The colour of the smoke is an off white , a neighbour thinks it may be points, as I have checked all oil and h2o levels which are fine, as for engine on light I'm not sure as to what I'm looking for, there are no warning light visible once the car has started- which is sluggish to start and shuddering when idle

yes 09 2.0 tdi 120 bhp

Expert:  Greg replied 4 years ago.
Okay good this has nothing to do with the points as your neighbour thinks.

Now the gray smoke, is this only on start up, or all the time , will the smoke clear up once the engine is hot and then run good at idle .
