Default 99.5 audi a4 engine dies after starting

my car when its cold like under 40 degrees Fahrenheit (4 Celsius ) the car will crank, after a few attempts the car will start badly have a fluctuating idle and just shut off. and if its colder like say under 30F itll misfire with blinking cel. once the car is warm which is usally like 30-50 start attempts it runs okay and doesn't stall.

- I replaced 4 pin coolant temp sensor still no luck.

- I tried starting it with maf unplugged and it starts and idles a lot smoother but still shuts off.

- Fuel filter was just replaced, pump sounds just fine.

- I just put in a new battery in november

- I get 3 codes; 18010(I only get when trying to start) 17604, & 16518

heres a vid that visualizes my issue (not my video):

any ideas? all help is appreciated
