There are a few potential reasons for high oil consumption in a BMW 3 Series. One possibility is that there is an oil leak somewhere in the engine, which could be caused by a faulty gasket or seal. Another possibility is that the piston rings are worn and allowing oil to leak into the combustion chamber. It's also possible that there is an issue with the PCV valve or the oil pressure sensor. I recommend taking your car to a trusted mechanic or BMW dealership for a thorough diagnostic check to determine the exact cause.
