What can cause rough idling in an Audi A2?

I've noticed that my Audi A2 has been idling roughly. What could be causing this and what steps can I take to fix it?

There are several potential causes for rough idling in an Audi A2. One common cause is a dirty or clogged air filter. You should check and replace your air filter if necessary. Another possibility is a malfunctioning fuel pump, which can cause inconsistent fuel delivery to the engine. You may also want to check your spark plugs and ignition coils, as they can become worn or damaged over time. Lastly, it's always a good idea to keep up with regular maintenance, such as oil changes and tune-ups, to prevent any potential issues.
