I have audi tt w reg Dashpod has been going crazy for months but resets itself on sat i put £40 petrol in two days later went to start it gage showing empty but clearly has petrol as only went to local shop and school run.

The battery works it seems to want to turn over but no fuel is going through any advice

 

can you hear the fuel pump cycle for a second when you turn the ignition on without starting the engine??check your fuses
