Why doesn't my Audi A2 start in cold temperatures?

I recently bought an Audi A2 and I've noticed that it has trouble starting in cold weather. The engine turns over, but it takes longer than normal to start. What could be causing this issue?

It's likely that your spark plugs are worn out and need to be replaced. This can cause difficulty starting in cold temperatures. I suggest getting them checked by a mechanic and replaced if necessary.

Low battery voltage can also be a culprit. As temperatures drop, the battery becomes less effective and may not have enough power to start the engine. Consider getting a jumpstart or replacing your battery.

Another possibility is that your fuel lines are frozen. Make sure to use a winter-grade fuel and consider adding a fuel de-icer to your tank to prevent this issue.
