Why does my Audi A5's engine make a loud ticking noise?

I recently bought a used Audi A5 and noticed that the engine makes a loud ticking noise. Is this something I should be concerned about? What could be causing it?

The loud ticking noise in your Audi A5 could be caused by a number of factors, such as low oil levels, worn out camshaft lifters or even a faulty valve. It's important to get it checked by a professional mechanic as soon as possible to prevent any potential damage to your engine.

I had a similar issue with my Audi A5 and it turned out to be a faulty oil filter. Replacing it solved the problem for me. However, it's always best to get it checked by a mechanic to be sure of the exact cause and avoid any potential issues in the future.
