Mercedes-Benz is like no other vehicle when it comes to thrill. However, your excitement turns to apprehension when your dashboard displays the message “Service A4 Due”. Is it expensive and what are the steps involved?
A4 maintenance services include everything from spark plug replacements to sunroof maintenance, as detailed in this article. My goal is to explain the average cost of a service and how long it takes the shop to complete the service.
What Is Mercedes A4 Service?
A4 service, part of the Flexible Service System, will ensure your Mercedes continues to run flawlessly for years to come. Your individual driving profile is taken into account when implementing this custom-tailored plan.
Each 10k miles or every 12 months, Mercedes schedules a minor service and a major service alternately. Before, minor visits were performed for A1-A3 and B1-B3. In addition to B-services, A4 is also extremely important for the long-term health of your Mercedes.
A4 Service Mercedes Includes
A4 services should be included in comprehensive maintenance packages that combine standard A services with specific A4 services. There are several major tasks associated with an A4 service.
Air Filter replacement
It is important to replace your air filter when you undergo an A4 service. As a result, fuel efficiency will be improved as a result of optimal airflow and engine performance.
In the combustion process, proper airflow is just as important as fuel and spark, so if the air filter is clogged or dirty, the engine’s efficiency and power will be reduced. One of the simplest but most important repairs you can make on your car is to replace the brakes.
Spark Plug Replacement
The spark plug plays a crucial role in the ignition of fuel-air mixtures in engines. A spark plug’s wear and fouling over time can result in all kinds of problems.
When you have your car serviced by A4, the spark plugs will be checked to see if any damage has occurred. These can result in misfires, rough idling, and a loss of power, which can make driving less comfortable.
Cleaning and degreasing the roof guide rails
You should clean and degrease the guide rails of your Mercedes’ sunroof on a regular basis in order to maintain its smooth operation over time. Dirt, debris, and grease accumulated on the rails may cause the sunroof to become sluggish and become noisy.
Your sunroof will work like it did when you first bought the car after an A4 service removes any dirt or buildup preventing its movement. In addition to saving you money on repair or replacement costs, regular maintenance also prevents motor and component damage.
Synthetic oil replacement
Fresh synthetic oil is added to the engine as part of the A4 service. A synthetic oil used by Mercedes is far more durable than conventional oils, since it resists breakdown for a much longer period of time. It is possible to safely extend the interval between oil changes to 10,000 miles in most circumstances by doing so.
Lubricating effectiveness is gradually lost over time and use even with the finest oils. Old, dirty oil that has lost its protective properties needs to be replaced with new oil that is light and clear. A properly lubricated component will last longer because it will reduce friction and wear.
By ensuring that your Mercedes engine is serviced regularly, you can ensure the engine runs for thousands of miles.
Oil Filter Replacement
In addition to replacing the oil filter, the A4 service includes fresh oil. In order for oil to stay clean and free of contaminants, the filter captures dirt, metal particles, and other pollutants.
By installing a new filter, the debris is trapped once again as it is picked up by the oil and the oil can be filtered to the maximum extent possible. The engine components must be properly lubricated and protected by periodically changing the filter.
Levels of fluids should be checked
In addition to performing a thorough inspection and topping off all necessary fluid levels, Mercedes technicians perform a regular maintenance service on the A4. Ensure that all the essential fluids are at the appropriate levels, such as coolant, power steering fluid, transmission fluid, brake fluid, and windshield washer fluid.
Protecting components and ensuring proper performance are both dependent on maintaining fluid levels at the recommended levels. Service technicians from Mercedes know exactly what fluids to use in each system so they can properly fill and care for them.
Tire pressure check
As part of a comprehensive service performed on an A4, tire pressure should be checked and adjusted. This is an easy task and often neglected. Tires with proper inflation last longer, get better gas mileage, and are more controllable and handleable.
Uneven tire wear, traction loss, and fuel economy reduction are all consequences of wearing out or overinflating your tires. It’s important to check tire pressure periodically even with tire pressure monitoring systems
Components of the brakes should be checked
The Mercedes technician inspects the brakes thoroughly during the A4 service. Besides brake pads, rotors, and calipers, all important components will be thoroughly inspected. It is almost always cheaper in the long run to prevent problems like abnormal wear or damage from getting worse by catching them early.
Keeping you and your family safe between services is made easier by ensuring your Mercedes maintains its optimal stopping power and safety.

Service cost for Mercedes A4
It usually costs $400 to $800 for the dealership to service an A4. There are quite a few fewer service items included in this B3 service than in the previous one you did last year.
The cost is still high despite this. Although Mercedes fluids and parts are more expensive, dealership technicians still use them. If your manufacturer has been servicing your car, you will probably receive a higher trade-in value.
When you want to save some money, think about independent shops with Mercedes expertise. You can ask family members, friends, and coworkers who drive Mercedes for recommendations. It’s a good idea to check any factory warranties before you do any work yourself or hire a third party.
A4 Service Time: How Long Does it Take?
One to two hours of labor are typically required for most A4 services. Depending on location, work amount, and additional repairs, the total shop time varies. The dealer may also charge a higher rate in addition to being faster. Unlike independents, independents usually take more time and cost less.
The wait times during busy seasons like spring and fall are likely to be longer since many car owners opt not to deal with car maintenance during the winter or summer.
