The oil pump failed and needs to be replaced. Yes it is available for inspection. If the pump ds not get replaced, the oil will not flow through the car like it’s supposed to and the engine could seize up and stop working. My dealership confirmed that the oil pump has failed. Another service center mentioned that it’s a common problem with certain BMWs because of the plastic component that they used. Because of the issues, BMW switched to metal but never issued a recall to fix those who still have the plastic component. The first error message I received said that the engine oil level is low and I need to add 2 qts of oil. When I tried to digitally measure the oil levels after oil was added, it wouldn’t work. It would load to about 20% and then go back to the initial screen without taking a reading. I didn’t realize that was a symptom at the time but the dealership confirmed it. I took it to the dealership within a day of receiving the error message.
