Mercedes-Benz vehicles use a service code system to inform owners about upcoming maintenance needs. If you’re a Mercedes-Benz owner, you might encounter codes like “Service A,” “Service B,” and others. One such code that might appear is “Service BH.” This article will delve into what “Service BH” likely means, based on real-world owner experiences and how to interpret Mercedes-Benz service indicators.
Understanding Mercedes-Benz Service Codes
Mercedes-Benz utilizes the ASSYST PLUS system to monitor your vehicle’s condition and schedule necessary maintenance. These services are often indicated by letters (like A, B, C, etc.) combined with additional numbers or letters, which can sometimes cause confusion. Owners often turn to online forums and communities to decipher these codes when the official documentation isn’t immediately clear or accessible.
Decoding Service BH Based on Owner Experience
One Mercedes-Benz owner with a C300 4matic, having clocked over 155,000 miles, encountered the “Service BH” notification. Based on their research and analysis of the ASSYST PLUS menu, they deduced that “Service BH” isn’t a standard service code in itself, but rather a combination of specific service items due at that mileage.

Accessing Your ASSYST PLUS Menu
To understand what specific services are included in your “Service BH” notification, you can access the ASSYST PLUS menu in your Mercedes-Benz. The process generally involves using the steering wheel controls and the instrument cluster display.

Deciphering Service Numbers for Service BH
Based on the owner’s findings, “Service BH” likely corresponds to a combination of Service B tasks along with mileage-based maintenance. Specifically, service numbers 2, 3, 11, and 13 were identified. These numbers, when cross-referenced with a general Mercedes-Benz service schedule, point to:
- Service B: This is a comprehensive service that typically includes an engine oil and filter change, fluid level checks, brake component inspection, and a general inspection of various vehicle systems.
- Fuel Filter Replacement: Mercedes-Benz maintenance schedules often recommend fuel filter replacement around the 150,000-mile mark or every 15 years.
- Coolant Change: Coolant replacement is also a mileage-based service, often recommended around the same interval as the fuel filter.

Therefore, “Service BH” in this context appears to be Service B combined with the scheduled fuel filter and coolant replacement due around 150,000 miles.
Confirming Service Needs and Maintenance Schedules
While the ASSYST PLUS menu and owner experiences provide valuable insights, always refer to your Mercedes-Benz owner’s manual and the official maintenance schedule for your specific model and year. This documentation will offer the most accurate and detailed information about required services based on mileage and time intervals.
