2010 BMW 335D Unknown Or Other Problems

I OWN 2 BMW 335D'S, ONE A 2010 AND THE OTHER A 2011. I CANNOT KEEP THESE CARS ON THE ROAD. I HAVE HAD "SERVICE ENGINE SOON" LIGHTS CONSTANTLY. EVERY CODE LEADS BACK TO THE EMMISSIONS SYSTEM ON THESE DIESELS. THE LATEST IS AN SCR CODE THAT IS THOUSANDS OF DOLLARS TO REPAIR. BMW CAME OUT WITH A 10 YEAR 120K MILE EXTENDED WARRANTY ON THE PROBLEM. THEY SHOULD HAVE COME OUT WITH A RECALL! I HAVE HAD SO MANY SERVICE ENGINE LIGHTS I CANNOT AFFORD TO KEEP THESE CARS ON THE ROAD. THESE CARS ARE WORSE THAN THE VW DIESELS. THE CARS RUNS GREAT, YET BECAUSE OF THE SERVICE LIGHTS THE RPAIRS ARE MORE COSTLY THAN THE CARS ARE WORTH. I ASKED THE MURRIETA BMW TO ASK BMWNA TO SEE IF THEY WOULD REPAIR THE SCR ACTIVE TANK AND WAS DECLINED. I RUN THE 2010 BMW MANY MILES ON...
