Leakage? Check Engine light situation. I received my car with a cracked Air Intake Boot and Air Hose. Ive been driving it for deliveries and regularly doing hard pulls. Last night my engine ran hot and had white a significant amount of white smoke. I parked it for the night. This morning the check engine light came on when powering up the battery but not when car is running. I made this video below of what I saw, after I saw it. https://vimeo.com/239677506 I have the Air Intake Boot, Air Hose and the Distribution Piece on the way. I'm thinking I need to do a full coolant flush as well and all will be well after? :confused: I'd appreciate any feedback! :smile: |
BMW coolant is blue, you lost coolant from one of the plastic hoses most likely. |

What year is your car? There are two plastic coolant distribution pipes that commonly fail. If it were a coolant hose you would most likely see it. You can pressurize the system and look for leaks (a safe way to test it). |

Well, read the post above with the pictures in it about the coolant passages/parts. If you are not experienced enough take it to auto tech. |

I'll now asses these parts and see how things go. Thank you so much! :smile: |
I did a top up with distilled and the water flows straight to the floor. Here is a video showing where it’s flowing from: https://vimeo.com/241100280 What is it I need to replace? |
Stop wasting your time replacing coolant hoses and pipes. You will need a cylinder head or the whole engine. |

Regardless, if you are not able to start tearing down the engine, you will have to take to a mechanic. I suggested that the rear coolant pipe is bad (which could explain water running down back of engine) and bazar01 is saying that the headgasket is most likely blown, which is evidence by the white smoke coming out the exhaust. The coolant or water is mixing in the combustion chamber and causing white smoke out the exhaust. Does the exhaust gases smell like coolant? Either way, sounds like you need to take it to a shop. |

Oh, then it must be hitting the exhaust then and is causing the smoke. Must still be the coolant tubes.... |
Ok. Replace the plastic coolant pipes between the firewall and rear of cylinder head and hope for the best that will fix your overheating issue. Include also the plastic pipe under the intake manifold. Good luck to you! |
