Solution

1. Preparation

Gather necessary tools such as an oil filter wrench, socket set, and oil catch pan.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check Owner's Manual

Locate the recommended oil change interval in the manual, typically every 10,000 to 15,000 miles or every 12 months, depending on driving conditions.
Confirm if the vehicle is equipped with the BMW Maintenance Program, which may affect intervals.

3. Perform Oil Change

Drain Old Oil:
1. Remove the oil drain plug with a socket wrench and allow the old oil to fully drain into the catch pan.
2. Replace the drain plug and tighten to the manufacturer’s specifications (usually around 25 Nm).
Replace Oil Filter:
1. Use an oil filter wrench to remove the old oil filter.
2. Lubricate the rubber gasket of the new filter with a bit of new oil and install it.
Add New Oil:
1. Open the oil filler cap located on the engine.
2. Pour in the recommended type and amount of engine oil (typically 5W-30 or 0W-30 synthetic).
3. Replace the oil filler cap securely.

4. Reset Service Light

Using the vehicle's onboard computer, navigate to the service menu to reset the oil change interval reminder.
