The smoke is light in color (almost white) and scentless, doesn’t smell like anything, has almost no smell. It comes mainly from those small vents on the engine cover (under the hood, next to the oil cap, there are small vents). I have been driving it for a month now, this happened twice so far, some 15 days apart. Both times I have noticed it after I stopped driving and exited the car. I have checked the coolant tank, it is almost full. I have also checked the radiator cooling fan and it’s spinning properly. All help is greatly appreciated.
- The car in question is a 2009 Mercedes-Benz E220 (W212) and its millage is 340 000 km currently. It’s also a 5G tronic automatic.
It is probably from excessive blowby from the crankcase. Check for a blocked PCV valve and the breather tube running from the valve cover to the air cleaner.
