2004 BMW 325XI Power Train Problems

THE VEHICLE (1.6 TURBO) HAS A HESITANCY TO ENGAGE IN ACCELERATION RELATIVE TO PRESSING THE ACCELERATOR PEDAL. ONCE ENGAGED, IT IMMEDIATELY JUMPS OUT TO A QUICK, JOLTING AND WHAT FEELS LIKE AN UNCONTROLLABLE START. THIS TYPICALLY HAPPENS AT STOP/START INTERSECTIONS WHERE THE CAR COMES TO A FULL AND COMPLETE STOP. YESTERDAY, (07.20.16) THE VEHICLE CHOKED AND SPUTTERED AND ALMOST STALLED ON A SMALL RISE WHEN TRAFFIC STARTED MOVING THROUGH A JUST-TURNED GREEN LIGHT AT A VERY BUSY INTERSECTION DURING RUSH HOUR. THE TACHOMETER WINDS OUT IN A MANNER DISPROPORTIONATE TO THE SPEEDOMETER READING. THIS DOES NOT MIMIC THE EFFECTS OF A TURBO LAG. RATHER, IT FEELS LIKE THE VEHICLE ISN'T GETTING A TIMELY DELIVERY OF GAS TO THE ENGINE FIRING MECHANISMS (WE WOULD LIKEN IT TO A DIRTY FUEL LINE OR A CLOGGED CARBURETOR ON OLDER CARS), OR THE DUAL CLUTCH SYSTEM IS DEBATING WHETHER OR NOT TO GET IN...

A YEAR AGO, I BROUGHT MY 2004 BMW 325 XI IN FOR ROUTINE MAINTENANCE. WHEN I PICKED THE CAR UP, THE BMW SHOP EXPLAINED THAT THEY FOUND PREMATURE FAILURE OF THE CV OUTER AXLE BOOTS. BOTH BOOTS WERE SPLIT AND LEAKING GREASE, AND THE AXLES WERE TURNING DRY.. THEY REPLACED BOTH BOOTS UNDER WARRANTY. IN DECEMBER 2010, CAR WAS VIBRATING WHILE RIDING. THEY STATED THEY HAD TO REPLACE THE RIGHT FRONT CV SHAFT (AXLE). THEY DID THIS AND THE VIBRATION STOPPED. NATURALLY, THIS WAS NOT COVERED SINCE MY CERTIFIED CAR WARRANTY EXPIRED IN JULY 2010. I BELIEVE BMW SHOULD HAVE DISCOVERED THE DEFECT TO THE AXLE WHEN THEY FOUND IT RUNNING DRY IN JANUARY. IN DRIVING THE CAR BEFORE THE REPAIR, I BELIEVE BMW PUT ME IN JEOPARDY BY NOT REPAIRING THE AXLE. THIS COULD DEFINITELY BE A HAZARD, RIDING ON A SHAKY DEFECTIVE AXLE. *TR
