It is recommended to replace the spark plugs in your Audi A2 every 30,000 miles or 3-4 years. This will ensure that your car runs smoothly and efficiently.

If you notice a decrease in performance or a rough idle, it is possible that your spark plugs need to be replaced. Keep an eye out for these signs and replace them promptly to avoid further damage.

Regular maintenance is key to keeping your Audi A2 in top shape. Make sure to schedule tune-ups and replacement of parts, such as spark plugs, according to the manufacturer's recommendations.
