How do I know when my Audi needs its timing belt replaced?

I am unsure when my Audi's timing belt should be replaced. How can I tell if it needs to be changed? Can I replace it myself or should I take it to a mechanic?

To determine if your Audi's timing belt needs to be replaced, look at the manufacturer's recommended maintenance schedule. Typically, a timing belt should be replaced every 60,000-100,000 miles. If you are nearing this mileage, it may be time to schedule a replacement. As for whether or not you can replace it yourself, it's always best to leave the job to a trained mechanic to ensure it is done correctly and safely.
