E91 325d Rough Start Up

I have a problem with cold starts at cold ambient temperatures, the car is very rough as if running on less cylinders than the six it's got. This lasts for upto six seconds before normal smooth running resumes. No other issues manifest them selves.
The glow plug light seams to work if the ignition is turned on and left for a short time and the engine is not started.
The rev counter does not pulse during the rough running it shows reduced revs and the the revs pick up and everything is smooth.
Any ideas?
