Why does the Audi A3 sometimes have trouble starting?

My Audi A3 has occasionally had issues starting, where it idles and then shuts off. What could be causing this?

It sounds like your Audi A3 may be experiencing a common issue with the fuel pump. I recommend taking it to a trusted mechanic for a diagnostic test to confirm and replace if necessary. In the meantime, try avoiding low quality gas or letting your fuel tank run low to prevent further issues.
