Why does my Audi A3 have a rough idle at low speeds?

I've noticed that my Audi A3 tends to have a rough idle when I'm driving at low speeds (around 15-25 mph). What could be causing this and how can I fix it?

One possible reason for your rough idle could be a dirty mass airflow sensor. Try cleaning it with a specialized cleaner to see if that improves your idle.

Another common issue that can cause rough idling is a faulty spark plug or ignition coil. It's important to have these components checked and replaced if necessary to ensure smooth driving.
