Two problems related to manifold/header/muffler/tail pipe have been reported for the 2011 BMW X5. The most recently reported issues are listed below.
Tl the contact owns a 2011 BMW X5. While driving approximately 35 mph and attempted to accelerate, "engine malfunction reduce power" appeared on the instrument panel and the vehicle lost acceleration. The contact drove into a parking lot and turned off the vehicle. The vehicle failed to restart and white smoke emerged from the tail pipes. The vehicle finally restarted and was driven home. The vehicle was towed to BMW of temple (6006 s general drive, temple, TX 76502), but was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 113,900.
The vehicle cut power output from the engine and when restarted would shut off. The dealership declared that the car had incurred water intrusion into the engine compartment without being flooded or submerged in water causing total engine damage that is the equivalent of salvage. The diagnosis as a result of this water intrusion effects diagnosis and recommended fix : diagnostic - check engine light: vtc eccentric shaft, valvetronic servomotor, oil spray nozzle, 6 injectors, and all associated gaskets and hardware. Technician note: diagnosed check engine light, caused by valvetronic servomotor faults, found needing replacement of vtc eccentric shaft, valvetronic servomotor, oil spray nozzle, and 6 injectors. Labor time includes time for programming and diag. (note: one time faults for fuel pressure plausibility, may be consequential of valvetronic malfunction or secondary issue. ) [other]: cylinder head, with replacement gasket, intake and exhaust manifold gaskets, 3 center bolts, and all associated hardware. With new partition, valvetronic servomotor, six injectors, and all hardware for engine removal. Technician note: during injector inspection found injectors 5-6 couplers corroded into head. New injectors will not seat properly and replacement head is required. Note: new head comes with eccentric shaft and rollers. This inflicts financial damage to the consumers since the cost of remedying this is more than the value of the car.
