How do I know when to replace my Audi A8's spark plugs?

I have a 2019 Audi A8 and I'm not sure when I should replace the spark plugs. How do I know when it's time for a replacement?

It is recommended to replace your spark plugs every 30,000 miles or every 3 years, whichever comes first. However, if you notice any of the following symptoms, it's best to replace them as soon as possible: difficulty starting your car, decreased fuel efficiency, engine misfires, or rough idling.

You can also refer to your Audi A8's owner's manual for specific maintenance schedules and recommendations. It's important to keep up with regular spark plug replacements to ensure your engine is running smoothly and efficiently.

If you're experiencing any of the mentioned symptoms or if it's been over 30,000 miles since your last spark plug replacement, it's definitely time to schedule a service appointment. Don't wait too long, as worn out spark plugs can cause damage to other engine components.
