises by 50,000 km. The mechanic advised oil changes every 8,000 km for this engine generation, especially with frequent auto start-stop usage. I now stick to basic maintenance every 10 months or 7,500 km, always checking antifreeze freezing points before winter. Key reminder: monitor brake pad thickness - OEM Mercedes pads typically wear out by 40,000 km. Last service revealed slight coolant pipe seepage, fortunately caught in time with a gasket replacement.

I've been driving the C260L for five years and have figured out some tricks regarding the schedule. The official recommendation is maintenance every 10,000 kilometers, but using AMG engine oil can extend it to 12,000 kilometers. The key factors to monitor are: engine oil life (checkable via the central console), frequency of auto start-stop usage, and long-term average speed. Based on my maintenance records, I suggest maintenance every nine months for city commuting, while highway-heavy usage can stretch to a full year. Pay special attention to changing the brake fluid every three years and the cabin air filter every two years. Once I delayed maintenance until 13,000 kilometers, and the engine warning light came on. Now I book the dealership service two weeks in advance and get a 20% discount on labor costs.
