2010 Audi A3 1.6tdi starts but cuts out

[Amjadali]

Hi guys I need some help please, with all the garages closed I am struggling to resolve an issue with my car. I have a 2010 Audi A3 1:6tdi with 75k miles on the clock, anyway since it’s been cold the car starts but cuts of within seconds and the gas pedal is not responsive. I have to try and start the car like 15-20 times and then it works fine for the rest of the day. Leave it for the next day and same problem. No fault codes and changed the fuel filter, any help would be a great help. Thank you
