4 Things To Look Out For During Mercedes Repair [As Of 2023 ]

Mercedes-Benz models from 1997 and later need to undergo two types of scheduled services: Assyst+ Service A and Assyst+ Service B.


The built-in ASSYST PLUS system in a Mercedes lets the driver know when their car is due for servicing, showing information such as remaining mileage or time before the next due date.


However, not all car owners know what to look for during Mercedes-Benz repairs and maintenance since these above-mentioned scheduled services involve various parts and checks for every mileage reached.


But the carmaker has intended these servicing packages for all Mercedes-Benz vehicles to ensure optimal performance. 


Knowing what to expect when you visit a Mercedes-Benz workshop or bring your car in for servicing should help you set expectations and ensure a long life span for your vehicle.

What Is The Mercedes-Benz ASSYST PLUS System?

It’s been more than 25 years since Mercedes-Benz introduced diagnostic systems into their vehicles. Its purpose is to inform drivers when to take the car for servicing, repair, or replacement.


A symbol will appear on the instrument panel, reading either “Service A” or “Service B”. These symbols indicate the servicing package the car needs, with the requirements increasing and becoming more time-consuming as it counts down to “Service H”.


All these reasons make Mercedes servicing crucial for every car owner. You must bring the vehicle to a Mercedes specialist when the system tells you to ensure optimal performance and avoid expensive repairs.


With the help of computer algorithms, the ASSYST PLUS system determines vehicle components that need repair, such as:


  • Oil filter
  • Brake fluid
  • Brake pads
  • Spark plugs
  • Fuel filter
  • Transmission fluid
  • Engine oil
  • And other car parts

Service A covers basic preventative maintenance work to ensure the vehicle is in good shape and to avoid costly faults and damages in the long run.


Mercedes-Benz cars generally need to undergo their first Service A maintenance once they reach 15,000 of mileage or after one year of ownership has lapsed (whichever comes first).


The owner will then need to take their vehicle to a car workshop approximately every 30,000, 60,000, 120,0000 kilometres, etc.


As not all Mercedes-Benz owners have the same driving habits, the timeframe of servicing is on a case-by-case basis. The car will determine the exact schedule with the help of its Flexible Service System.


Here’s what to expect during a Mercedes-Benz Schedule A maintenance:


  • Replacement of oil filter
  • Tyre rotation and inflation check
  • Fluid level inspections and checks
  • Reset maintenance counter
  • Full Xentry Star Diagnostic health inspection check
  • [OPTIONAL] Replacement parts for car battery, brake pads, rotors/discs, wiper blades, air conditioner compressor, etc.
3. Mercedes-Benz ASSYST+ Service B

The Mercedes-Benz Service B covers similar preventative maintenance but with a different scheduling interval.


Instead of every 10,000 kilometres, your Mercedes-Benz will need to undergo Schedule B servicing every 30,000 km.


Unlike the first package, this servicing takes much longer and can last anywhere from 4 to 6 hours. It includes the following:


  • Fully synthetic engine oil (Mercedes-Benz-approved lubricant)
  • Air filter
  • Oil filter
  • Fuel filter (for diesel engines).
  • Dust/combination filter
  • Tyre rotation/inflation
  • Wheel alignment
  • Air conditioning
  • Full Xentry Star Diagnostic health inspection check
  • [OPTIONAL] Replacement parts for car battery, suspension items, genuine Mercedes-Benz brake pads and rotors/discs
4. Why Should You Service Your Mercedes-Benz?

Not many people can say they own a Mercedes-Benz in Singapore. It’s a luxury only a few can afford, so taking care of and reducing wear and tear on it should be every owner’s priority.


If you want peace of mind and to keep your Mercedes vehicle running for a long time, follow its servicing schedules. A genuine Mercedes-Benz repair workshop can conduct a thorough inspection to diagnose common issues or recommend part replacements.


Routinely bringing your vehicle to an auto service centre has several advantages:


  • Prevent major repairs: Routine maintenance can prevent maintenance concerns in the long run. Additionally, you save on expenses and reduce the car’s likelihood of breaking down or stalling while on the road.
  • Covered with warranty: A reputable workshop in Singapore can prevent instances of voiding your Mercedes-Benz’s warranty. Further, the workshop will only recommend necessary repairs or replacements and avoid overcharging you for non-essential auto services.
  • Optimal driving experience: A regularly-serviced Mercedes-Benz provides a great driving experience. Minor issues are quickly resolved, and unexpected road situations can be avoided.
  • Authorised servicing: Contracting an independent car workshop for your Mercedes-Benz will guarantee your vehicle will be in the right hands.


Authorised servicing centres in Singapore have the latest diagnostic tools, OEM parts, industry-standard procedures, and technicians working on the car. You won’t get these from a run-of-the-mill workshop.

Although it isn’t the first automaker to do so, Mercedes-Benz’s software-based maintenance reminder system remains invaluable for every car owner. It’s a one-of-a-kind feature in the automotive industry, especially for later models.


With this diagnostic system, Mercedes-Benz owners are given complete peace of mind as they drive the car in their lifetime. 


Vehicles go through normal wear and tear, but the built-in scheduling system informs car owners of parts that need repair or replacement, allowing them to stay on top of their maintenance.

Is It Expensive To Maintain A Mercedes In Singapore?

Genuine Mercedes servicing is reliable, but it does not come cheap. Spare OEM parts can be difficult to find, as you would experience for other luxury vehicle brands. This is why you should only bring your Mercedes-Benz to an authorised auto shop that knows which repairs/replacements to carry out.

How Often Should You Service A Mercedes-Benz?

As a rule of thumb, you should service your Mercedes-Benz every 15,000 km or after one year of car ownership (whichever comes first). Consult the vehicle manufacturer manual or an auto service centre for more information.

How Will I Know When My Mercedes Needs To Be Serviced?

Look on the dashboard instrument panel of your Mercedes-Benz car and click on the ASSYST PLUS feature. Your car will inform you of how many kilometres are left before it’s due for either Service A or B.
