For those who plan to perform the service themselves, I have included a checklist at the end of the article.

What Is A Mercedes A9 Service?

If you receive a service reminder on your dashboard, you need to service your Mercedes-Benz every 10 000-15,000 miles.

What Does The Mercedes A9 Service Include?

The A9 service has the following features.

Changing The Oil

First, you have to change the oil when you take your Mercedes for an “A9 service.”

Oil changes are essential to prevent premature wear on your vehicle and keep it running smoothly.

Since oil gets dirty over time, replacing the oil filter and disposing of the old oil is important.

Changing The Brake Fluid

The Mercedes-Benz A9 service also includes an engine inspection along with the brake fluid change.

To keep your vehicle’s brakes working smoothly, a hydraulic system uses a specific type of fluid.

This liquid should be replaced every few months to prevent contamination, which can cause your vehicle to have difficulty stopping when you need it most.

Transmission filter replacement

When a transmission is changed in a Mercedes, the transmission filter captures any dirt or grit that enters the transmission system.

Fluid may back up in the gears if the filter clogs over time.

In the future, you might have to pay for expensive and lengthy repairs as a result.

Oil Filter Replacement

An oil filter change is the next step in the A9 service. An oil filter inside the engine filters engine oil in a circular pattern.

The oil filter protects the engine oil from dirt infiltration in Mercedes engines.

Oil filters can clog or become dirty over time, resulting in engine damage.

During an A9 service, your old oil filter is removed, and a new one is installed.

Changing The Automatic Transmission Fluid

Changing the automatic transmission fluid (ATF) is the next step in the A9 service.

Lubricating and cooling fluid is used in Mercedes-Benz automatic transmissions.

You should use fluids like this to ensure your vehicle’s transmission runs smoothly and lasts as long as possible.

The transmission may overheat or even seize if left unattended.

Tire inspection and tire pressure check

Our A9 service also includes an inspection of tire pressure and condition.

The technician will inspect all four tires in addition to checking their pressure levels and tread wear.

What Is The Cost Of Mercedes A9 Service?

The A9 service is part of a series of maintenance appointments that keep your Mercedes-Benz in good shape. You’ll need this service after 170,000 miles or about one year after your last B8 service if you’ve followed your recommended maintenance schedule.

A9 is essentially a comprehensive tune-up, which checks and replaces worn out parts after 100k miles. You must have maintained your Mercedes well if you have reached this mileage mark! Thanks to your diligent maintenance, you’re reaping the rewards.

There’s no need to worry about tracking when your Mercedes’ A9 service is due – the vehicle will remind you automatically. The onboard computer tracks your service history as well as your mileage. As soon as you reach the specified mileage or have been without an A8 service for one year, your car will alert you when it is time to schedule the A9 service.

What Makes An A9 Service So Expensive?

The following factors are taken into account when determining the Mercedes service price:

  • Parts, fluids, and filters of the highest quality are used to meet Mercedes’ strict specifications. Due to their premium quality, these components cost more, but they ensure optimal performance.
  • Mercedes technicians must undergo extensive and ongoing training to be able to service these complex, high-tech vehicles effectively. Their specialized expertise justifies their higher labor rates.
  • There is a substantial investment by Mercedes dealers in diagnostic scanners and tools necessary to service Mercedes vehicles. These specialized technology equipments are very expensive to purchase.
  • It is common for Mercedes, like other prestigious brands, to require expensive maintenance. Mercedes owners expect their service experience to live up to the brand’s esteemed reputation. Additionally, their waiting room will have better coffee and a cleaner dealership bathroom.

Ultimately, you’re paying for high-quality parts, high-quality technicians and top-of-the-line tools, as well as an overall superior service experience.

How Long Does An A9 Service Take?

A9s typically require 1-2 hours of service. It is possible that you will have to wait longer in the shop if the following factors apply:

  • Shop/Location: A larger dealership or shop with more technicians and service bays is typically more efficient than a smaller one. The dedicated technician can also work more quickly if he or she focuses only on routine maintenance.
  • Seasonality: Repair shops are extremely busy in the spring and in the months leading up to winter. This may result in longer turnaround times.
  • Additional problems found: If additional maintenance issues are detected during the A9 service, they may add time to the appointment. In vehicles with high mileage, more repairs are likely to be needed.

Any or all of the factors above can extend the total visit to 3 hours or longer, even though the A9 itself may only take one or two hours. The shop may be able to tell you how long the wait will be up front, depending on how much time you have.

Is It Possible To Perform An A9 Service On My Own?
