I have noticed that my Audi A3 has been idling rough lately. What could be causing this issue?
ReplyOne possible cause of a rough idle in an Audi A3 could be a dirty air filter. I suggest checking and replacing the air filter if it is dirty.
Another possible cause could be a malfunctioning fuel injector. Have a mechanic check and potentially replace the fuel injector.
A faulty spark plug could also be the culprit. Consider replacing all spark plugs to see if that improves the idle.
