What is the maintenance cost of the Mercedes Benz C 300?

Mercedes Benz performs two types of maintenance on passenger cars, which are called service A and Service B. Service A is the first service of the vehicle and is usually performed at 15000km or 1 year. Service B is every second service of the vehicle, it is a major service as the vehicle mileage can be 30,000 to 45,000 km.

 Service A of Mercedes Benz C 300 can cost around 500 $, the cost can increase if there are additional jobs identified during the service. The customer can also select a variety of interior and exterior treatments that can be performed after the service is over. 

The cost of service B can be between 600 $ to 800 $, as service B is a major service. Certain parts like the spark plugs, cabin filters & in some cases air filters must be replaced so the vehicle can last long and give the same amount of comfort and performance to the customer.

Mercedes Benz C 300 uses a 9 G Tronic 725 transmission. The transmission is not sealed for life unlike some of its competitors. Every 4 years or 60,000 km the transmission fluid and oil filters must be replaced. The reason for replacing the transmission fluid is to maintain the reliability of the gearbox and avoid customer complaints like bad shift quality. 

Mercedes Benz service is not just limited to the oil change, Mercedes Benz cars are the most advanced cars on the roads today and there are many critical components present on the vehicle. All the functions are checked according to the service check sheet of the C 300. The fault memory is also scanned using the Xentry diagnosis tool. A vehicle health card is filled by a technician after assessing the condition of brake pads, brake disc and main battery and it is presented to the customer at the time of delivery of the vehicle. 

Which engine and engine oil is used in the Mercedes C 300?

The Mercedes Benz C 300 comes with a 2-litre inline turbocharged petrol engine. New models also have Mercedes Benz camtronic technology which changes cam profile and can shift to a larger valve opening to produce more power. 

The M264 used in C300 produces 225kW 400NM torque. The M274  produced 200kW and 370NM of torque, it is being replaced by the M264 in Newer modes. Both the engines have liquid-cooled intercoolers but the M274 does not have Camtronic in some markets. 

The M264 also has NANOSLIDE coating on the cylinder walls. This is an extremely thin coating applied to the inner surface of the cylinder to reduce friction between the piston. Twin-wire arc spraying (TWAS) is used to spray an extremely thin coat of iron-carbon alloy on the cylinder walls.  The friction between the piston and piston rings is reduced by almost 50 percent.

The engine oil used at authorised dealerships is usually 0W 40 where W stands for Winter. 0W 40 engine oil can flow like0 weight oil in cold conditions but still offer the protection of 40 w oil when the engine reaches its full operating temperature. 5 W 40 is also suitable for vehicles that do not operate in extremely cold conditions.

Mercedes Benz has standard 0 W 40 fully synthetic engine oil and a high-performance version Mercedes Benz AMG 0w 40 which can be used in the C300 if the customer decides to opt for it.

Like any other German car manufacturer, Mercedes Benz tests and publishes specified oil grades in MB sheet numbers. The MB sheet numbers start from MB226.5 and go till MB 229.7, depending on the engine in the vehicle the correct MB sheet number oil is used.

What are the additional jobs in the C300?

The C300 service checksheet included a visual inspection of the vehicle’s underbody. Suspension components like lower control arms, thrust arms, ball joints and shock absorbers are checked. Any cuts or leaks are identified which can compromise the operation of the vehicle. Following are the possible additional jobs.

  • Suspension components-

Suspension components are subjected to constant stress and they are more exposed to the elements. Despite the superior quality of Mercedes Benz parts, certain components like shock absorbers, and ball joints can leak due to bad road conditions. 

If the vehicle is under warranty, any manufacturing defects are covered and the affected parts are replaced free of cost but if the vehicle is outside of warranty, the cost of suspension components can add up to the overall service cost.

  • Engine oil leaks

The M264 has a complex design and many oil seals that can leak engine oil. Engine oil leaks are identified before performing an oil change. The quality of engine oil drained is also checked, if it is less than the specified quantity further checks are performed to ensure there is no excessive engine oil consumption. 

Engine oil leaks can be expensive to rectify, oil leaks from crankshaft rear oil seal need complete removal of engine and gearbox from the vehicle and total repair cost can be up to 600 $

  • Brake pads and brake discs

Brake pads and brake discs are not covered under warranty as they are classified as worn components. Usually, Mercedes Benz brake pads and discs can last for 30000 km but if the vehicle is used in the city and under a constant braking zone, then the brake pads are replaced during the service.

There is a brake wear sensor that activates the brake service light in the instrument cluster to warn the driver. The wear limit of brake pads is 2-3 mm and the thickness of the brake disc is measured by a vernier calliper, if the thickness is below the specified limit the brake discs are also replaced.

The cost of front and rear brake pads can be 500 $ and the brake disc is up to 1000 $.

  • Main Battery- 

The main battery is checked by the Midtronics battery tester, under a standard warranty the main battery is replaced if there are any malfunctions. However, it is not covered in the fourth year or any extended warranty. The cost of the main battery is approximately 300$.

Mercedes Benz uses AGM (absorbent gel matt)batteries and customers can also install lithium-ion batteries which can last longer than the AGM batteries. Using non-genuine or flooded batteries is not recommended in Mercedes Benz cars.
