It is recommended to change the spark plugs every 60,000 miles for optimal engine performance in the 2002 BMW 325Ci.
To replace the headlight bulb, open the hood and locate the back of the headlight assembly. Remove the cover, disconnect the electrical connector, and release the bulb's retaining clip. Replace with a new bulb and reassemble.
The recommended tire pressure is typically 32 PSI for the front tires and 36 PSI for the rear tires. Always check the owner's manual or the sticker on the driver’s door jamb for precise specifications.
To improve fuel efficiency, ensure regular maintenance, including air filter and oil changes. Maintain proper tire pressure, avoid excessive idling, and drive smoothly by avoiding rapid acceleration and deceleration.
Common causes of a rough idle include vacuum leaks, faulty spark plugs, dirty fuel injectors, or a malfunctioning idle control valve. Inspect and address these issues to resolve the problem.
To replace the cabin air filter, open the hood and locate the cabin air filter housing near the windshield. Remove the cover, take out the old filter, and insert a new one. Ensure the filter is seated properly before replacing the cover.
