2011 BMW 328 Engine Problems

MY BMW 328I E93 HAS THE SERVICE ENGINE SOON (SES) LIGHT COME ON WHILE I WAS DRIVING ON THE HIGHWAY. THE COMPUTER SHOWS ERROR CODE 2B3A (P1449 DMTL SYSTEM FAULT). I CLEARED THE CODE AND IT CAME BACK A WEEK LATER. I TRIED REPLACING THE GAS CAP AND THE ERROR STILL COMES BACK THE SAME. I WAS DOING FURTHER RESEARCH AND CAME ACROSS THIS ARTICLE (ATTACHED) FROM NHTSA.GOV DESCRIBING THE SAME EXACT PROBLEM, WITH THE SAME EXACT CODE AND EVEN MY ENGINE IS THE SAME N52K FOR MY E93 328I. HTTPS://STATIC.NHTSA.GOV/ODI/TSBS/2012/SB-10051299-3508.PDF THE DMTL PUMP IS THERE TO HELP REDUCE EMISSIONS AND IF THE SYSTEM IS FAULTY, THE BMW DEALERSHIP SHOULD HONOR THE REQUEST FOR SERVICE WORK TO REPLACE THE DMTL PUMP UNDER THE EMISSIONS/EXTENDED EMISSIONS WARRANTY. I CALLED AND THEY SAID THERE'S NO RECALL FOR THIS VIN SO THEY CAN'T HELP ME...AND THEY ARE MAKING ME PAY FOR THE DIAGNOSTIC...

ELECTRICAL SYSTEM MALFUNCTION. BMW DEALER SHIP NOT TAKING RESPONSIBILITY FOR THESE DEFECTS, THE SPARKS PLUGS KEEP BURNING OUT DUE TO THE CAR OVERHEATING.

BLOWER MOTOR WIRING AND POSITIVE CRANKCASE VENTILATION (PCV) VALVE HEATER. CAR FEELS HOT SOMETIMES I WENT TO THE DEALER ALREADY AND WAS TOLD SOMEONE WOULD CALL ME BACK IS BEEN OVER 2 MONTHS ALREADY

ALUMINUM HEADBOLT SHEARED OFF CAUSING INTERNAL DAMAGE RESULTING IN CAR LOSING POWER AND NOT BEING ABLE TO GET OFF THE ROADWAY. THIS IS AN N52 ENGINE AND COMPLAINTS ARE THAT THIS PROBLEM IS SOLELY CAUSED BY AN OVER TORQUE OF THE BOLT DURING MANUFACTURING.
