2011 BMW X5 SAV Fuelpropulsion System Problems

X5 XDRIVE 35I SAV; WHILE DRIVING UNDER NORMAL STREET AND HIGHWAY CONDITIONS, VEHICLE SPEED AND ENGINE RPM HAVE BECOME UNSTABLE. THIS CAUSES THE VEHICLE TO INCREASE AND DECREASE IT'S SPEED INTERMITTENTLY AND WITHOUT WARNING. THE VEHICLE IS NOT TRUSTWORTHY AS YOU MAY LOSE POWER, OR UNINTENTIONALLY ACCELERATE WHILE TRYING TO EXECUTE A DRIVING MANEUVER, CAUSING A DANGEROUS CONDITION. CHECK ENGINE WARNING LIGHT ILLUMINATES. VEHICLE WAS BROUGHT TO BMW DEALERSHIP (ZT MOTORS) FOR DIAGNOSTICS. SERVICE PERSONNEL STATED THAT THE HIGH PRESSURE FUEL PUMP INDICATED A LOW FUEL PRESSURE AT THE INLET. THIS WOULD TELL ME THAT THE LOW PRESSURE FUEL PUMP IS NOT DELIVERING THE CORRECT FUEL FLOW/PRESSURE TO THE HIGH PRESSURE FUEL PUMP. REF NHTSA CAMPAIGN # 16V746000 ET AL. DIAGNOSTICS ALSO INDICATED THE VALVETRONIC MOTOR SHOWS IT SHORT CIRCUITING. DEALER RECOMMENDED REPLACEMENT OF VALVETRONIC MOTOR, CAM SHAFT AND OIL INJECTORS. THE REPLACEMENT OF THE CAM SHAFT AND OIL INJECTORS...

MY VEHICLE IS HAVING A RECALL REGARDING THE IN-TANK FUEL PUMP SINCE OCTOBER 2016 BMW OF SAN DIEGO HAS FAILED TO PROVIDE A REPLACEMENT PART IN A TIMELY MANNER AND BMW OF EL CAJON HAS JUST PROVIDED THE NECESSARY PART FOR MY PERSONAL VEHICLE I HAVE WAITED ALMOST A YEAR FOR A PART TO BE PROVIDED FOR MY VEHICLE. MOREOVER, THE CAR HAS BEEN EXPERIENCING FAILURES IN IGNITION AND STALLING DUE TO THIS PARTICULAR ISSUE AND POSSIBLY OTHER ISSUES THAT ARE DERIVED FROM THIS SPECIFIC RECALL. OTHER ISSUES REGARDING THE ENGINE COULD BE IN QUESTION DUE TO THE FACT THAT THE ENGINE RARELY SHUTS BY ITSELF WHEN STARTING THE IGNITION, ALSO THERE IS A PROBLEM INVOLVING COLD STARTS IN MOST BMW VEHICLES AND MY CAR IS NOT AN EXCEPTION. THE ENGINE SHUTTING OFF BY ITSELF IS A SPECIAL CONCERN BECAUSE THIS MAY MEAN THERE ARE OTHER FAULTY PARTS LOCATED DEEP...

DRIVE THE VEHICLE ON VACATION AND THE ENGINE WOULD STUDDER AND STALL ON THE HIGHWAY AND AN ERROR PROMPTED ON THE VEHICLE DASHBOARD THAT DISPLAYED "ENGINE MALFUNCTION" REDUCED POWER. OCCASIONALLY THE VEHICLE ENGINE WOULD CUT OFF WHILE ON THE ROAD AND NEEDED TO BE TOWED TO THE DEALERSHIP. THE DEALER DIAGNOSED THAT IT HAS A HIGH PRESSURE FUEL PUMP MALFUNCTION THAT NEEDED TO BE REPLACED AND ALTHOUGH THE VEHICLE IS NOT PART OF THE RECALL IT SHOWED THE SAME SYMPTOMS AS SOME PROBLEMATIC MODELS. THIS OCCURRED WHILE DRIVING THE VEHICLE ON BOTH LOCAL ROADS AND THE HIGHWAY. IN ONE OCCASION, I NEEDED TO RESTART THE CAR TO GET IT TO A SAFE LOCATION.

THE VEHICLE EXPERIENCED A HIGH PRESSURE FUEL PUMP FAILURE. UPON MERGING ON TO A HIGHWAY THE FOLLOWING SYMPTOMS OCCURRED: BACKFIRING, LOSS OF POWER, MISFIRES, AND REDUCED ENGINE PERFORMANCE. THE VEHICLE WAS UNABLE TO MAINTAIN NOMINAL FUEL PRESSURE IN THE FUEL RAIL. THE HIGH PRESSURE FUEL PUMP WAS REPLACED AS PER BMW SERVICE DOCUMENTATION WHICH REQUIRED THE REPLACEMENT OF THE THROTTLE BODY GASKET, AND 2 ALUMINUM BOLTS SECURING WIRING HARNESS TO THE ENGINE BLOCK. THERE WERE NUMEROUS FAULT CODES PRESENT. ALL WERE CONSEQUENTIAL EXCEPT FOR "002C01 HIGH PRESSURE FUEL, PLAUSIBILITY PRESSURE TOO LOW".

THE HIGH PRESSURE FUEL PUMP ALONG WITH HIGH PRESSURE FUEL PUMP SENSOR AND INJECTOR HAS FAILED, CAUSING THE ENGINE TO REDUCE POWER AND MAKING IT AN UNSAFE CONDITION TO DRIVE AT HIGHWAY SPEED.
