How can I replace the spark plugs in my Audi A2?

I have noticed that my Audi A2 has been running a little rough lately and I suspect it might be due to old spark plugs. Is this a task I can do myself or should I take it to a mechanic? What tools and steps do I need to take for a successful replacement?

Replacing spark plugs in an Audi A2 is a relatively simple task that you can do yourself. Just make sure to have the right spark plugs and a spark plug socket wrench on hand. Remove the old spark plugs carefully and gap the new ones according to manufacturer's instructions.
