Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool and parked on a level surface.
Disconnect the battery to prevent electrical shorts.

2. Check and Top Off Oil Level

Remove the dipstick and clean it with a lint-free cloth.
Reinsert the dipstick, remove it again, and check the oil level.
If low, add the recommended oil type (e.g., BMW Longlife-01 or Longlife-14).
Check for leaks after adding oil.

3. Replace Oil Filter

Locate the oil filter and remove it using an oil filter wrench.
Apply a small amount of new oil to the rubber gasket of the new filter.
Install the new oil filter, hand-tightening it securely.
Ensure the filter is properly seated to prevent leaks.

4. Inspect and Replace Oil Pump (if necessary)

Drain the engine oil by removing the oil drain plug and allowing it to fully empty.
Remove the oil pan by unbolting it and gently prying it off.
Locate the oil pump and check for wear or damage.
If defective, remove the old oil pump and install a new one, ensuring all gaskets are replaced.

5. Refill Engine Oil

Reinstall the oil drain plug with a torque of 25 Nm (18.4 lb-ft).
Pour in the recommended amount of new engine oil through the oil filler cap.
Start the engine and let it idle for a few minutes, checking for leaks.
