Why does my Audi A8 keep stalling while in idle mode?

I've noticed that my Audi A8 sometimes stalls when I'm stopped at a red light or in heavy traffic. What could be causing this issue and how can I prevent it?

This could be a sign of a faulty idle control valve. It's important to get this checked and replaced if needed, as it can lead to further engine damage if left unfixed.

One possibility could be a clogged air filter. If the air filter is dirty or clogged, it can cause issues with the air-to-fuel ratio and lead to stalling. Try replacing the air filter and see if that helps.
