Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Allow the engine to cool before starting work.
Disconnect the battery to prevent electrical issues.

2. Check Oil Level

Remove the dipstick, wipe it clean, and reinsert it fully.
Pull the dipstick out again and check the oil level; it should be between the minimum and maximum marks.
If low, proceed to add oil.

3. Add Engine Oil

Select the correct oil type as per the owner’s manual (typically, BMW recommends synthetic oil).
Using a funnel, add oil gradually until the correct level is reached.
Reinsert the dipstick to check the level after adding oil.

4. Inspect for Leaks

Visually check around the oil pan, drain plug, and oil filter for any signs of leaks.
If a leak is found, identify the source and replace the faulty seal or component.

5. Change Engine Oil (if necessary)

Drain the old oil using the drain plug (ensure the oil is warm for better flow).
Replace the oil filter with a new one.
Refill with fresh engine oil to the correct level.

6. Reset Oil Change Light

Turn on the ignition without starting the engine.
Use the vehicle’s onboard computer to navigate to the service menu.
Reset the oil change indicator to ensure accurate tracking.
