1. What Are Mercedes Benz Workshop Codes?

Mercedes Benz workshop codes are alphanumeric codes used to identify the specific maintenance tasks required for a Mercedes-Benz vehicle during a service. These codes, part of the ASSYST Plus service system, indicate which service items need attention, such as oil changes, brake fluid replacements, or filter checks. Understanding these codes ensures that your Mercedes receives the precise care it needs, optimizing its performance and longevity.

1.1. The Evolution of Mercedes Benz Service Systems

Initially, Mercedes-Benz used a simple system with ‘A’ and ‘B’ services. An ‘A’ service was a minor service, primarily involving an engine oil and filter change, along with a minor vehicle inspection. The ‘B’ service, on the other hand, was a major service that included an engine oil and filter change, pollen filter replacement, and a major vehicle inspection.

1.1.1. Additional Service Items

Alongside these ‘A’ and ‘B’ services, there were additional service items based on the vehicle’s age or mileage. These included:

• Air filter replacement
• Fuel filter replacement
• Brake fluid change
• Coolant change
• Spark plug replacement
• Gearbox oil/filter change

1.2. Introduction of ASSYST Plus

The service system evolved into ‘ASSYST Plus,’ which considered time and wear-specific maintenance items, along with any maintenance-relevant special equipment. This upgrade first appeared on the 211 E-Class, as well as the 251 R-Class, 164 ML-Class, and 169 A-Class models.

1.2.1. Lettered Services Beyond A and B

With ASSYST Plus, services were identified by letters up to ‘H,’ leading to A, B, C, D, E, F, G, or H service designations. This expansion aimed to provide more precise maintenance schedules tailored to the vehicle’s needs.

1.3. Integration of Numbers and Letters

To simplify the system and align with the Mercedes-Benz Digital Service Book (DSB) introduced around 2008, models like the 204 C-Class and 212 E-Class began using a combination of letters and numbers (or letters) after the ‘A’ or ‘B.’ This applied only when additional service items were due. Common combinations included A1, B1, A5, B5, A3, AK, AC, and B0.

1.4. Workshop Codes

Each service item is numbered with the letter and additional number/letter combination. You must navigate to the workshop menu on the instrument cluster to view the workshop code. On most vehicles equipped with a 12-button steering wheel, follow these steps to access the workshop menu:

1. Turn the ignition to position 1.
2. Ensure the overall mileage is displayed.
3. Press and hold the call answer button.
4. While holding the call answer button, press and hold the OK button.

1.4.1. Example Workshop Codes

For example, an ‘A’ service has a service code of ‘505,’ which corresponds to service item 1 (minor inspection) and service item 3 (engine oil and filter change).

Similarly, a ‘B1’ service has a service code of ‘E0E,’ which translates to service item 2 (major inspection), service item 3 (engine oil and filter change), and service item 4 (brake fluid change).

1.5. Key Service Items

From these examples, we can deduce the following:

• Service item 1 indicates an ‘A’ service.
• Service item 2 indicates a ‘B’ service.
• Service item 3, the engine oil and filter change, is required at every service.

1.5.1. Additional Service Items List

Here are some additional service items that may be encountered:

• Service 4 – Brake fluid change
• Service 5 – Combination filter (additional filter on some models)
• Service 8 – Air filter replacement (sometimes differential oil; check the service sheet)
• Service 10 – Sunroof guide rails clean/regrease
• Service 11 – Fuel filter replacement
• Service 12 – Replace spark plugs
• Service 13 – Engine coolant renewal
• Service 14 – Main coolant circuit (possibly cooling system for hybrids)
• Service 15 – Towing hitch lubrication
• Service 20 – Gearbox oil change/filter renewal
• Service 24 – Cambelt replacement/water pump replacement
