Solution
1. Preparation
  • Gather tools and materials needed for the repair.
  • Tools required: OBD-II scanner, socket set, torque wrench, oil pressure gauge, shop towels.
  • Safety warnings: Allow the engine to cool before starting any work. Disconnect the battery for electrical safety.
2. Clear Error Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Follow the scanner's instructions to read and clear any error codes.
  • Disconnect the scanner after clearing the codes.
3. Inspect Oil Filter and Drain Plug
  • Raise the vehicle safely using jack stands.
  • Inspect the oil filter for proper installation. Tighten if loose, but ensure it is not overtightened.
  • Check the drain plug under the oil pan for leaks and ensure it is properly torqued (usually around 20-25 Nm).
4. Oil Level and Quality Check
  • Remove the dipstick and wipe it clean. Reinsert and pull it out to check the oil level.
  • If low, add the correct oil type and viscosity as per the owner's manual.
  • If the oil appears dirty or contaminated, consider a complete oil change.
5. Verify Engine Function
  • Start the engine and monitor for any unusual noises or vibrations.
  • Observe the oil pressure gauge to ensure it reads within normal limits.
  • If the problem persists, further diagnostics may be needed for potential internal issues.
