Why does my Audi A2's engine misfire at idle and low speeds?

I have noticed that my Audi A2's engine starts to misfire at idle and low speeds. It is fine at higher speeds. What could be causing this issue?

The most common cause for engine misfires at idle and low speeds is a faulty ignition coil or spark plugs. These should be checked and replaced if necessary.

Another potential cause could be a clogged fuel filter or a dirty mass air flow sensor. Both of these can contribute to a rough idle and low speed misfires.
