What is the maintenance schedule for the Audi A4's timing belt?

I recently purchased a used Audi A4 and I am not sure when the timing belt should be replaced. Can you provide some helpful tips and advice on when it should be replaced and what steps to take?

The timing belt should be changed every 80,000-100,000 miles depending on your driving habits and the condition of the belt. I recommend getting it replaced as soon as possible if you are unsure when it was last changed.

When replacing the timing belt, it is also important to have the tensioner and water pump replaced as well to prevent any future issues. Don't wait too long to get these parts replaced as it can cause major damage if they fail.

It is always better to err on the side of caution when it comes to timing belt replacement. If you are unsure when it was last changed, have it replaced to avoid any potential problems.
