The number “1” indicates that it is the first occurrence of the Mercedes Benz B Service, as there may be subsequent B services (such as Mercedes Service B2, B3,… Mercedes B5 Service, and Mercedes B9 Service) at different intervals.

During the B1 service, a combination of inspections, fluid replacements, and component checks is typically performed. The B1 service is essential to ensure the longevity, reliability, and performance of your Mercedes-Benz.

Checklist of Tasks Performed for the Mercedes B1 Service

1. Oil and Filter Change

One of the key routine maintenance tasks performed during Service B1 is an oil and filter change. This involves draining the old engine oil and replacing it with fresh oil, along with replacing the oil filter. Regular oil changes help lubricate the engine, reduce friction, and prevent engine damage.

2. Brake System Inspection

The brake system is essential for your safety, so, during Service B1, a thorough inspection of the braking components is conducted. This includes checking the brake pads, rotors, calipers, and brake fluid levels. 

Any signs of wear, damage, or brake fluid contamination are addressed to ensure optimal braking performance.

2. Fluid Level Checks

Routine maintenance includes checking and topping up various fluid levels in your vehicle. This includes coolant, power steering fluid, brake fluid, and windshield washer fluid. 

Proper fluid levels are vital for the efficient operation of these systems and to prevent overheating, steering issues, brake problems, and poor visibility.

3. Tire Inspection and Rotation

Your tires play a crucial role in your vehicle’s performance and safety. During Service B1, the tires are inspected for tread wear, damage, and proper inflation. Additionally, tire rotation may be performed to ensure even tire wear and extend the lifespan of the tires.

4. Electrical System Check
