white smoke from exhaust, burning oil?
2014 M235i, original owner. Never observed this white smoke issue before. I am not a mechanic but google around indicates possible:
Crankcase Ventilation Valve CCV/PCV valve issue Damaged cylinder head It's not a lot of smoke, just a bit. Passenger side exhaust pipe only. Exhaust sound is off too. Never seen it in almost 10 years of ownership. White smoke, mostly on ignition start up. Took it to a local BMW branded shop (not a dealer) and they basically said it's fine, keep driving, nothing too bad . Only thing they found was the turbo throttle pipe (aka charge pipe) is a bit cracked/damaged where it connects to the engine. Ran the oil level check on the car and it's low, on the way towards below minimum levels . That doesn't seem good. Thoughts? Opinions? Take it to another mechanic? |

Burning oil is usually bluish. Carbon is black. White is usually water/coolant.
Oil being THAT low is pretty concerning, whether it's related to your smoking issue or not. Definitely need a full checkup and probably well worth doing oil analysis too. |

I started it today and it was just a ton of smoke, so much even the engine compartment had smoke in it in just ~60 seconds. There is no way this is normal or okay to drive. I am making an appointment with a different BMW service shop around me. |

Well, better safe than sorry. It's true I don't drive the car much anymore since I started WFH full time. It used to be my daily commuter. Need to get it in the garage for the winter. I guess it's my Sunday driver now . |
