Why does my Audi A1's engine make clicking noises after starting?

I recently purchased a used Audi A1 and noticed that the engine makes clicking noises for a couple of seconds after starting. It has low mileage and has been regularly maintained, so I'm worried if this is a sign of a bigger problem.

The clicking noise could be caused by low oil levels or a weak battery. It's important to regularly check your oil levels and replace the battery if needed. If the problem persists, have a mechanic inspect the engine for any potential issues.
