This is the second time I’ve had overheating issues, and it now seems more severe. I’ve noticed both coolant and oil leaking, and the car is unsafe to drive. Also fault codes related to emission. Here are the symptoms I’m experiencing: •Smoking: The car I started smoking, likely from oil or coolant leaking onto hot engine parts. Caused me to pull over at midnight on side of highway and get towed •Coolant and oil mixing: I’ve observed signs of contamination, which may indicate a gasket failure or internal leak. •Safety concerns: Due to the risk of overheating or fire, I am not driving the vehicle. •The engine could overheat, leading to catastrophic damage. •Leaked oil on hot parts could increase the risk of fire. •The compromised lubrication can cause engine seizure. I suspect the issue may be related to plastic components, as I’ve read they can become brittle over time and lead to leaks Also, the these BMWs involves the water pump's electrical pump connector allowing water to drip from the positive crankcase ventilation system through the seal, potentially causing a short circuit.
