How do I troubleshoot a rough idle in my Audi A6?

I've noticed my Audi A6 has been idling roughly lately. What could be causing this issue and how can I fix it?

There are a few potential causes for a rough idle in your Audi A6. It could be a problem with the spark plugs, fuel injectors, or the air flow sensor. I recommend taking your car to a trusted mechanic to diagnose the issue.

One common cause of a rough idle in the Audi A6 is a dirty throttle body. You can try cleaning it yourself or bring it to a mechanic to have it cleaned.

Another possibility is a vacuum leak in the engine. This can cause the engine to idle roughly and may also result in other symptoms. It's best to have a mechanic check for any leaks and make repairs if necessary.
