My 2018 BMW 340I started misfiring, cutting fuel to cylinder 3 and 6, and was also smoking XTREMELY bad. I was doing a log for my turner and mid pull my car started cutting boost and fuel and also started smoking heavily. when I pulled off to check the car out, I noticed an extreme amount of oil on the PCV cap. But I checked the gasket for any tears, and it seemed to look fine. The PCV cap also sealed properly. My car threw a CEL and Drivetrain Malfunction code, the codes are 120408, 140001, 140002, 140010, 140310, 140601, 140602, and 140610. my turner said its most likely the PCV but seeing that it all looks fine I'm at a standstill. Anything helps. Thanks!
