Why does my Audi A2's engine have trouble starting in cold weather?

I recently bought a used Audi A2 and I've noticed that whenever the temperature drops, the engine has a hard time starting. What could be the cause of this issue and how can I prevent it?

It is possible that your car's battery is starting to lose its charge in cold weather, causing the engine to have difficulty starting. One way to prevent this is to have your battery checked and replace it if necessary before the winter season.

Another reason for difficulty starting in cold weather could be due to old or worn out spark plugs. It's recommended to have your spark plugs replaced every 30,000 miles or so to ensure smooth starting and running of your engine in all weather conditions.
