just noticed white smoke from exhaust in the morning, cold day

 

You're going to make me cry, please stop.

If it smokes on warm days something is wrong, but it's normal for cold days.

 

I’ve noticed this too, even on warmer days (60-80 degrees). Is it a whispy kind of smoke or a full fledged cloud? Mine happens randomly but always as the car is warming up and never after it reaches operating temp. I read somewhere that if it is whispy then its probably condensation/water that was left in your exhaust system. Still worrying though.

 

Most likely from condensation, if your car is all wet or smoggy when you leave your house early morning (not sure what to call it). It may be the condensation, my brothers clk320 does the same thing.

 

My C180 2010 model has the same thing, repairer said it might be the engine giving way and advise to go for overhaul. Just wondering if its necessary ?
