Understanding BMW's Maintenance System

The 2015 BMW 328d xDrive operates on a Condition Based Service (CBS) system. Sensors and special algorithms take the driving conditions of your vehicle into account to recognize 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 is stored in the remote control, and your service center will read this data to suggest the right array of service procedures for your vehicle . For major periodic service, this should generally be done every 2 years or after 30,000 kilometres .

Important Storage Note: Storage periods during which the vehicle battery was disconnected are not taken into account by the CBS system. 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 microfilter .

For the definitive maintenance schedule for your specific vehicle, consult the Service and Warranty Information Booklet for US models or the Warranty and Service Guide Booklet for Canadian models .

Engine Oil Service

Oil Specifications and Capacity

The 2015 BMW 328d xDrive N47 diesel engine requires BMW-approved synthetic oil. The engine oil capacity is 5.5 quarts . Oils meeting BMW Longlife-04 approval and API SN standards are required .

Key Specifications:

* Viscosity: 5W-30

* Approval: BMW LL-04

* Type: Full synthetic

Oil Change Interval

Specialist Guidance: Motor oil is the single most important element in keeping your engine healthy and helping it to enjoy a long life . Pelican Parts recommends changing synthetic motor oil every 5,000 miles and always replacing the filter when changing the oil . The CBS system may allow for longer intervals, but a 5,000-mile interval is a common conservative approach for the N47 diesel engine.

Diesel Fuel Filter Service

The high-pressure common-rail fuel system on the N47 diesel engine is sensitive to fuel contamination. A clogged fuel filter can result in difficulty starting, hesitation upon accelerating, decreased fuel economy, and rough idling .

Recommended Interval: The fuel filter should be replaced every 30,000 to 40,000 miles .

Replacement Information:

* Replacement Part: BMW part number 13328572522

* Cost Estimate: The estimated cost for fuel filter replacement on a 2015 BMW 328d xDrive ranges from approximately $505 to $633

Brake Fluid Service

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

Service Rationale: Brake fluid absorbs moisture over time. Contaminated brake fluid can appear black or brown and cause a spongy brake pedal feel . A brake system flush removes the existing fluid and moisture from the system and replaces it with new, clean fluid . The estimated cost for a brake system flush ranges from approximately $198 to $262 .

Steering and Suspension Lubrication

Proper lubrication is required to keep the steering and suspension systems operating smoothly . Each vehicle will have its own quirks and issues in the steering and suspension, and some parts are permanently lubricated and sealed from the factory .

Service Details: Apply grease to the zerk fittings of all the steering and suspension parts .

Symptoms Indicating Service is Needed:

* Squeaking noise when turning or going over bumps

* Groaning sound when turning

* Suspension is bumpy and doesn't work smoothly

Cost Estimate: The estimated cost for lubricating the steering and suspension on a 2015 BMW 328d xDrive ranges from approximately $114 to $146 .

Power Steering Fluid Service

Power steering fluid flows through the power steering hydraulic system, decreasing the effort needed by the driver to turn the steering wheel . As components in the steering system wear, metal particles will contaminate the fluid, causing seals to leak and components to fail .

Recommended Interval: Consider getting a power steering flush once every 3-4 years .

Symptoms Indicating Service is Needed:

* Groaning noise from the power steering pump or steering gear

* Difficulty in turning the steering wheel

* Contaminated fluid (brown/black)

Cost Estimate: The estimated cost for a power steering fluid service on a 2015 BMW 328d xDrive ranges from approximately $234 to $405 .

Oil Filter Housing Gasket

Known Issue: Oil filter housing leaks are a fairly common problem on the BMW N47 and N57 diesel engines . A complete set of gaskets is available to reseal the oil filter housing, engine oil cooler, and transmission oil heat exchanger assembly .
