Mercedes Benz is known for being one of the best luxury car manufacturers in the world.
Their cars are known for their excellent build quality and reliability, which means that it can be hard to convince yourself that your Mercedes needs servicing.
However, it is important to remember that just like any other car brand, even a Mercedes Benz will need some maintenance work done on it at some point to improve the engine efficiency and longevity of core components and one of that maintenance works is an A3 service.
In this article, I will explain what an A3 service is on your Mercedes, what it includes, and how much it costs to get it done.
I have included a “Mercedes A3 service” checklist at the end of the article, so be sure to check it out.
What Does A3 Service Mean on a Mercedes?
In short, A3 service is part of the Mercedes maintenance schedule, where A indicates oil and filter change, tire inspection, and other fluid checks and 3 indicates spark plugs and cabin and pollen filter replacement.
Now, let’s look at the A3 service in more detail.
What Does Mercedes A3 Service Include?
As a seasoned auto mechanic, I would say the A3 service is one of the most important maintenance tasks to complete on your Mercedes, as it includes a number of important items. These include:
1. Oil and Filter Change:
The first thing the A3 service includes is an oil and filter change.
This is important to make sure that you have fresh lubricant in your engine, which will help prevent wear on your moving parts and protect them from corrosion.
Engine oil and filter on your Mercedes do get dirty over time as you drive your vehicle, so the A3 service is a great way to ensure that you have fresh oil when it’s needed most.
2. Tire Inspection:
After changing the oil, it’s time for a tire inspection.
This will ensure that there are no nails or other pieces of metal stuck in your tires, which could cause a blowout when driving at high speeds.
The tire pressure and condition are also inspected; having too much or too little air in your tires can cause them to wear out faster or have less traction on the road.
3. Air Filter Change:
The air filter on your Mercedes is a very important component of your vehicle, as it filters out dirt and debris that could get sucked into the engine.
The air filter is changed at every A3 service, so you can be sure that all contaminants are removed before they reach sensitive components inside your car.
4. Pollen Filter Change:
The pollen filter is another very important component of your Mercedes, as it filters out dirty air inside the vehicle ensuring there is fresh air for you and your passengers.
5. Brake Fluid Replacement:
The brake fluid of your Mercedes is a very important component as it controls the braking system of your car.
It ensures that there is enough pressure for the brakes to work properly, and it also helps prevent any corrosion from forming on your brakes and calipers as well.
6. Spark Plug Replacement:
Another important task that is included in the Mercedes Benz A3 Service is the replacement of the spark plugs.
Spark Plugs play a vital role in the engine of your Mercedes, as they ignite the fuel in your cylinders and cause an explosion that turns it into mechanical energy.
when plugs go bad, it can cause your engine to misfire and cause the Benz to run poorly.
When is a Mercedes A3 Service Schedule?
The a3 service schedule is different for every vehicle, but it’s a good idea to get your Mercedes Benz A3 Service done every 12-15 months or 10 000- 14 000 miles (16 000 – 22 000 KM).
Depending on how often you drive your car, you may need more frequent maintenance services performed.

How Much Does Mercedes A3 Service Cost?
Finally, let us look at how much this service costs.
A quick disclaimer: the cost of this service will vary, depending on where you live and other factors.
Depending on where you take your Mercedes for an A3 service, here are the average costs
1. Mercedes Dealership:
The average cost of an A3 service at a dealership is $500 – 780 (£422-650).
This is a rough estimate from my experience as an auto technician and what others have told me, as well as from various forums. This is not the cheapest option available to you
2. Independent Garage:
The average cost to get an A3 service at an independent garage can range anywhere between $289-532 (£24-450).
This is a more economical option than taking your Mercedes to a dealership, but it will still cost you more than if you do the service yourself.
