My Audi A7 has been stalling at idle more frequently lately. The check engine light is not on and it runs fine otherwise. What could be causing this issue?
ReplyThe most common cause of stalling at idle in an Audi A7 is a dirty or faulty mass airflow sensor. You can try cleaning it with mass airflow sensor cleaner and see if that improves the issue.
Another possible cause could be a vacuum leak. Check all vacuum lines and connections for any cracks or damage. You may also want to have a mechanic perform a smoke test to detect any leaks.
If your A7 has been regularly serviced and maintained, it may be worth having the fuel injectors checked. Over time, they can become clogged or dirty, causing issues with idling and performance.
