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 FEE...BUT I DO IN FACT HAVE MY EMISSIONS WARRANTY STILL IN EFFECT FOR THE VIN WHICH IS 8 YEARS OR 80,000 MILES, WHICHEVER COMES FIRST. IT SEEMS THAT THERE NEEDS TO BE AN ACTIVE RECALL FOR THESE FAULTY DMTL PUMPS/SYSTEMS AS THIS PROBLEM EXISTS FOR ENGINES LIKE MINE -THE N52K ENGINE. I ENCOURAGE THE NHTSA TO TAKE A LOOK INTO THIS MATTER AND WORK CLOSELY WITH BMW NORTH AMERICA TO INSTITUTE A REMEDY FOR THIS. THANK YOU IN ADVANCE AND HAVE A NICE DAY.

TAKATA AIRBAG PROBLEMS ON THE PASSENGER SIDE OF THE VECHICLE. WHEN I BOUGHT THIS CAR FROM THE THIRD PARTY DEALERSHIP, 'CHASE AUTOPLEX' HE RESETTED THE SETTINGS EVERYTHING WAS WORKING PROPERLY, BUT AFTER GETTING HOME, THE NEXT DAY MY CAR SHOWED AIRBAG PROBLEMS. WHEN I CALLED HIM, HE SAID HE CAN'T HELP ME OUT WITH IT. SO MY QUESTION IS THAT, IF YOU GUYS CAN HELP ME GET A RECALL ON THIS AIRBAG, SO I DON'T HAVE TO SPENT MONEY ON IT MYSELF, I WILL APPRECIATE IT. THANKS

SOMETIMES WHEN I TRY TO OPEN THE DRIVER'S SIDE DOOR USING THE MECHANICAL HANDLE, DOOR DOES NOT UNLOCK. I HAVE TO USE MY KEY FOB TO REMOTELY UNLOCK THE CAR BEFORE THE DOOR HANDLE WILL WORK TO OPEN THE DOOR.
