This article discusses the cost and checklist of a Mercedes A5 service, as well as how it works.
When you take good care of your vehicle regularly, you can maintain its performance and keep it running smoothly. The following information is important if you own or are thinking of buying a Mercedes-Benz.
The letter “A” indicates required maintenance and helps keep your Mercedes running smoothly. This code appears on Mercedes car service intervals (for the A-Class, B-Class, and C-Class).
The letter “A” and the number “5” indicate an interval of thousands of miles. An A5 indicates the fifth service interval.
What Do A5 Services Include?
Three additional tasks specific to the Mercedes A5 are included in the Mercedes A5 service. As an example of how the services were performed and how important they are, here are the details:
Filter replacement
In an A5 service, the air filter is one of the most important part. Air filters can drastically improve engine airflow, performance, and fuel economy, which is extremely important with the high cost of gas today.
The engine loses power and efficiency when an air filter is clogged or dirty. Your Mercedes engine runs at its peak performance with something as simple as changing the filter. It is possible that larger problems in the future could result if this simple maintenance item is neglected.
Spark plugs should be replaced
It is necessary to use spark plugs when compressing air and fuel to generate power. During the A5 service, you should replace worn spark plugs with new OEM ones to prevent misfires, rough idles, loss of power, and poor fuel economy.
Spark plugs must be properly gapped and fresh in order to ensure smooth, efficient combustion. With this relatively simple maintenance, you’ll be able to maintain your Mercedes between service appointments.
Fluid replacement for brakes
Replacing the brake fluid is an important part of an A5 service. It is common for brake fluid to absorb moisture and contaminants during the life of a brake system, reducing the effectiveness of braking.
Depending on the circumstances, old brake fluid can lead to unpredictable pedal movement, poor braking performance, and even brake failure. When Mercedes brake fluid is used, you can maintain responsive brakes and ensure safe stopping power.
Synthetic Oil replacement
During an A5 service, the engine oil will be changed, as with any routine maintenance visit. Mercedes recommends using full synthetic oil, which is more resistant to breakdown than conventional oil, to replace the old, dirty oil.
Using this high quality oil, you will be able to expand your oil service intervals by 10,000 miles without compromising the amount of lubrication that your vehicle receives.
Oil Filter Replacement
A5 services also include the replacement of the oil filter and engine oil. In addition to capturing contaminants in oil, filters prevent them from circulating in the oil, which causes unnecessary wear and tear on engine components.
In order for the oil to flow more freely, it should be changed at regular intervals or the oil may become contaminated.
Maintain fluid levels
A5 service recommendations include checking and replenishing transmission, cooling, and power steering fluids. Maintaining proper fluid levels is often overlooked by car owners.
During maintenance, Mercedes technicians ensure the fluid levels in all systems (and conditions) are at the recommended level and add more as needed. It is the technician’s responsibility to note anything that seems amiss (e.g. burnt transmission fluid) and address it at the same time (with the customer’s approval).
Maintain proper tire pressure
It is also important to check and adjust the tire pressure as part of the A5 service maintenance. The inflation pressure in your tires determines the lifespan of your tires, the fuel efficiency of your vehicle, and the safety and comfort of your ride.
Overinflated and underinflated tires wear quickly too, resulting in early tire replacement. Not only do they reduce fuel economy and traction, but they also compromise fuel economy and traction. A glance at Mercedes’ price list will probably let you know how expensive their tires are.
A manual inspection will be required during A5 service and between services to ensure tires are inflated to their optimum performance specifications.
Brake component check
An extensive inspection of the brake components is carried out during a Mercedes A5 service. Gauges are used for measuring the thickness and wear of brake pads.
There are three steps in the inspection process: finding uneven wear, warping, and checking rotor thickness. Inspections of the brake pistons are performed by opening the brake calipers.
A visual inspection is performed to look for leaks, cracks, and damage to brake lines, hoses, and fittings.
The comprehensive inspection will uncover any issues that may threaten the safe, reliable operation of the brake system.

Cost of servicing a Mercedes A5
An A5’s service costs between $400 and $800 at a Mercedes dealership. The factory costs a lot for parts and technicians.
If you’re trying to find an affordable Mercedes or German vehicle, seek out independent shops that specialize in these vehicles. Get to know what other people think of you. Check to make sure a third-party service won’t void your factory warranty or aftermarket warranty.
It is generally more expensive to maintain a Mercedes-Benz dealership, but technicians must meet Mercedes requirements and be competent. Certified mechanics using approved methods can provide you with peace of mind.

What is the turnaround time for A5 services?
This service usually takes between one and two hours, but shop, season, and other repairs can affect the overall time. Dealerships can turn around items faster, but they also charge a higher rate.
Independent shops may take longer to accept your model unless it is well known to them. Wait times during spring and fall are longer due to the accumulation of jobs throughout the day. A technician’s availability also affects turnaround times.
Reset Service Notifications for Mercedes A5
The service notification displayed on your vehicle’s dashboard can be reset without scheduling an appointment with the dealer. Steps to follow:
- To illuminate dash lights without starting the engine, insert the key in the ignition and turn it to the first position.
- Scroll through the display using the steering wheel buttons.
- Removing the key from the ignition and turning it off.
- Put the key back in the first position, then turn it back around.
- Keep the “OK” and “Call” buttons pressed together for 3-4 seconds while in the first position.
- Select “OK” from the “Vehicle Data” display.
- Select “Full Service” then “Assist Plus” and then “OK”.
- Choose “Confirm Service”, then select “OK” before selecting “Yes”.
