Mercedes A9 Service [Checklist & Cost Explained]

Mechanics perform scheduled maintenance on the Mercedes A9. After a B8 service or approximately 10,000 miles, you should have a short checkup if you have been careful with maintenance.

In addition to examining the brakes, engine, and gearbox of your car, a qualified technician performs a thorough inspection of all its systems. No matter how long you plan to keep your Mercedes, factory-recommended maintenance such as the A9 will help it run at its best and keep its value intact.

Mercedes A9 Service Includes

Here is a comprehensive checklist of all the services that need to be performed on the A9:

1. Oil change

After the A9 is overdue, the first thing that should be done is an oil change. Engine oil changes are crucial to the maintenance of your car because they prevent early wear and maintain smooth performance. Eventually, the oil gets dirty, so the oil filter needs to be changed. Only complete synthetic oil is used in Mercedes engines. Due to its longer life and slower degradation, synthetic oil should be changed more often than conventional oil.

Your engine’s protection begins to deteriorate even after thousands of miles, even if you use synthetic oil. Old oil may lose its lubricating properties due to oxidation. A new oil cover and cushion must be installed on every valve cover, piston, and bearing. This will prevent damage by reducing friction and wear.

2. Changing the oil filter

As part of the A9 service, the oil filter needs to be changed. Located inside the engine, the oil filter filters engine oil. It is a tiny, circular filter. An oil filter is essential to the functioning of your Mercedes engine because it removes debris from engine oil before it enters the engine. Oil filters that are obstructed or unclean can cause damage to an engine over time, resulting in poor performance. Your car’s old oil filter will be removed and replaced by the technician doing an A9 service.

3. Inspect the fluid levels

The A9 service performed by Mercedes technicians includes checking the fluid levels of your car to make sure they are at the recommended levels. They will also check the oil level along with power steering, brake, coolant, gearbox, and windscreen washer fluids.

The simplest task of maintaining these fluids falls under the radar of car owners, despite their importance. That’s handled by the experts. Parts operate smoothly with cooling, lubrication, and fluids. Low levels can cause overheating and wear.

4. Transmission filter replacement

Dirt and debris might get into the Mercedes’s gearbox system via a small, porous disc called a gearbox filter. The fluid flowing through the gears can be clogged by this filter over time.

5. Checking the pressure of tires

Tire pressure and condition are checked as part of the A9 service. A technician will also inspect the tread patterns of each tire in addition to inspecting the damage, tread wear, and tire pressure. At the end of your service session, your Mercedes technician will adjust your A6’s tire pressure, including your spare if available. It cannot be overstated how important it is to keep tires properly inflated.

Firstly, proper tire air pressure prolongs the life of tires. The wear and degradation of a tire are uneven and accelerate if it is underinflated or overinflated. This can save you money, since tire replacement can cost $200 to $300 per tire. A proper tire pressure will also improve braking and handling. When the tires are inflated as recommended, they provide more grip and responsiveness. Tire wear is also reduced by safe tire pressure, along with reducing rolling resistance. It can be done this way in order to maximize fuel efficiency.

6. Take a close look at the brakes

As part of its service schedule, Mercedes A9 have their brake system thoroughly inspected. In order to ensure the correct operation and condition of each part, technicians will carefully inspect them. During caliper opening, corrosion or leaks on the pistons are examined.

In addition to checking brake pads with a gauge while the calipers are open, the calipers are also checked for wear, damage, and thickness. Inspections and analyses of brake rotor thickness and wear patterns are conducted to find uneven wear issues. Additionally, brake lines, hoses, and fittings are inspected visually. A technician looks for signs of chafing and leaks.

Service cost for Mercedes A9

Local dealerships charge between $300 and $600 for A9 service appointments. Despite what you may think, Mercedes maintenance costs are comparable to those of other brands. That’s because you’re paying for the same parts and technicians. The peace of mind provided by high-end cars is worth it to many people.

An independent service with experience servicing Mercedes vehicles may be able to save you some money. They typically use genuine Mercedes parts, so their labor rates are lower than dealerships.
