I've got a 2007 e320 Bluetec. I've had it for a couple of years and it has always started well in cold weather. This sustained cold has done it in somehow.

It's -17 this morning and it started right up and ran for two minutes and then stalled. I've treated the fuel with Diesel 911 and put a new fuel filter in in November. I can try it after five minutes and it will start right up again and stall. When the temperature gets up to around zero, it will more likely start. This has happened several times during the current cold snap.

Seems like fuel is getting to the engine as it starts repeatedly, but that it may be restricted in the fuel line. Is that reasonable or may there be another reason?

Thanks for any suggestions.
