I've noticed that my Audi A1 has been idling rough lately. What could be causing this and how can I fix it?
ReplyOne of the most common causes of a rough idle in an Audi A1 is a dirty or faulty idle air control valve. I recommend cleaning or replacing the valve to resolve this issue.
Another possible cause is a clogged fuel filter. If your car is due for a fuel filter replacement, this could be the culprit. I suggest replacing the filter and seeing if that improves the idle.
A vacuum leak can also result in a rough idle. Check for any cracked or disconnected vacuum hoses and repair or replace as needed to fix the issue.
