Is it necessary to regularly change the spark plugs in an Audi A1?

I've been noticing some misfiring in my Audi A1 and I'm wondering if it's due to old spark plugs. How often should I replace them and what signs should I look out for?

Yes, it is recommended to change your spark plugs every 30,000 miles or every 3-5 years. Signs that your spark plugs may need to be replaced include difficulty starting your car, a decrease in fuel efficiency, and rough idling.

I've had the same issue with my Audi A1 and changing the spark plugs made a noticeable difference. It's worth doing as part of regular maintenance to keep your car running smoothly.
