Why does my Audi A2 keep stalling while idling?

I have noticed that my Audi A2 has been stalling while idling recently. It doesn't happen all the time, but it's becoming more frequent. What could be causing this issue and how can I fix it?

One possible reason for your car stalling while idling could be a dirty or faulty idle air control valve. This valve controls the amount of air that enters the engine while idling, and if it becomes clogged or malfunctioning, it can cause the engine to stall. I would recommend cleaning or replacing the valve.

Another common cause for stalling while idling is a malfunctioning fuel pump. If the fuel pump is unable to provide enough fuel to the engine, it can result in the engine stalling. I would recommend having your fuel pump checked and possibly replaced if needed.
