Why is my Audi A1's engine making a loud tapping noise?

I've noticed that my Audi A1's engine has been making a loud tapping noise whenever I start the car or accelerate. It didn't use to make this noise before and I'm worried it might be a sign of a bigger issue. Is this something I should be concerned about?

It's possible that the tapping noise is coming from a faulty valve or a worn out camshaft. It's best to have it checked by a mechanic to determine the exact cause.

Another potential cause could be low oil levels. Make sure to regularly check and top up your oil to avoid any potential engine issues.

I had a similar issue with my Audi A1 and it turned out to be a loose spark plug. You might want to have that checked as well.
