Solution

1. Preparation

Tools Required: Lint-free cloth or paper towel.
Safety Warnings: Ensure the engine is cool to avoid burns.

2. Check Oil Level

Wipe Dipstick: Use a lint-free cloth to clean the dipstick.
Insert Dipstick: Push the dipstick back into its tube fully to ensure an accurate reading.
Remove Dipstick: Pull it out again and look at the oil level indicated on the dipstick.
Evaluate Oil Level: The oil level should be between the "MIN" and "MAX" marks on the dipstick. If it is below the "MIN" mark, oil needs to be added.

3. Adding Oil (if necessary)

Select Correct Oil: Ensure that the engine oil meets BMW specifications (typically BMW Longlife-04).
Add Oil: Using a funnel, pour oil into the oil fill cap, located on top of the engine. Add in small increments, checking the level on the dipstick after each addition.
Recheck Oil Level: After adding oil, reinsert the dipstick and remove it again to ensure the level is now within the acceptable range.
