Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, oil filter wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Check Oil Level and Quality

Reconnect the battery and start the engine.
Allow it to run for a minute, then shut it off.
Wait a few minutes and check the oil level using the dipstick.
If the oil level is low, add the appropriate type of oil as per the owner’s manual.

3. Inspect Oil Filter

Use an oil filter wrench to remove the oil filter if it was not installed correctly.
Check the rubber O-ring on the old filter and ensure it came off with the filter.
Install a new oil filter, ensuring it is properly seated and tightened to manufacturer's specifications (typically hand-tight).

4. Tighten Oil Drain Plug

Check if the oil drain plug is properly tightened.
Use a torque wrench to secure it to the manufacturer's specified torque (usually around 25 Nm, but verify with the service manual).

5. Clear Error Codes

Use the OBD-II scanner to clear any error codes that were triggered.
After clearing, monitor for any reoccurrence of the engine light.
