Crankcase (pcv) problems of the 2011 BMW 335

Years of my 335d overheating and stalling and dealer cant figure out the issue. I’ve replaced injectors, done carbon blasting, replaced nox sensor, replaced whole battery/electrical components. Just recently replaced the all belts, hoses, and egr module to avoid catastrophic results. After removing the components you can see fluids got mixed and even got into my turbo all because of the egr was leaking. So many identical issues resulted in recalls from BMW for almost every single model from early 2000s to new models due to faulty egrs, except the 2011 335d. And of the nearly 1 million vehicles recalled by BMW this year alone, only the 2011 335d is not recalled for faulty pcv and egr which was finally determined by the dealer to be the cause of my overheating, black particles coming from the exhaust, melted plastic under my hood, and disgusting smell from air vents. There are numerous complaints regarding this same exact vehicle with the same exact issues on NHTSA and nothing is being done. Only when these cars catch on fire and result in a casualty will BMW finally add all model types to their recall lists. For now they will keep adding models one by one, pretending they do not have an extremely dangerous issue with all their cars. Ridiculous.

I had just parked and about a minute later, there was a huge amount of smoke coming through the front cabin vents and hood. I immediately turned my car off and opened the hood to find more smoke and hearing popping sounds coming from my catalytic converter. The smoke left residue all over my windshield as well as an unpleasant smell lingering in the car. I emailed my local mechanic and he told me this is likely my pcv and not a vcg leak like I thought it was. This problem had scared me from driving my vehicle again because I was worried a fire would start whether I was in the vehicle or not. I took it to my mechanic to get it repaired and was charged $1700 for it. I had no lights or unusual car prior to this happening.
