Why is my Audi A3's engine making a tapping noise?

I've noticed that my Audi A3's engine has been making a tapping noise when I start it up in the morning. I'm worried that there may be something wrong with my engine. What could be causing this noise and how can I fix it?

It is possible that there is an issue with your engine's hydraulic lifters. These lifters can become dirty or clogged over time, which can lead to the tapping noise you are hearing. I recommend taking your car to a mechanic who specializes in Audis to have them inspect and potentially clean or replace the lifters.

Another possibility is that your engine's oil is low or dirty. Low oil levels can cause the engine to make strange noises, including tapping. Check your oil level and consider getting an oil change if it's been awhile since your last one.

One more thing to check is your spark plugs. If they are worn out or dirty, they can cause the engine to make a tapping noise. Have them inspected and replaced if needed.
