Mercedes-Benz automobiles from old model years may alert the driver to bring it in for “Mercedes-Benz A0 Service,” or various combinations of A/B followed by a number between 0 and 9.

The letters A or B that come before each number denote the additional service item(s) that must be completed in addition to Service A or Service B.

For certain models, the Mercedes-Benz A0 Service highlights the need to add sunroof cleaning, lubrication (if necessary), and spark plug service. The Mercedes A0 Service applies for models starting from 2009 and newer.

For newer model vehicles, a Mercedes-Benz Service A message will appear on your dashboard if one of the additional services is necessary. The mechanic will inform you if any of the additional tasks are needed when you bring your car in for service.

It’s also important to note that some Mercedes-Benz automobiles, particularly those from 2015, those with V12 engines, and those made by AMG, have particular maintenance requirements. If you own such a car, be sure to let your service provider know so they can give you maintenance advice.

Mercedes A0 Service entails the following


Simply put, a Mercedes AO service includes an engine oil and filter change, coolant level inspection, windshield washer fluid check, and brake and power steering fluid level inspection. This service usually costs between $250 and $350 at Mercedes dealerships.

  1. Engine Oil Change

An oil change is typically the first procedure carried out during a Mercedes A0 servicing. Every car needs routine oil changes, and Mercedes Benz is no exception. When it comes to how the engine functions over time, the engine oil is of great importance.

The motor oil lubricates and cools the moving internal components of the engine. The technician will completely drain the old oil from your engine and replace it with brand-new oil during an engine oil change. [2]

  1. Oil Filter Change

The replacement of the oil filter is the second procedure that you may anticipate during a Mercedes A0 servicing. Engine oil contaminants that might harm your car must be filtered out by the oil filter [3].

The filter is also in charge of keeping any particles from getting inside the engine. The oil filter may eventually jam up with particles, necessitating replacement. The technician will remove the old filter and install a new one after changing the engine oil.

  1. Coolant Inspection

The primary A0 service activities are usually concluded by performing an engine oil change and an engine oil filter replacement. Inspections start soon after.

The mechanic will check the level of the engine coolant and top it up if necessary. You must ensure you have enough coolant to protect the engine from overheating. [4]

  1. Brake Fluid Inspection

The technician will check the brake fluid after checking the level of the engine coolant and top it off if necessary. Your Mercedes’s stopping power is improved by the brake fluid [5].

When you step on the brake pedal, the fluid transmits the force from your foot to the wheels to slow down the vehicle. It makes stopping your car easier than it would otherwise be.

  1. Power Steering Fluid Inspection

The Electric Power Steering (EPS) technology [6], which requires no fluid, is available on more recent Mercedes models. The hydraulic power steering (HPS) system on older models, however, necessitates routine checking and maintenance of the power steering fluid level. [6],

The mechanic will check the power steering fluid level if your Mercedes has hydraulic power steering and fill it up if it is too low.

  1. Windshield Washer Fluid Inspection

The technician will check your windshield washer fluid last. The windshield washer fluid cleans the windshield when it becomes dirty from rain, dust, or road debris.

The mechanic will open the reservoir’s cap to check the level of windshield washer fluid and make sure it is sufficient.  They will replenish it if necessary by adding extra windshield washer fluid.

Mercedes A0 Service Cost


As you might expect, the price of this service will differ based on where you reside and where you take your Mercedes for servicing. A Mercedes A0 service typically costs between $150 and $250 at a standalone garage and $250 to $350 at a Mercedes dealership.

To save money, you can do the DIY A0 service of changing the oil and filter yourself before bringing the vehicle to a Mercedes dealership for other inspections and servicing.
