What is the lifespan of an Audi A3's timing belt?

I am planning on purchasing a used Audi A3 and I am wondering about the lifespan of its timing belt. How often does it need to be replaced and what are some signs that it needs to be changed? I want to make sure I am not in for any unexpected maintenance costs.

The lifespan of an Audi A3's timing belt varies depending on the model and year, but it typically needs to be replaced every 80,000-100,000 miles. However, it is always best to consult your owner's manual for specific maintenance guidelines.

One of the main signs that your Audi A3's timing belt needs to be replaced is if you hear a squeaking or grinding noise coming from the engine. It's also important to keep an eye on your mileage and follow the recommended replacement interval to prevent any serious engine damage. Don't wait until it breaks, as it can leave you stranded and cause more expensive repairs.
