why is my Skoda Octavia showing a "service now" message on the dashboard

Solution

1. Preparation

• Gather necessary tools and replacement parts.
• Disconnect the negative battery terminal to prevent electrical issues.
• Ensure the vehicle is on a flat surface and securely supported.

2. Perform Scheduled Maintenance

a. Engine Oil Change

• Remove the oil drain plug with a socket set.
• Allow the old oil to completely drain into a suitable container.
• Replace the oil filter using an oil filter wrench.
• Install a new oil filter and torque it to the manufacturer’s specifications (usually around 18-25 Nm).
• Reinstall the drain plug and torque it to the manufacturer’s specifications (usually around 30-40 Nm).
• Fill the engine with new oil according to the manufacturer's specifications (typically 5W-30 or 5W-40).

b. Other Fluid Checks and Changes

• Inspect and replace the air filter if necessary.
• Check and top off or replace brake fluid, coolant, and windshield washer fluid as required.

3. Reset Service Light

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to reset the service light.
• Follow the scanner's instructions to clear any stored error codes.
