Why does my Audi A1 make a loud rattling noise when accelerating?

I recently noticed that my Audi A1 starts making a loud rattling noise whenever I accelerate, especially while driving uphill. It seems to be getting worse over time. What could be causing this issue?

It's possible that your timing chain may be worn or damaged, causing the rattling noise. It's best to have it checked by a certified mechanic as soon as possible to avoid any further damage to your engine.
