Hello! I have a LEXUS IS 220d with a annoying problem and apparently no cure.
A while ago my car started to pull aut white smoke, this smoke comes only under certain conditions: when the outside temperature is below 10 degrees; when the water begins to warm (the cold engine does not smoke); when i drive in the town (low speed, traffic lights); when on the highway the smoke disappears. The smoke comes with a strong smell of burning fuell.
I tried various remedies proposed by dealer service stations including: i have cleannd the EGR valve, I cleaned the pressure regulator, I checked if I leaked antifreeze, oil, etc.. , I made a regeneration on the DPF.
Besides the smoke, the car works perfectly, no lack of power, does not give any error on tester, does not consume oil or other liquids in addition to normal.
What should be the problem?
I attached a video of another Lexus with the same problem. ( min 0.58)
