Why does my BMW 5 Series keep stalling when I come to a stop?

I recently purchased a BMW 5 Series and have noticed that it stalls every time I come to a complete stop. This can be quite frustrating and dangerous, especially in heavy traffic. What could be causing this issue and what steps can I take to fix it?

First, check if your idle control valve is functioning properly. This is a common issue that can cause stalling when coming to a stop. If it is faulty, it will need to be replaced.

Another possible cause could be a dirty air filter. A clogged air filter can disrupt the air-fuel ratio and cause stalling. Consider replacing the air filter and see if it improves the issue.
