Hello,
I've searched and could not find anything in W210. I'm getting white smoke even after my engine has completely warmed up. Not too much, but I can see it in my rear view mirror.

On other models, some say valve timing, fuel injector, coolant, water leak (whitish), oil leak (bluish), etc. For W210 though, what could it usually be?

Does the exhaust smell normally or do you notice a much different smell??

To be on the safe side, when the engine cools I would check the coolant level in the expansion tank. Is the level where it should be??

If it is the good news, then you have been experiencing the "Hanuka candle effect" or you have had to much egg nog!!!

It could just be the normal moisture in the exhaust condensing in cold air, like your breath does. If it is really smoke it will linger long enough to drift away in the wind. If it is smoke, it could be either unburned fuel or burned lube oil. They can be distinguished by smelling the smoke.
