The Mégane II Owners' Club

Hi to all,

I know that this topic has been already discussed few times.... I was following the topics, but it seems that mine is does not match with any of the symptoms described earlier.
Renault Megane II CC 2005 1.9 DCI
As the title said, a lot of smoke when engine is warm as described bellow:

ENGINE COLD:
Starting engine - NO SMOKE
Idle - NO SMOKE
Starting to move (from 0 km/h) - NO SMOKE
Accelerating (pedal down in gear) from 1000 to 2200 rpm - NO SMOKE
Accelerating (easily in gear) from 1000 to 2200 rpm - NO SMOKE
Accelerating (pedal down in gear) from 2200 to 4500 rpm - NO SMOKE

ENGINE WARM:
Starting engine - NO SMOKE
Idle - Lite SMOKE
Starting to move (from 0 km/h) - SMOKE
Accelerating (pedal down in gear) from 1000 to 2200 rpm - SMOKE
Accelerating (easily in gear) from 1000 to 2200 rpm - NO SMOKE

I have this Friday a service reservation for investigation, but I would like to know if any of you have any idea

Many thanks!
