Why Does My Audi A5's Engine Struggle to Start?

My Audi A5's engine seems to struggle when starting up. It takes a few tries and sometimes makes strange noises. What could be causing this issue?

There could be a variety of reasons for this issue. One possible cause could be a weak battery. Over time, car batteries can lose their charge and may need to be replaced. Another possibility is a faulty starter motor. If the starter is not functioning properly, it can cause the engine to struggle when starting up. Additionally, dirty or corroded spark plugs can also cause starting issues. It may be a good idea to have a professional check these components to determine the cause of the problem.
