Hi All I have a 2009 accord 2.2 diesel, when my engine is cold and i start it , I get a puff of smoke from exhaust drives perfect besides, and doesn't happen when warm, from time to time I get a smell of fumes in car .thanks for any advice
White smoke would normally indicate a bit of water vapour is getting into the combustion chamber.. if it was dark grey or black I would say unburnt fuel, and if blue then engine oil. Is the engine losing any coolant?
Actually I’m not sure if the Accord gives a low coolant warning, but I wouldn’t rely on that anyway even if it did, worth checking and keeping an eye on it. If it’s just a small wisp of white smoke on first startup and no other issues or loss of fluids, I wouldn’t be overly concerned. Even cold ambient conditions can cause this.
