First, check the fuel filter and make sure it is not clogged. This can often cause issues with starting and fuel delivery. If the filter is clogged, replace it with a new one.

Another common cause for fuel system issues in the Audi A1 is a faulty fuel pump. You can test the fuel pressure to see if it is within the proper range. If not, the fuel pump may need to be replaced.

Make sure to also check the fuel injectors for any clogs or leaks. These can also cause issues with the fuel delivery and engine performance. If needed, have a professional clean or replace the injectors.
