Why is my Audi A2 constantly stalling while idling?

I have been encountering an issue with my Audi A2, where it consistently stalls while idling. This has been happening for the past week and I am unsure of the cause. What could be the potential reasons for this and how can I fix it?

There are a few potential reasons for your Audi A2 stalling while idling. It could be due to a dirty or clogged air filter, which is restricting the flow of air to the engine. It could also be a problem with the fuel system, such as a malfunctioning fuel pump or dirty fuel injectors. Additionally, it could be an issue with the idle control valve or the ignition system.

To fix this issue, you should first check and replace your air filter if it is dirty. Then, have a mechanic inspect and potentially clean or replace your fuel pump and injectors. It may also be worth getting your idle control valve and ignition system checked. Regular maintenance and tune-ups can also help prevent stalling issues in the future.

Another possible cause for the stalling could be a faulty mass air flow sensor. This sensor is responsible for determining the amount of air entering the engine and adjusting the fuel and spark accordingly. Have a mechanic check and potentially replace this sensor if it is malfunctioning.
