Hello
Sorry to hear your trouble.
It would be good if you could scan for codes using VCDS or similar.
What's the service history like? Have you had coils & plugs replaced at all? How many miles/kms?

I am suspecting fuel lines (air) , fuel pumps (no pressure) , air flow sensor (between air filter and throttle body) , PCV valve.

You might try disconnecting the air flow sensor and seeing if it will run in a default mode.

Cheers
Ben.
