why does my Volvo XC60 engine light come on after oil change

Solution

1. Preparation

• Gather tools including an OBD-II scanner, socket set, and oil filter wrench.
• Ensure the vehicle is parked on a level surface and the engine is turned off and cool.
• Disconnect the battery negative terminal for safety.

2. Retrieve and Analyze Trouble Codes

• Use the OBD-II scanner to read the engine codes.
• Document any codes that appear for further analysis.
• Clear the codes and see if they return after restarting the engine.

3. Correct Oil Level and Quality

• Check the oil dipstick to confirm the oil level is within the acceptable range.
• If low, add the manufacturer-recommended oil type until it reaches the correct level.
• If oil appears dirty or contaminated, a full oil change may be necessary.

4. Inspect Oil Filter

• Use an oil filter wrench to remove the oil filter.
• Check the rubber O-ring on the new filter for proper installation.
• Install a new oil filter, ensuring it's tightened properly but not over-torqued (hand-tight is usually sufficient).

5. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the vehicle and monitor for any warning lights.
• Conduct a short test drive to ensure the light does not reappear and the engine operates smoothly.
