• Diesel fuel filter replacement is recommended every 30,000 to 40,000 miles to protect the high-pressure fuel system .
• Brake fluid replacement is recommended every two years .
• The original 48-month/50,000-mile maintenance program for the 2015 BMW 328d has long since expired for this model year .

Understanding BMW's Condition Based Service (CBS) System

The 2015 BMW 328d is equipped with the Condition Based Service (CBS) system . Unlike conventional systems that rely solely on distance traveled, this intelligent system uses sensors and special algorithms that take the different driving conditions of your BMW into account to determine current and future service requirements .

How CBS Works

Sensors and special algorithms take into account the driving conditions of your vehicle. Based on this, Condition Based Service recognizes the maintenance requirements . The system makes it possible to adapt the amount of maintenance corresponding to your user profile . Detailed information on service requirements can be displayed on the Control Display .

Service Data in the Remote Control

Information on the required maintenance is continuously stored in the remote control . Your service center will read out this data and suggest the right array of service procedures for your vehicle. Therefore, hand your service specialist the remote control with which the vehicle was driven most recently .

Storage Periods

Storage periods during which the vehicle battery was disconnected are not taken into account . If this occurs, have a service center update the time-dependent maintenance procedures, such as checking brake fluid and, if needed, changing the engine oil and the microfilter/activated-charcoal filter .

Service and Warranty Documentation

For additional information on service requirements, consult your Service and Warranty Information Booklet for US models and Warranty and Service Guide Booklet for Canadian models . Make sure to have regular maintenance procedures recorded in the vehicle's Service and Warranty Information Booklet; these entries are proof of regular maintenance .

Major Periodic Service

For major periodic service, this should generally be done every 2 years or after 30,000 kilometers (approximately 18,600 miles) .

Engine Oil Service

Oil Specifications

The 2015 BMW 328d requires BMW-approved low-SAPS (sulfated ash, phosphorus, sulfur) synthetic oil due to the diesel particulate filter. The engine uses BMW Longlife-04 approved oil .

Oil Details:

• Viscosity: 5W-30
• Approval: BMW Longlife-04
• Type: Low-SAPS full synthetic
• Capacity: Approximately 5.5 quarts
• Specifications: API SN, BMW Longlife 04

BMW Genuine Twin Power Turbo 5W-30 is the factory-recommended oil, meeting the Longlife 04 specification .

Oil Change Interval

BMW recommends oil changes every 10,000 to 15,000 miles, as determined by the CBS system . The engine oil capacity is 5.5 quarts . Products such as Liqui Moly Top Tec 4600 SAE 5W-30 allow for oil change intervals of up to 40,000 km, depending on the manufacturer's specifications .

Key Considerations for Diesel Engines

• Diesel engines place greater thermal stress on oil than gasoline engines
• The N47 engine is sensitive to oil quality; using the correct BMW LL-04 specification is essential
• Low-SAPS oil is required to prevent clogging of the diesel particulate filter (DPF)

Diesel Fuel Filter Service

Recommended Interval: Replace the diesel fuel filter every 30,000 to 40,000 miles .

Service Rationale: The high-pressure common-rail fuel system on the N47 diesel engine is sensitive to fuel contamination. A clogged fuel filter can restrict fuel flow, cause starting issues, reduce performance, and potentially damage expensive fuel system components such as the high-pressure pump and injectors . The replacement procedure is very straightforward .

Replacement Part: The fuel filter for the 2015 BMW 328d is listed by BMW as part number 13328572522 . Meyle offers an OEM-quality replacement fuel filter for F30/F31 328d models with rear-wheel drive or xDrive for model years 2014-2018 .

Brake Fluid Service

Recommended Interval: It is recommended to change the brake fluid every two years .

Service Rationale: Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. Moisture in the brake system can corrode internal components and lower the fluid's boiling point, leading to brake fade. Regular replacement is critical for maintaining braking performance.

Additional Maintenance Considerations

Drivetrain Fluid Service (xDrive Models)

The 2015 BMW 328d xDrive models feature BMW's xDrive all-wheel-drive system, which includes a transfer case and front and rear differentials that require periodic fluid changes. The Bentley BMW 3 Series Service Manual covers xDrive transfer case fluid service and ATF service . Specialists recommend servicing these components at regular intervals to ensure the longevity of the all-wheel-drive system.

Bentley Service Manual

The BMW 3 Series (F30, F31, F34) Service Manual: 2012-2015 contains in-depth maintenance, service and repair information for the BMW 3 Series from 2012 to 2015 . It covers the N47 diesel engine in the 328d, including xDrive models . The manual includes:

• General data and maintenance
• Diesel fuel injection system diagrams and explanations for turbo-direct injection (TDI) engine management systems
• Front axle differential service
• Cooling system, thermostat and radiator service
• Brakes, steering and ABS troubleshooting and repair
• Comprehensive wiring schematics

The do-it-yourself BMW owner will find this manual indispensable as a source of detailed maintenance and repair information .
