Small service for Mercedes C klasa C63 AMG S E Performance PHEV (680)

Small service for Mercedes C klasa C63 AMG S E Performance PHEV (680) is the foundation of a healthy engine and the long lifespan of your vehicle. Timely maintenance is far more than a formality — it is a deliberate investment that pays back over the years through lower fuel consumption, lower repair costs and safer driving for you and other road users. At Royal Auto Service Belgrade we perform the small service for Mercedes C klasa C63 AMG S E Performance PHEV (680) precisely, to factory standards, using only materials and parts that guarantee top engine performance. The recommended interval is every 10,000 to 15,000 km, or once a year — whichever comes first. 

The small service for Mercedes C klasa C63 AMG S E Performance PHEV (680) includes: 

• Engine oil change: we install only original synthetic oils of premium quality that have been tested for your engine and ensure optimal lubrication, reduced friction and protection against wear in every operating condition. 
• Filter set change: engine oil filter, air filter, fuel filter and cabin filter (with activated carbon for purifying the cabin air) — all in a single service visit. 
• Diagnostic check: reading stored fault codes from every electronic controller using factory-grade diagnostic equipment, plus resetting the service interval in the vehicle computer. 
• Inspection of vital points: detailed check of the brake system (pads, discs, brake fluid), coolant and antifreeze level, battery and alternator condition, lights (headlights, brake lights, indicators), tires and steering system. 

Detailed work plan

Phase 1: deep engine flush and decarbonization (preparation)

• Old oil extraction: Complete pumping out of worn engine lubricant from all engine channels, including parts not accessible by gravity drainage.

• Triple internal engine flush: Pouring special mineral oil with a high concentration of detergent and dispersant additives. The engine runs in three 15-minute cycles — during this time the additives thoroughly clean oil channels and main lines from metal shavings and accumulated sludge.

• System drain: Releasing the dirty mineral oil from the engine after the internal cleaning process is complete.

• Engine decarbonization: Professional 45-minute treatment that removes carbon deposits from the combustion chamber, valves and exhaust system — particularly important for diesel engines and modern direct-injection petrol engines.

• Intake system cleaning: Preventive treatment of MAP and MAF sensors against soot, plus cleaning of the intake manifolds and EGR valve with dedicated intake cleaner products that extend sensor life and preserve factory engine performance.

Phase 2: filtration and modern technology (filling the system)

• Oil filter replacement: Installing a new original or OE-equivalent filter that meets every factory specification (Mahle, Mann, Bosch).

• Filling the engine with quality synthetic oil: Pouring the factory-recommended motor oil of class ACEA C2/C3 or A5/B5, with nano-additives that provide additional protection of vital components and reduce consumption.

• Level and quality check: Measuring the exact level after a short engine run and visual inspection of the oil's color and consistency to confirm there is no water, antifreeze or fuel in the system.

Phase 3: complete check of the remaining filters and fluids

• Air filter: Condition check, cleaning or replacement if dirtier than the factory limit.

• Fuel filter: Replacement based on mileage and fuel type (diesel or petrol) — for diesel engines we always check the water separator as well.

• Cabin filter: Replacement of the filter with activated carbon that protects passengers from pollen, dust and exhaust fumes from outside traffic.

• Antifreeze/coolant: Concentration and freezing point check, top-up or full replacement if expired.

• Brake fluid: Moisture content test — brake fluid absorbs water and loses efficiency, so it is checked and replaced every 2 years.

Phase 4: complete electronic diagnostics

• Reading faults from every controller: engine ECU, transmission, ABS, ESP, climate, airbag, immobilizer, BSI/CAN bus — all with factory-grade diagnostic tooling.

• Real-time sensor parameter check: lambda sensors, MAP/MAF sensor, engine temperature, fuel pressure, RPM, catalyst load parameters.

• Clearing historical errors and resetting service indicators: So that any new errors during the next operation period can be tracked.

Phase 5: visual inspection of chassis and steering

• Inspection of shock absorbers, springs and helper springs for oil leaks and deformation.

• Check of ball joints, tie rods and link ends — checking play and stability under operating conditions.

• Wheel bearing check and condition of seals.

• Exhaust system inspection — from the manifold to the tailpipe, for leaks, corrosion or damage.

When the work is complete, the client receives a written report with all measured parameters, an invoice for all work performed and replacement parts, plus a 12-month warranty on parts and labor.
