The contact owns a 2017 BMW 530i. The contact stated that while the vehicle was parked, the message "refill coolant" was displayed on the instrument panel. The contact exited the vehicle and discovered a puddle of blue liquid underneath the vehicle. The vehicle was taken to a dealer, where it was diagnosed that there was a leak in one of the hoses and that the hose needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the dealer, where it was diagnosed and determined that the radiator and hose needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the dealer for a diagnostic test; however, the vehicle was not yet diagnosed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.
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.
This vehicle has been re[aired for cooling system problems multiple time by BMW dealer. Now that the vehicle is approximately 90 days outside of warranty a cooling system leak has arisen with the engine oil cooling interface. On-line there is mention of this issue with the b46 engine which is in this vehicle developing coolant leaks. The repairs are very expensive for this apparently well know issue.
