HELP PLEASE!!
I live in NY it was about 15 degrees this morning I went to start my 2007 c230 and it fluttered then the service engine light came on followed by an image of a red battery. Then the white smoke came …it is a heavy white smoke…the car is 8 months old with 23,000 miles… I read through the manual and it suggested to turn on and off the car 3 or 4 times…I did that and now it starts and sounds fine..BUT the white smoke continues…any suggestions!!!!
Ps. I use 93 supreme Exxon fuel… have about a half a tank.
I did leave the car with the gas light on for like 3 or 4 days without driving???...put gas in last night and had no problem until this morning.
White smoke is normal when you first start the car in the winter especially when its that cold, but I'm going to assume you know that and you're saying theres a TON of white smoke?
Check your coolant level. White smoke (when not normal from the cold) means you're burning coolant. If that's the problem then you need to get to a mechanic.
If the car is still under warranty... why would you not have it towed to the dealer and have them sort it out? You're not paying for it... let them deal with it.

I would not agree that white smoke is normal, unless it is a diesel, which it is not in this case. Your B service is due at 26000 miles, but is it possible that you have had your oil changed recently? If your crankcase is overfilled you can get white smoke especially if you park on a hill (nose up). This happened to my car after the first oil change. I reduced the oil level and never had the problem again. We've had a cold winter here in Illinois, and have not had a reoccurance of white smoke all season. Also, its possible that the service engine light came on if the oxygen sensors were fouled.

Oil burning comes in the form of blue smoke (bluish hue) and has a specific smell which is easy to identify.
White smoke (steam) means you are burning coolant.
SOME white smoke (steam) IS NORMAL on a cold winter day as the car warms up. The reason it happens is because of condensation sitting in the exhaust which turns into steam as things warm up.
Obviously a large or larger then normal output of white smoke means there is a problem.
Obviously you need to get the car looked at, but the first thing I would do is check the oil / coolant levels. Also check to see if there is oil in the coolant or coolant in the oil.

Absolutely agree with jrsmith_68, the same happened with me when accidentally oil was overfilled and on next day it get me with white smoke and odor smell, once oil was reduced it gets to normal
In my experiences it sounds like it's either coolant being burned.(like arc2001 previously mentioned). or you have a fouled sensor like jrsmith_68 said. if it was a fouled sensor, your engine could be running very rich and unable to burn all the fuel being dumped in the cylinders. This would create a white smoke that has a very potent smell. vs. burning coolant due to a leaky head gasket which would result in milky oil and/or oily coolant, also producing white smoke but with less of a pungent odor and more of a musty smell. Either way the dealer will be able to tell you the problem indefinatly. just my .02
