Why Brake Fluid Service Matters
Brake fluid is a hydraulic fluid specially formulated to withstand the extreme pressures and temperatures of your braking system. Brake fluid should be changed every time you service your brakes. Different brake systems require different brake fluid formulations; check your owner's manual for your vehicle's particular specifications .
Spark Plug Service
Specifications
The 2017 BMW 430i xDrive Coupe uses OEM spark plugs from NGK , Bosch , and Champion as original equipment.
Why Spark Plug Service Matters
Spark plugs are used to ignite the fuel-air mixture in the engine's combustion chamber . Keeping your spark plugs fresh is a very important part of keeping your car in top shape .
Spark Plug Inspection: Check for abnormal pitting or charred plug ends when replacing plugs. Also check each plug against each other—any strange variations among plugs may indicate an issue with a particular cylinder .
Additional Service Items
Wheel Bearings
As part of routine basic maintenance, it is a good idea to clean and repack your wheel bearings once a year to ensure they are properly lubricated . Genuine BMW wheel bearing grease is recommended for high temperature service in rolling bearings .
Engine Air Filter
BMW recommends replacing the engine air filter at regular intervals as part of routine maintenance. A clean air filter ensures optimal airflow to the engine, supporting combustion efficiency and turbocharger health.
Cabin Microfilter
The cabin microfilter should be replaced every 2 years to maintain interior air quality and HVAC system efficiency.
Coolant Service
Coolant replacement generally occurs every 4 years or 60,000 miles. This service prevents overheating and maintains engine temperature.
Transmission Fluid
BMW generally designates the automatic transmission fluid as "lifetime fill" for normal operation. However, the transmission is one of the most neglected service areas on a car.
