N57 rough cold running

[Kedge]

Hi,

My E92 325d with the N57 engine has developed a lumpy idle a few seconds after start up, which then clears pretty quickly.
There’s no fault lights being generated.
Are there any software experts out there that can tell me how to investigate this issue?

Cheers,
Dave

Looks like my version (5.0) does not recognise my DME, so looks like I'm going to be quite limited in what I can do myself at the moment.

I have managed to pull the following codes;
