What is the cause of the rough idle in my Audi A3?

I have noticed that my Audi A3 has a rough idle when I first start the engine in the morning. However, it seems to go away after a few minutes of driving. What could be the reason for this and is there anything I can do to fix it?

One possible cause of a rough idle in an Audi A3 could be a dirty or faulty mass air flow sensor. I recommend getting this checked and cleaned if necessary.

C

Another reason could be a clogged fuel filter. If it hasn't been replaced recently, this may be the culprit and should be replaced.
