2008 BMW 335I Fuel/propulsion System Problems

As of recently I've been smelling a gas smell after driving my vehicle. No matter the distance or time I smelled the odor of gas. I am a certified automotive technician, so I decided to diagnose the problem myself. I put my vehicle in the air and spotted a wet spot of gas on the bottom left side of my fuel tank. To continue my diagnosis process I googled to see if anyone dealt with a similar issue. Seen a decent amount of people confirming the problem. A leak from the D/S fuel sending unit. So I take off my rear seats, and takeoff the fuel sending unit cover. Once the cover was off seen multiple cracks along side top of the unit. No warning lights was present, however did notice MPG was getting worse and worse. the little cracks makes my vehicle a fire hazard. I was able to have the replacement part ordered for about $140.

The engine and all electrical components including power steering spontaneously cutout while driving, usually while engine isnt being stressed at all, sometimes while idling. If the car is rolling, i have to restart the engine while driving and using manual power to steer. Obviously, this is a huge safety problem. I've just had the alternator and battery replaced, and they test fine. This has happened at least 50 times and I've reduced time driving vehicle until I solve the issue, which has persisted at least 6 months. I asked the BMW dealer about the following recall, and they claim they already performed it years ago after I already owned the car, without my recalling being told it was done. However, the symptoms are back, and BMW refuses to do anything about it at this time: Report Receipt Date: FEB 07, 2013 NHTSA Campaign Number: 13V044000 Component(s): ELECTRICAL SYSTEM Potential Number of Units Affected: 504,545 All Products Associated with this Recall Details 2 Associated Documents Manufacturer: BMW of North America, LLC SUMMARY: BMW is recalling 2007-2011 3-Series sedans manufactured March 2007 through October 2011. The connector for the positive battery cable connector and the corresponding terminal on the fuse box may degrade over time. Over time, the high current flow and heat from electrical resistance may lead to a breakage of the connection, and a loss of electrical power to the vehicle. CONSEQUENCE: If there is a loss of electrical power to the vehicle, the vehicle may unexpectedly stall, increasing the risk of a crash. REMEDY: BMW will notify owners, and dealers will replace the positive battery cable connector and secure it with an improved method, free of charge. The recall is expected to begin in March 2013.

I am experiencing a know issue others have complained about related to the high pressure fuel injector failure in my vehicle. There have been previous recalls for this and my vehicle should fall within the recall dates and is showing all of the symptoms of this failure yet is it some how not part of the recall. What is happening is on cold starts or even idle the car is shaking and has a very apparent misfire, I have checked the spark plugs and they indeed have fuel on them. The injectors are causing excessive fuel in the cylinder this leads to a host of problems that are potentially, catastrophic like the engine seizing while driving due to oil dilution from the fuel

I WAS TOLD BY MY MECHANIC MY FUEL INJECTORS HAVE GONE BAD AND I BELIEVE THIS IS FROM A MANUFACTURER'S ISSUE. PLEASE INVESTIGATE AS I KNOW VARIOUS PEOPLE THAT HAVE THE SAME ISSUE WITH THE SAME ENGINE, YEAR AND MAKE. I TOOK IT TO THE SHOP AFTER I TURNED IT ON TO DRIVE AND THE VEHICLE WAS SHAKING A BIT MORE THAN NORMAL, WHEN I ACCELERATED THE CAR WAS VERY VAGUELY RESPONDING TO ME. THIS IS WHY MY VEHICLE BEGAN TO MISFIRE, BECAUSE OF THE FUEL INJECTORS. I WILL KEEP ALL RECEIPTS UNTIL FURTHER NOTICE OF THIS ISSUE.

01MAY2020. BROUGHT 2008 BMW 335I TO SOUTH ATLANTA BMW DEALERSHIP TO REPLACE REAR BRAKE PADS (BASED ON INSPECTION REPORT FROM A JAN2020 APPT). IT WAS DETERMINED THAT: 1. OIL FILTER HOUSING GASKET: FILTER HOUSING GASKETS & OIL COOLER O-RINGS LEAKING OIL 2. RADIATOR HOSE REPLACEMENT. UPPER COOLANT HOSE TURNING BROWN AND SEEPING. 01MAY2020. RADIATOR HOSE WAS REPLACED ALONG WITH CONDUCTING BRAKE FLUID FLUSH AND MICRO FILTER. SAME DAY AFTER REPAIRS WERE COMPLETE THE CAR STALLS AND SHUTS OFF AND BECOMES UNABLE TO DRIVE. CAR IS TOWED BACK TO DEALERSHIP FOR FURTHER INSPECTION. UPON FURTHER INSPECTION THE FOLLOWING ARE IDENTIFIED: 1. FUEL PUMP REPLACEMENT: R&R HIGH PRESSURE FUEL PUMP & LOW PRESSURE SENSOR PER FAULT CODE 29F2 2.TURBOCHARGER - VARIABLE BOOST CONTROL SOLENOID: BOTH VANOS SOLENOIDS & OIL CHANGE PER SIB. DEALERSHIP INFORMS ME THAT THE FUEL PUMP'S WARRANTY HAS BEEN EXTENDED 10 YEARS/120000 MILES DUE TO MANUFACTURING ISSUES WITH THE FUEL PUMP. I HAVE NEVER BEEN MADE AWARE OF ISSUES WITH THE FUEL PUMP OR EXTENDED WARRANTIES FOR REPLACING. I DO THINK I SHOULD BE RESPONSIBLE FOR REPAIRS ON A MALFUNCTIONING FUEL PUMP THAT WAS POORLY MANUFACTURED. BMW SHOULD BE RESPONSIBLE FOR THE REPLACEMENT AND REPAIR. *TR

THE HIGH PRESSURE FUEL PUMP WHICH WAS RECALLED AND REPLACED IN 2011 IS PROBLEMATIC AGAIN. WHEN PUSHING THE GAS PEDAL HARDER, THE CAR STUTTERS AND DOES NOT RESPOND TO THE EXTRA POWER REQUESTED BY FLOORING THE GAS PEDAL AND MAKES PUT ME IN A DANGEROUS SITUATION. THE 'SERVICE ENGINE SOON' LIGHT CAME UP AS WELL. I PULLED THE CAR OVER WHEN I COULD, STOPPED AND STARTED THE ENGINE AGAIN AND THE "SERVICE ENGINE" LIGHT DISAPPEARED. THIS IS THE SAME ISSUE BACK IN 2011 AND RECURRING AGAIN. I SUSPECT THIS HAS BEEN THERE FOR A LONG TIME, BUT AS MY WIFE DOES NOT PUNCH THE GAS AS HARD AS ME, SHE NOTICED THIS ONLY ON FEW OCCASIONS. I NOTICED THIS TWICE IN THE LAST MONTH AND SO, CALLED THE STEALERSHIP AND LOGGING A COMPLAINT HERE. IN 2011, THEY SAID BMW EXTENDED THE WARRANTY TO 10 YEARS AND SO, THIS SHOULD BE COVERED NOW AS WELL, BUT THE STEALERSHIP ABVIOUSLY WOULD NOT ACKNOWLEDGE. HOPE OUR GREAT PRESIDENT TRUMP SHOW GERMANY THEIR PLACE, AND HOPE BMW PAYS FOR THE TERRIBLE ENGINEERING TILL ELON MUSK MAKES THEM GO BANKRUPT.

HIGH PRESSURE FUEL PUMP FAILURE COULD BE THE LOW PRESSURE FUEL PUMP NOT SO SURE GOT CODES P3090 CONFIRMED AND P142E PENDING.

I WAS DRIVING AND ALL OF A SUDDEN I COULD NOT STEER, AND THE POWER WAS GONE; IT WAS BARELY MOVING; AND THE LIGHT CAME ON SAYING TO CONTINUE TO DRIVE WITH DIMINISHED SPEED. I WAS CLOSE TO HOME ON AN ACCESS ROAD; AND WAS ABLE TO LIMP HOME. IT WAS ALMOST IMPOSSIBLE TO TURN THE STEERING WHEEL. I TOOK IT TO GLOBAL BMW IN METRO ATLANTA; AND PAID CLOSE TO $3000 FOR REPAIRS. APPROXIMATELY A MONTH LATER I HAD A PROBLEM AGAIN. THE LIGHT CAME ON AND STATED ENGINE MALFUNCTION; REDUCED POWER, PROCEED WITH CAUTION. IN DOING RESEARCH THIS MORNING; I DISCOVERED THAT THERE WAS A RECALL ON MY VEHICLE FOR THIS EXACT PROBLEM. I DID NOT KNOW IT; BUT GLOBAL BMW HAD TO KNOW IT. I CALLED BMW RECALL AND THEY CLAIM THAT THEY ARE WAITING ON THE PARTS. THIS RECALL HAS BEEN IN EFFECT SINCE 2010; SO THEY MUST HAVE THE PARTS. MOST OF THE LAWSUITS WERE SETTLED OUT OF COURT WITH A GAG ORDER; SO IT APPEARS THAT BMW DON'T RESPOND UNLESS THERE IS A FORMAL COMPLAINT; AND THIS IS THE REASON FOR THIS COMPLAINT WITH YOUR OFFICE. I WILL APPRECIATE ANY ASSISTANCE THAT YOU MAY PROVIDE.

MY CAR BEGAN TO RUN ROUGHLY AFTER A COLD START AS I WAS LEAVING MY OFFICE. AFTER A FEW SECONDS AND FEELING DECREASED POWER, I TRIED TO PULL OFF THE ROAD AND INTO A PARKING SPOT IN THE PARKING GARAGE AT MICROSOFT'S HEAD QUARTERS (WHERE I WORK). THE VEHICLE STALLED OUT. I WAS ABLE TO RESTART THE VEHICLE AND GET INTO A PARKING SPACE, BUT IT CONTINUE TO RUN ROUGHLY. I NOTICED AN INTENSE SMELL OF GASOLINE AND IMMEDIATELY TURNED OFF THE ENGINE. I EXITED THE VEHICLE AND CHECKED THE EXHAUST. IT WAS BLOWING WHITE SMOKE AND HAD GASOLINE DRIPPING OUT OF THE TAIL PIPES, I LET THE VEHICLE COOL DOWN AND RESTARTED THE ENGINE WITH ANOTHER PERSON OBSERVING THE TAIL PIPE. IT AGAIN WAS RUNNING VERY ROUGH AND HAD GASOLINE SPRAYING OUT OF THE TAIL PIPE. I IMMEDIATELY TURNED OFF THE ENGINE. THE CAR WAS TOWED TO A SERVICE CENTER. THEY HAVE DIAGNOSED THE ISSUE IS THAT 2 OF THE INJECTORS ARE STUCK IN THE FULLY OPEN POSITION. AS A RESULT, THE CAR IS UNSAFE (I WAS LUCKY THERE WASN'T A MASSIVE FIRE). PREVIOUSLY, I'D HAD THE HPFP (HIGH PRESSURE FUEL PUMP) REPLACED UNDER RECALL. I AM CONCERNED THAT THE RECALLED/REPLACED HPFP MAY ITSELF BE DEFECTIVE AND FAILED, CAUSING 2 INJECTORS TO FAIL SIMULTANEOUSLY (THERE'S STATISTICALLY NO CHANCE OF TWO INJECTORS FAILING SIMULTANEOUSLY WITHOUT SOME CAUSAL FACTOR UPSTREAM IN THE FUEL SYSTEM). ON CONTACTING BMW (IN BELLEVUE WA) AND BMW NORTH AMERICA, THEY HAVE REFUSED TO COVER THE REPAIR OR ACKNOWLEDGE THE ISSUE. I AM CONTINUING TO ENGAGE WITH THEM ON THE REPAIR, BUT BELIEVE THIS IS A MORE SERIOUS SAFETY ISSUE. HAD I NOT PULLED OFF WHEN I DID, THE VEHICLE COULD HAVE WENT UP IN FLAMES WHILE ON THE HIGHWAY.

I'VE HAVE HAD SEVERAL ISSUES INVOLVING THE FUEL PUMP/INJECTORS. ALL SERVICE HAS BEEN PERFORMED AT THE SAME DEALER. THE COST HAS EXCEEDED 3500.00 IN THE LAST 3 YEARS. CAR IS IN THE SHOP AGAIN, DEALER INDICATES FUEL INJECTORS ARE THE PROBLEM, ANOTHER 1989.00 TO GET THE CAR FIX. I BELIEVE THIS IS TOO MUCH $ FOR THE SAME ISSUE FOR A 3 YEAR PERIOD. *TR

I WAS DRIVING AT 60 MILES PER HOUR ON WOODALL ROGERS FWY IN DALLAS, WHEN MY CAR STARTED SHAKING AND WENT INTO LIMP MODE. I PULLED OVER ON THE HIGHWAY AND COULD NOT GET THE CAR TO START AGAIN. I HAD THE CAR TOWED TO BMW. THEY SAID IT HAD NOTHING TO DO WITH A PREVIOUS RECALL ABOUT THE FUEL PUMP AND GAVE ME A $3,000 QUOTE. I HAD IT TOWED TO AN INDEPENDENT SHOP WHERE THEY REPLACED A WATER PUMP AND OTHER ITEMS. HOWEVER, THE RECALL INFORMATION I HAVE BEEN READING DESCRIBES EXACTLY WHAT HAPPENED TO MY CAR. WHENEVER I DRIVE MY CAR NOW AND I ACCELERATE, IT STILL GIVES ME AN ENGINE WARNING AND STARTS SHAKING. I BELIEVE MY CAR IS "SUFFERING" FROM THE WATER PUMP ISSUE.

TL* THE CONTACT OWNS A 2008 BMW 335I. THE CONTACT STATED THAT THERE WAS A PREMATURE LEAK AND STRONG FUMES OF FUEL COMING FROM THE VEHICLE, WHICH PROGRESSED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO A REPAIR SHOP WHERE IT WAS DIAGNOSED THAT THE FUEL PUMP ASSEMBLY NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND PROVIDED NO REMEDY. THE FAILURE MILEAGE WAS NOT AVAILABLE.

2008 BMW 335I COUPE PURCHASED ON JULY 15TH, 2013 FROM CARMAX. CURRENTLY DRIVABLE BUT HAS MAJOR MECHANICAL PROBLEMS. THE EXTENDED SERVICE CONTRACT IS STILL UNDER COVERAGE AND IS VALID AT THE BMW DEALER OR ANY CARMAX NATIONWIDE. WHEN CARMAX CAN'T FIX THE CAR IT'S HAULED OVER TO THE BMW DEALERSHIP TO COMPLETE THE REPAIR AND A CHECK WOULD BE WRITTEN BY MAXCARE TO THE BMW DEALER. THE ONLY PROBLEM IS THAT I'VE HAD TO TAKE THIS VEHICLE IN FOR MAJOR REPAIRS SEVERAL TIMES AND I'M NOT COUNTING MAINTENANCE VISITS. MOST OF THESE MAJOR REPAIRS WERE REPETITIVE MAJOR JOBS SUCH AS OIL LEAKS, FUEL PRESSURE SYSTEM, INJECTORS. AT ONE TIME MY CAR PING PONGED BETWEEN CARMAX AND BMW FOR CLOSE TO 2 MONTHS. CONSIDER THE TIME I'VE OWNED THIS CAR FOR AND HOW LONG AND HOW MANY TIMES IT'S BEEN OUT OF MY POSSESSION. I WAS PAYING A CAR NOTE FOR A BMW BUT DRIVING AROUND IN A A BASE MODEL RENTAL CAR MOST OF THE TIME. I'VE GOT INVOICES/ESTIMATES WHERE THE CAR WENT IN FOR MAJOR REPAIR OR DIAGNOSIS DURING THESE DATES: 07/22/2013 05/30/2014 06/13/2014 07/01/2014 11/05/2014 06/25/2015 THE REPAIR INVOICE/ESTIMATE ON 11/05/2014 WAS THE BIGGEST ONE. I WAS VERY FRUSTRATED WITH THE AMOUNT OF WORK BEING DONE ON THE VEHICLE SO I GOT THE CAR APPRAISED TO SELL BACK TO CARMAX AND THEY TOLD ME $10,000 WHICH I THOUGHT WAS RIDICULOUS. THE WORK DONE ON THAT CAR AMOUNTED TO ALMOST $7,000 OR MORE JUST ON THAT ONE INVOICE WHICH IS 70% OF THE CAR VALUE. ALSO, WHILE THE CAR WAS IN THE SHOP I ACQUIRED THE HISTORY OF THE VEHICLE DIRECTLY FROM BMW. THE HISTORY STATED THAT THE CAR HAD OIL LEAK REPAIR AT THE PAN AND GASKET AND THE AUTOMATIC TRANSMISSION HAD A LEAK IN 03/06/2013 AND THE MILEAGE FOR THIS RECORD WAS COMPLETELY OFF. AS YOU CAN SEE THE DATE OF THIS DIAGNOSIS WAS A FEW MONTHS PRIOR TO ME PURCHASING THE VEHICLE.

EVEN THOUGH THEY KNOW IT'S A 6 CYLINDER I WANTED TO TELL BMW THAT WHEN THEY BUILT THE ENGINE THEY INSTALLED ALL 6 NEW INJECTORS. THEIR REPLY WAS IT ONLY NEEDED 4 AT THAT TIME, WELL WHAT A OUT NOW YOUR TELLING ME I NEED TO REPLACE ALL 6 BECAUSE THEIR OLD INJECTORS SO THE REPLACEMENT DONE WAS TO MASK THE PROBLEM!!! TO THIS DATE THEY HAVE ISSUES WITH THE CURRENT ENGINE PLATE FORM N54 - N55 EPIC FAILURE. SOME SAY ITS ALSO REPLACEMENT OF JUST A FUEL PRESSURE SENSOR. I'M CHANGING MINE ON MONDAY BOUGHT IT ONLINE FROM A BMW DEALER INSTALLATION IS 2-2.5 HOURS BASIC TOOLS NEEDED AND CARE. *TR
