How can I troubleshoot my Audi A2's engine stalling issue?

I have noticed that my Audi A2's engine occasionally stalls while idling or while driving at low speeds. This can be quite inconvenient and has caused a few close calls on the road. What could be causing this issue and how can I fix it?

One potential cause for engine stalling in an Audi A2 could be a faulty fuel pump. Have it checked and replaced if necessary. Additionally, make sure to use high-quality fuel and keep up with regular maintenance to prevent any further issues.

Another common reason for engine stalling in any car is a vacuum leak. Check for any damaged or disconnected hoses and replace as needed. You can also try cleaning the throttle body and idle air control valve to improve engine performance.
