First, I would recommend checking your spark plugs and ignition coils. These are common causes of rough idle in Audis and may need to be replaced. Also, make sure your air filter is clean and replace if necessary. Finally, consider taking your car to a mechanic for a diagnostic check to pinpoint any other potential issues.

Another thing to consider is the fuel injectors. They may be clogged or not functioning properly, causing an uneven fuel distribution and leading to a rough idle. You can try using a fuel injector cleaner to see if that improves the issue before taking your car to a mechanic.
