My 2019 Audi A4 has been idling roughly lately, making me concerned about the engine. What could be causing this issue? Are there any potential fixes I can try before taking it to a mechanic?
ReplyA rough idle can be caused by a variety of factors, such as dirty fuel injectors or a faulty oxygen sensor. It's best to have a mechanic run a diagnostic test to identify the exact cause.
One common fix for a rough idle is to clean or replace the air intake filter. This is a simple and affordable solution that can often resolve the issue.
