Driving your Mercedes-Benz is like no other experience. Suddenly, your excitement turns to apprehension when your dash lights up with “Service A4 Due”. Is there a cost involved and what’s involved?
Including everything from spark plug replacement to sunroof maintenance, this article explains every part of the A4 maintenance service. The shop will take a while to complete the service and reset the service notification once it’s completed. I’ll go over average service costs and how long it takes.
How Does a Mercedes A4 Service Work?
A4 service is part of the Flexible Service System that keeps your Mercedes running smoothly for years to come. Your driving profile determines when and how you receive care.
During the first 10k miles or 12 months after purchase, a minor and major service is scheduled alternately. This is the fourth minor service after the A1-A3 and B1-B3 visits. In spite of being less complicated than B-services, A4 also plays an important role in keeping your Mercedes running smoothly.
What is the best time to service an A4?
After 70,000 miles or approximately one year after having an A3 service, Mercedes vehicles require an A4 service around the 70,000 mile mark.
Having trouble remembering when your car should have a maintenance check? No worries. There are various messages that will appear on your car when it’s time for an A4 service, such as “A4 Service Due”, “A4 Service Overdue by 40 Days”.
What Is Included in an A4 Service?
In addition to standard A services, A4 services are an important component of a comprehensive maintenance package. An A4 service involves the completion of the following major tasks.
Replace Air Filter
You should expect that an air filter replacement will be part of the A4 service. You’ll get better fuel mileage if you keep your engine running smoothly and smoothly.
The air filter plays a crucial role in the combustion process, so if it is dirty or clogged, it can reduce engine efficiency and power. This is one of the easiest, but most crucial maintenance jobs you can perform on your vehicle.
Replace Spark Plugs
During engine ignition, spark plugs are crucial to the process of igniting the fuel-air mixture. A dirty spark plug can cause all sorts of problems as it wears down over time and mileage.
During an A4 service, a spark plug check is performed to determine if it needs to be changed in order to prevent misfires, rough idling, and a loss of power. These issues can negatively impact the fuel economy and comfort of your car.
Clean Sunroof Guide Rails
To keep your Mercedes’ sunroof operating smoothly and quietly over time, make sure you clean the guide rails and degrease them regularly. It may get sluggish or noisy when the sunroof opens or closes as the rails collect dirt, debris, and grease.
Your sunroof will work just like it did when you first bought the car after an A4 service removes any dirt or buildup preventing the sunroof’s movement. In addition to preventing sunroof damage, this regular maintenance can also save you money on repairs and replacements.
Replace Synthetic Motor Oil
A4 engines are serviced by draining the old oil and replacing it with fully synthetic oil as part of the service. There is no comparison between Mercedes’ synthetic oil and conventional oil in terms of its ability to resist breakdown for a long period of time. It is thus possible in the majority of cases to extend the interval between oil changes to 10,000 miles safely.
The effectiveness of lubricating oil deteriorates gradually over time even when it is made from the finest oils. As a result of this oil change, the old, dark, dirty oil has been replaced in order to protect the engine from further damage. When components are properly lubricated, friction and wear are reduced, making them last longer.
Maintaining your Mercedes engine for literally hundreds of thousands of miles starts with an oil service for your A4.
Replace Oil Filter
Oil filter replacement is also included in the service for the A4. The filter is responsible for capturing dirt, metal particles, and other contaminants in the oil as well as lubricants in the oil so it can flow smoothly through the engine.
As soon as the oil is filtered and the filter is cleaned, debris will once again be picked up as the oil flows through and is filtered once again. In order to protect engine components and ensure optimal lubrication, filters must be changed periodically.
Check Fluid Levels
All fluid levels will be inspected and topped up as necessary as part of the Mercedes A4 service. They’ll check all the essential fluids and add more if necessary, including coolant and power steering fluid, transmission fluid, brake fluid, and windshield washer fluid.
In order to protect components and ensure proper operation, it is important to maintain fluid levels at the recommended levels. Service technicians from Mercedes know exactly what fluids to use to fill and maintain each system, based on factory specifications.
Check Tire Pressure
When an A4 service is performed, it is easy to forget to check the tire pressure and adjust it. It’s easier and safer to handle and control when your tires are properly inflated.
Uneven tire wear, poor traction, failures, and poor fuel efficiency are all consequences of underinflated or overinflated tires. It’s important to check your tires regularly regardless of the tire pressure monitoring system.
Check Brake Components
The Mercedes technician inspects the brakes thoroughly during the A4 service. It is important to inspect all brake component parts, such as pad, rotor, and caliper, thoroughly. You can almost always save money by detecting problems early on such as abnormal wear or damage before they get worse (almost always before they get worse).
It keeps your Mercedes safe and keeps your family safe between services by ensuring optimal stopping power and safety.
