Why does my Audi A4's engine keep stalling when I come to a stop?

I have noticed that whenever I am driving my Audi A4 and I come to a complete stop, the engine tends to stall. It is very concerning and I am not sure what the cause could be. Can anyone provide some insight or advice on how to fix this issue?

The most common cause of stalling at a stop is a dirty or malfunctioning idle air control valve. It regulates the amount of air that enters the engine while idling. I would recommend getting it cleaned or replaced to see if that resolves the issue.

Another possible cause could be a faulty throttle position sensor. This sensor is responsible for sending signals to the engine control unit to adjust the throttle opening. If it is not functioning properly, it can cause stalling at stops. Have your mechanic check it out.

Have you checked your fuel pump and filter? If they are clogged or failing, they can cause stalling at stops. If you haven't had them checked or replaced recently, it might be worth looking into.
