Why is my Audi A1 making a ticking noise when I accelerate?

I recently noticed a faint ticking noise coming from my Audi A1 whenever I accelerate, but it seems to go away once I reach a certain speed. What could be causing this noise and should I be concerned?

The most likely cause of this ticking noise is a faulty lifter in your engine. It's important to have this checked and replaced if necessary, as it could lead to more serious engine issues down the line.
