My TD4 smokes quite heavily on first time start-up, but only when the ambient temperature is fairly mild. When it is freezing, frosty etc, it starts up with minimal smoke - any ideas, folks, what might be the root cause of smoke when it is milder?
 
Any thoughts, anyone? Why should it not smoke at all on first start-up when it is really cold outside? Something temperature/sensor related?
