In cold weather, the normal procedure for diesel engines is that you need to wait for the glow plugs to heat up and the indicator "light " go out before you try to start the engine. Trying to start the engine without waiting for this to happen can take more attempts. Are you doing this I wonder? If so, there could be other reasons for non starting to consider.

As this is a common rail diesel engine,the glow plugs are not needed for cold start unless the ambient temperature is sub zero.I would get the injectors tested.

The Doc is correct. Common rails are direct injection. The primary purpose of the glow plugs is to improve running and emissions during warm up. They do not switch on for preheating unless the ambient air temperature is typically below 2 degrees. Indirect injection engines do need glow plugs for cold starting.
