2005 BMW M3 Engine Problems

MY VEHICLE HAS 87,000 MILES AND I WAS JUST INFORMED THAT THE VANOS HAD FAILED. THIS IS THE SECOND TIME THIS ISSUE HAS OCCURRED WITH THIS CAR, HOWEVER THE VEHICLE IS NOW OUT OF WARRANTY AND THEY WANT TO CHARGE ME ALMOST $5,000 TO FIX. I'VE BEEN THE ONLY OWNER FOR THIS VEHICLE AND NEVER HAD ACCIDENTS OR MODIFICATIONS TO THE CAR, IT'S IN ORIGINAL STATE. I SPOKE TO MY SERVICE ADVISER TO SEE WHAT THEY CAN DO, HOWEVER IT'S BEEN ALMOST A MONTH AND WON'T EVEN RETURN MY CALLS. I'VE CALLED THEM AT LEAST 20 TIMES DURING THE PAST MONTH, IT'S RIDICULOUS FOR SUCH A REPUTABLE COMPANY LIKE BMW TO NOT TAKE RESPONSIBILITY OF A KNOWN ISSUE, WHICH I'VE READ ON SEVERAL BMW FORUMS, AND NOW THEY CAN'T EVEN RETURN MY CALLS. IT'S DISAPPOINTING. I GUESS THIS IS MY LAST BMW. *TT

THERE ARE NO VISUAL SIGNS OF THIS FAILURE UNLESS THE VALVE COVER TO THE ENGINE IS REMOVED. UPON REMOVAL THERE IS A METAL FRAGMENT THAT IS RUNNING LOOSE UNDERNEATH THE VALVE COVER. WHEN THIS METAL PIECE FALLS OUT IT CAN ENTER THE TIMING CHAIN AND CAUSE THE ENGINE TO SEIZE AND THE VEHICLE TO HAVE CATASTROPHIC ENGINE DAMAGE. THIS PART BREAKS OFF DUE TO A FAULTY DESIGN OF THE ADJUSTABLE TIMING MECHANISM (VANOS). A REDESIGN OF THE SYSTEM OR REMOVAL AND REPLACEMENT OF PARTS IS NEEDED TO SOLVE THE ISSUE FROM HAPPENING AGAIN. AS A TEMPORARY SOLUTION I HAVE REPLACED THE $1000 DOLLAR PART WHICH HAS THE POSSIBILITY OF FAILING AGAIN. PLEASE ADDRESS THIS ISSUE AS IT IS A WIDESPREAD ISSUE ON THE S54 ENGINE ON THOUSANDS OF HIGH END BMW'S AND LEADS TO A RIDICULOUS FEE TO FIX THAT CAN RANGE FROM $1000-$8000 DEPENDING ON SEVERITY. *TR

THE VANOS SYSTEM IN THE 2001-2006 BMW M3 IS A COMMON PART THAT IS PRONE TO FAILURE. THE INTAKE AND EXHAUST BOLTS OF THE CAM GEAR CAN SHEER OFF DUE TO IMPROPER TORQUING FROM THE FACTORY AND IMPROPER HARDNESS OF THE BOLTS. THE DRIVE SHAFT OF THE VANOS SYSTEM IS ALSO WEAK. IF THE VANOS SYSTEM FAILS, THE CAM GEAR CAN SHEER OFF, AND PARTS CAN GET INTO THE ENGINE AND CAUSE A CATASTROPHIC FAILURE. SOMETIMES, PARTS CAN BREAK OFF INTO THE HOOD OF THE CAR. THIS SYSTEM FAILS WITHOUT RHYME OR REASON, SEEMINGLY AT RANDOM. MANY OWNERS HAVE HAD PROBLEMS WITH THE VANOS SYSTEM.

SOMETIMES REPLACING THE BOLTS ON THE INTAKE AND EXHAUST CAMSHAFT WITH HARDENED BOLTS WILL SOMETIMES FIX THE ISSUE, BUT OTHER TIMES, THE PROBLEM SEEMS RANDOM. *TR
