BMW 328i Sedan 3 Series 2010 Owner's Manual

The recommended oil type is BMW High Performance Synthetic Oil SAE 5W-30. Alternatively, any synthetic oil that meets BMW Longlife-01 specifications can be used.
The oil should be changed every 10,000 miles or 12 months, whichever comes first. However, it's best to check the vehicle's service indicator and consult your owner's manual for specific recommendations.
Common causes include issues with the oxygen sensor, catalytic converter, mass airflow sensor, and loose gas cap. It's advisable to have a diagnostic test run to pinpoint the exact issue.
To reset the TPMS, turn the ignition to the "on" position without starting the engine, press the TPMS reset button located under the steering wheel until the TPMS indicator on the dashboard blinks three times, and then drive the car for about 20 minutes for the system to recalibrate.
The recommended tire pressure is typically 32 PSI for the front tires and 35 PSI for the rear tires, but you should verify this information on the sticker located on the driver's side door jamb.
Improving fuel efficiency can be achieved by maintaining proper tire pressure, ensuring regular engine maintenance, using high-quality fuel, reducing excess weight in the car, and avoiding aggressive driving habits.
Common issues include leaks from the water pump or radiator, and failure of the thermostat. Regular inspection and timely replacement of these components can help prevent overheating.
To replace the air filter, locate the air filter housing in the engine compartment, unclip the cover, remove the old filter, and insert a new one before reattaching the cover. Ensure the new filter is seated properly.
Signs include difficulty starting the engine, dimming headlights, and electrical issues. If the battery is over 4 years old, it's a good idea to have it tested.
Brake fluid should be replaced every 2 years. This is crucial for maintaining effective braking performance and preventing moisture buildup in the brake system.
