Why does my Audi A4 seem to have a rough idle?

I recently noticed that my Audi A4 has a rough idle when I come to a stop. It's not super noticeable, but I can definitely feel it. Any idea what might be causing this issue?

Hi Samantha, rough idle can be caused by a variety of issues, but one common cause in Audi A4s is a dirty or faulty mass airflow sensor. I would suggest having this component checked and cleaned or replaced if necessary.

Hi Samantha, another possible cause of rough idle in an Audi A4 could be a worn spark plug or spark plug wire. It's important to regularly replace these components to ensure proper engine performance.
