Audi A4 B7 2.0tdi starts then cut out in cold morning

[AkhiB7]

Hi, my car drives fine once I get it started and it's up to temp. And throughout the day it's starts up fine even if the engine cools down. My problem is when I leave it over night and go to start it in the morning. And the outside temp is below 5°c it starts and cuts out straight away. I have to try start it with my foot planted on the accelerator multiple times before it holds idle. This morning the outside temp is -3° and after trying for about 15 mins I've given up.

Has anyone else experienced this? Anyone know how to fix it? I'd really appreciate any help I could get 

I'm a new diesel owner so I don't know much about them

Petrol or diesel Akhi? 
Can we take it the battery turns the engine over ‘enthusiastically’? 
Kind regards,

Gareth.

It's a diesel, and yeah the battery turns the car over. I've done a bit of searching online and had a few opinions here and there. I think it just needs a new set of glow plugs or maybe has a faulty injector line 

But any advice would be appreciated thanks Gareth 

I've attached a video of what is doing
