Hi

I'm posting this video incase anyone can help. I'm at my whitsend with this car 2011 cdti manual A20DTH. Argh well can't upload video, but when I start the car from cold any time of day or outside temperature it  hunts like a misfire, once it's warm it's as smooth as anything, there is also a faint whiff of diesel, like unburned, sweetish smell when it first starts.

Any ideas?

I have cleaned throttle body, egr, new map s
