Mercedes A7 Service  [What’s Included & Checklist, Cost]

If you want your Mercedes-Benz to run smoothly, last a long time, be reliable, and hold its value, you need to regularly service it.

In my experience as an auto technician, Mercedes Benz owners tend to neglect their cars. They drive them to mechanics until they break down and hope that they can fix them.

Your car could suffer from poor service and increase long-term costs by using this strategy.

This article will discuss Mercedes Benz’s “A7 service” and what’s included. Let’s begin.

What Is Mercedes A7 Service?

In accordance with your Mercedes service schedule, you should perform an A7 service every 12-24 months or whenever you see a maintenance message on your dashboard indicating that you need to perform an A7 service.

In addition to the A service, the A7 service includes some additional tasks. Seven other maintenance methods are available for Mercedes Benz vehicles.

What Is Included In The Service?

The next step is to examine how the technicians perform this particular service. The Mercedes A7 comes with the following features:

Changing Of Engine Oil

The first step in Mercedes A7 service is to change the oil and filter.

The technician will also add synthetic oil to the system and clean the filter housing after removing the old oil.

A regular oil change is crucial to the longevity of your engine, as it prevents corrosion, wear, and tear, and keeps it cool.

The oil in your engine also promotes smooth and efficient operation in addition to lubricating its moving parts.

Changing The Engine Oil Filter

Next, the technician will replace the oil filter in your engine.

Debris and contaminants can damage your engine oil when they get into the oil through your vehicle’s filter.

Transmission Oil Replacement

Your transmission fluid will be changed as part of this A7 service.

Transmission fluid is a specialty oil that keeps your vehicle’s transmission lubricated and cool.

Dirty transmission fluid can cause damage if left unreplaced.

Transmission Filters Replacement

Your transmission fluid is protected from contaminants by transmission filters. During the technician’s visit, this filter will be replaced and tested.

Tires Inspection

The technician will then check the tires on your car.

The tread and pressure of your tires play an important role in the overall condition of your vehicle.

In case one or more of your tires are low on air pressure, your technician will fill them up.

The tread or sidewall of your tires should be replaced as soon as you notice a crack.

Brakes Inspection

A mechanic will inspect and check your car’s brakes, as well as make sure they are working properly.

In addition, they will inspect your Mercedes’ brake system for leaks that could damage other components.

Changing The Brake Fluid

The Mercedes A7 service also includes changing the brake fluid, which is crucial to the brakes’ efficiency.

Mercedes brake fluid will be flushed out and replaced with a new supply that meets the manufacturer’s specifications.

Flushing The Cooling System

It is necessary to use engine coolant to maintain an engine’s proper temperature.

The technician will replace the coolant after flushing it out.

Reset Maintenance Service Count

The Mercedes A7’s maintenance indicator is reset as a final step.

Maintaining a service schedule makes it easier to keep track of how often your vehicle needs to be serviced.

During the checkup, the technician will ensure that everything is working properly in your Mercedes. A once-over will be performed after the maintenance indicator has been reset.

When Should An A7 Service Be Done?

The A7 service is typically performed after 130,000 miles or in the 13th year of a Mercedes’ lifespan. This minor service is required about one year after the last major B6 service.

A handy reminder will appear on your dashboard when it’s time to service your Mercedes, like “A7 Service Due,” “A7 Service in 30 Days,” “A7 Service Overdue by 15 Days,” and “Service Code: A7.”. Your Mercedes will appear with these reminders when it’s time for service. The recommended time can be moved up or down a few days.

Your Mercedes service notifications will let you know when your next A7 appointment is.

Why Is An A7 Service So Expensive?

A variety of factors contribute to Mercedes maintenance costs being higher than other vehicles:

  • High-quality, engineered parts are used in Mercedes vehicles to ensure optimal performance. Parts, fluids, and filters of premium quality are more expensive.
  • It takes extensive, ongoing training for Mercedes technicians to maintain these complex vehicles. Since they know your model and make well, they charge more for labor.
  • Furthermore, Mercedes dealers heavily invest in equipment for scanning and assessing the quality of its meticulously engineered vehicles. The cost of purchasing such specialized equipment is high for dealerships.
  • Mercedes may also charge a premium maintenance rate, in line with other luxury brands. Due to Mercedes’ reputation for high quality service, Mercedes owners expect the same.

Mercedes A7 Service Vs. Generic Auto Shops

Specialized Knowledge

Unlike generic auto shops, this one goes the extra mile. Mercedes technicians are equipped with in-depth knowledge of Mercedes vehicles to ensure accurate diagnosis and repair.

Genuine Mercedes Parts

Mercedes-Benz parts are what your A7 deserves. Only authentic components are used by A7 service in order to protect your luxury vehicle’s integrity.

Warranty Considerations

By choosing A7 service, you can preserve the warranty on your vehicle. The use of a generic auto shop could result in you losing your warranty, which could lead to financial hardship in the future.

How Long Does An A7 Service Take?

Mercedes A7 Service

Most dealerships take about an hour to perform an A7 service. Your car’s total time in the shop can be affected by several factors:

  • Location: Bigger facilities with well-trained staff tend to perform better than smaller facilities with untrained workers. It is also helpful to have technicians who perform routine maintenance only.
  • Time of Year: Spring and the days leading up to winter are extremely busy for auto service shops. If more cars are in the shop, there will be a longer wait.
  • Extra Repairs: Any additional work beyond the standard A7 items will take more time. It is more likely that you will discover other maintenance issues when your car has well over 100k miles.

The A7 task may be completed in one hour by a skilled technician, but shop delays, seasonal demands, and additional repairs can easily extend the visit’s duration. The shop may need to solve some cases for three, four, or even more hours. Before contacting the shop, make sure you know how much time you have.

Can I Do An A7 Service Myself?

Due to the complex nature of Mercedes maintenance, most owners are better off taking their cars to a professional shop.

Mercedes tools and advanced technical expertise are necessary to meet factory specifications. These sophisticated vehicles can suffer mechanical problems, safety hazards, and even void warranties if serviced by an amateur.

In the event that you are a knowledgeable home mechanic who accepts the risks and fully understands the service procedure, servicing Mercedes yourself may save you some money. There may not be as much savings after purchasing parts, supplies, and tools.

The process of developing a toolkit, searching for better-priced quality parts, and consuming fluids and filters eventually makes DIY servicing more cost-effective. Due to the upfront costs and experience required, Mercedes owners prefer professional service initially.

How To Reset An A7 Service Notification On A Mercedes

The A7 service notification can be reset at home, whether you completed the service yourself or the shop forgot.

It is very well explained in this video how Mercedes service notifications work. The actual procedure may differ depending on the year and model.

How Much Is The Cost Of Mercedes A7 Service?

Lastly, let’s look at the cost of servicing an A7.

The cost of A7 service can vary from $420 to $600 (£350 to £500) depending on your location.

If you have all the necessary parts and labor with your warranty, you may be able to recoup some of the cost.
