Why does my Audi 80 make a tapping noise when accelerating?

I have a 2003 Audi 80 and whenever I accelerate, there is a noticeable tapping noise coming from the engine. It doesn't seem to affect the performance of the car, but I'm worried it could be a sign of a larger problem. Has anyone else experienced this issue with their Audi 80?

The tapping noise is most likely caused by a faulty lifter or valve in the engine. It's important to get this checked out by a mechanic as soon as possible, as it could lead to more serious engine issues down the line.
