Issues with cold engine

We have a 4 year old 35i with DCT. In the last few weeks, on start up the revs seem very low almost as though it is going to stall and there is some juddering. As yet it never has but it's a bit rough for 10 mins or so until the engine warms and then it's fine.
We've had it for near enough a year and there was no problem when the temp dropped last year.
It is under AUC warranty still so will get them to take a look, just wondered if anyone else has had this.
 
My guess is either HPFP or Injectors as both are known weak point of this engine and there are posts on all forums relating to common N54 failings. Once replaced most users don't experience further issues.

I've had my HPFP replaced under warranty.
