The recommended replacement interval for the cam belt on an Audi A4 1.8T engine is every 60,000 miles. However, some mechanics recommend replacing the belt earlier, at around 40,000 miles, due to the importance of the belt in preventing engine damage.
It is important to note that the cam belt is a critical component of the engine, and if it fails, it can cause significant damage to the engine. Therefore, it is important to replace the cam belt according to the recommended schedule, or sooner if you experience any symptoms of cam belt wear or damage.
