Because Mercedes-Benz cars are built with greater precision, luxury, and cutting-edge technology, they require more care than regular cars. It is essential to stick to the right service plan if you want to keep things running at their best, stay safe, and be reliable in the long term. One of the most important things to do when you own a Mercedes is to get the big service. It is a thorough repair process meant to fix problems before they happen, keep the car’s value high, and stop wear and tear.
Knowing about Mercedes major services helps owners make smart decisions, avoid fixes that aren’t needed, and make sure their car keeps giving them the smooth, refined driving experience Mercedes is known for. This guide goes into great detail about which fixes and inspections are covered, when and how often they should be done, and why choosing the right service provider is essential.
Understanding Mercedes Major Services and Why They Matter
The engine, gearbox, steering, brakes, electronics, and comfort features in high-end cars like Mercedes-Benz are all made with many moving parts that work together smoothly. Over time, even if you drive carefully, parts wear out, and fluids break down.
A significant service is much more than just changing the oil. It includes thorough checks, fluid replacements, and preventive maintenance to ensure all systems work the way they’re supposed to. Ignoring or delaying this work can cause the engine to run poorly, use more gas, and break down, which can be very expensive.
Mercedes major services are required for owners who want their cars to be reliable and give them peace of mind over the long term.
When Is a Mercedes Major Service Due?
Most Mercedes models follow the Service A and Service B schedule. While Service A is considered a minor service, Service B is often the first major service.
Typically, the first major service is due:
- Around 20,000 km or 1 year, depending on driving conditions and model
- Or when the vehicle’s onboard service indicator requests Service B
After the first major service, Mercedes vehicles usually require another major service every 20,000–30,000 km or once every 12–24 months. High temperatures, traffic congestion, and driving habits in the UAE may slightly shorten these intervals, making regular inspections even more critical.
What Is Included in Mercedes Major Services?
Engine Oil and Oil Filter Replacement
Fresh engine oil is critical for lubrication, cooling, and engine protection. During a significant service, high-quality, manufacturer-approved oil is used, along with a new oil filter, to remove contaminants and maintain engine efficiency.
Comprehensive Vehicle Inspection
A complete inspection covers:
- Engine components and mounts
- Transmission and drivetrain
- Suspension and steering systems
- Cooling system and hoses
- Exhaust system
- Belts, pulleys, and seals
These inspections help identify early signs of wear before they become serious problems.
Mercedes Major Services and Fluid Replacements
Brake Fluid Replacement
Brake fluid absorbs moisture over time, reducing braking performance. A significant service includes replacing brake fluid to maintain consistent braking pressure and safety.
Transmission Fluid Check or Replacement
The gearbox fluid may need to be checked or replaced, depending on the type and mileage. It is very important to do this for smooth gear changes and to make the gearbox last longer.
Coolant Inspection and Top-Up
The cooling system is checked for rust, leaks, and the right amount of coolant to keep the car from getting too hot, which is especially important in hot places.
Mercedes Major Services and Brake System Maintenance
Brake Inspection
Wear is checked on the brake pads, discs, and callipers. If it needs to be replaced, it’s usually best to do it during the big service to keep everyone safe.
Parking Brake and Brake Lines Check
Brake lines, hoses, and the parking brake mechanism are checked for leaks, corrosion, or mechanical issues.
Air, Cabin, and Fuel Filters
Engine Air Filter Replacement
A clean air filter ensures proper airflow, improving engine performance and fuel efficiency.
Cabin Air Filter Replacement
Cabin filters are replaced to maintain clean air inside the vehicle and support climate control efficiency.
Fuel Filter Inspection
Where applicable, fuel filters are checked to ensure clean fuel delivery to the engine.
Spark Plugs and Ignition System
During Mercedes’ primary services, spark plugs are checked and replaced regularly on petrol engines. Worn-out spark plugs can cause misfires, reduced fuel economy, and rough engine performance.
The wires and ignition coils may also be checked to make sure the engine starts easily and accelerates smoothly.
Battery, Electronics, and Diagnostic Scans
Battery Health Check
The battery and charging system are tested to prevent unexpected breakdowns.
Electronic System Diagnostics
In current Mercedes cars, electronic control units are very important. Diagnostic checks look for fault codes, software problems, or sensor issues that may not have caused any warning lights to come on yet.
Tires, Suspension, and Steering Checks
Wheel and Tire Inspection
Tire condition, pressure, and alignment are assessed to ensure safe handling and even wear.
Suspension and Steering Components
Bushings, shock absorbers, control arms, and steering joints are inspected for wear that could affect ride comfort or stability.
Does Mercedes Major Services Cover Brake Fluid and Cabin Filters?
Yes, brake fluid replacement and cabin air filter replacement are standard components of a significant service. These elements are essential for safety, comfort, and maintaining the premium driving environment expected from a Mercedes.
How Often Should Mercedes Major Services Be Done?
Most owners should plan Mercedes major services every:
- 12 months or 20,000–30,000 km, whichever comes first
Drivers who frequently experience heavy traffic, short trips, or extreme heat may benefit from more frequent inspections to protect engine and transmission components.
Is a Major Service Necessary If the Mercedes Is Running Fine?
Yes. Luxury cars are designed to keep running well even as parts wear out. Many problems occur in the background and go unnoticed until it’s too late.
Preventing problems rather than fixing them is a big part of service. Dealing with issues early on saves money, keeps people safe, and maintains the home’s selling value.
Difference Between Minor and Major Mercedes Services
A minor service typically includes:
- Engine oil and filter change
- Basic safety checks
A Mercedes major services includes:
- All minor service tasks
- Fluid replacements
- Filter changes
- Spark plug inspection
- Brake system service
- Full diagnostic scanning
This depth of care is why Mercedes major services play a crucial role in long-term vehicle health.
Cost of Mercedes Major Services
The cost varies depending on:
- Model and engine type
- Mileage and service history
- Parts and fluid requirements
While Mercedes major services costs more than a minor service, it significantly reduces the risk of expensive repairs later. Investing in proper maintenance always proves more economical over the vehicle’s lifetime.
Dealership vs Independent Mercedes Garage
Mercedes drivers are not limited to only going to dealerships. A trustworthy, independent shop with Mercedes-trained technicians can perform basic repairs using only approved parts and fluids, all while adhering to service standards.
When I choose an experienced Mercedes garage near me, these things usually happen:
- Service tailored to you
- Clear pricing
- Less time spent on repairs
Many independent garages offer Mercedes roadside assistance as a bonus, making car ownership stress-free.
