Why is my Audi A6 stalling when I come to a stop?

I've noticed that my Audi A6 stalls when I come to a stop at a traffic light or stop sign. It only happens occasionally, but it's concerning and I'm not sure why it's happening. Is this a common issue with Audi A6s or is there something wrong with my car?

It's possible that there could be an issue with the idle control valve in your Audi A6. This valve helps maintain an ideal idle speed for your car, and if it's malfunctioning, it could cause your car to stall when coming to a stop. I would recommend taking your car to a certified mechanic for a diagnostic test to see if the idle control valve needs to be replaced.

Another potential cause could be a dirty air filter. A clogged air filter can restrict airflow to the engine, causing it to struggle and potentially stall when idling. It's a good idea to check your air filter and replace it if it's dirty. You can also try cleaning it first with compressed air before replacing it.
