Why does my Audi A4 have difficulty starting?

I have recently noticed that my Audi A4 has been experiencing difficulty starting. It takes several tries for the engine to turn over and start. What could be causing this and what steps can I take to fix it?

It is possible that your spark plugs are worn out and need to be replaced. This can cause difficulty starting the engine. I suggest taking your car to a mechanic to get them checked and replaced if necessary.
