Why does my Audi R8 produce a loud noise when starting the engine?

Whenever I start my Audi R8, there is a very loud noise coming from the engine. It doesn't happen all the time, but it's becoming more frequent. What could be causing this and how can I fix it?

That loud noise could be a result of a faulty spark plug or a worn out timing belt. I recommend bringing your car to a certified mechanic for a proper diagnosis and repair.

It's possible that there is an issue with your fuel injectors or exhaust system. I would suggest having a professional check these components to determine the root cause of the noise.
