My 2013 bmw x5 35d was in motion on a city street, when it stalled, lost all power and ultimately would not restart. i was able to get it to the side, but not off the road and it was towed to the bmw dealership where they discovered that there had been a still unidentified sourced, fuel leak into the electrical harness and finally pooling into the dde component, frying the dde component to failure. there was enough fuel in the dde component that it was drained into a drip pan and fuel covered the wiring connection points as well as had discolored the wiring. i was informed that had this been a gas engine and not diesel, it would have probably caught on fire as fuel was able to access and travel across the electrical wiring in the car. bmw has refused to help in anyway to investigating the reasoning for this happening and or any repairs that would be involved as they "do not have a financial responsibility because the car is no longer under warranty" i feel that this is an opportunity for them to discover the reasoning without the destruction of evidence that a fire would have caused and they are choosing not to do so as to claim ignorance to the safety issues that this happening represents.
Tl* the contact owns a 2013 bmw x5. the contact stated that the engine warning indicator illuminated. the vehicle was taken to an independent mechanic and was informed that the fuel tank sensor needed to be replaced. the local dealer was not contacted. the vehicle was not repaired. the manufacturer was not notified. the failure mileage was 72,000. the vin was not available.
Vehicle parked and turned off at my home. many hours later vehicle was discovered by a one of my children on fire . resulting fire destroyed the auto and ignited a major fire to my residence.
No accident, just a safety issue with acceleration delay. total lack of acceleration at a stop to go. there is an inherent lag until the transmission kicks in and goes, about a half second delay. this is obviously not good when trying to get into busy traffic whether at a light or merging. i have talked to bmw tampa and ran a diagnostic without success for a fix. they even admit there is an issue with this but bmw germany guys they say won't change their thinking or fix the issue. in a nutshell it's as if the fuel doesn't get to the injectors until a .05 delay. this is not safe, point blank. *tr
Vehicle developed significantly reduced fuel mileage after the first 500 miles. in town range dropped by 40% to 7.8 mpg over the same route, independent of gasoline source or grade. exhaust gases are very hot and exhibit a pronounced sulfuric, gunpowder like smell. electrical fans constantly on during city driving attempting to cool the engine. excessive carbon build up on exhaust components. engine exhibiting rich running condition. a persistent mechanical engine whine developed emanating from the oil pump, possibly the alternator area of the engine compartment, peaking at 1700-1900 rpm under load. at 1,200 miles, the 8 speed automatic transmission developed erratic shift behavior between 1st-3rd gears. at fairly constant speed, the transmission is shifting between 1st and second gear, alternating up shifting and downshifting without establishing proper gear. coming to a stop, vehicle surges revolutions by up to 500 rpm on the 3-2 downshift and up to 800 rpm on the 2-1 downshift, causing a sudden and abrupt halt, engine braking effect. behavior is most pronounced in standard d transmission mode, minimized in ds mode and completely absent in manual mode with automatic downshift. at 2,200 miles, gunpowder like exhaust gas smell more pronounced and evident while average fuel mileage dropped to 6.4 mpg over the same course. transmission experienced two incidents of failing to up shift into second gear followed by a mechanical clunk and sharp jolt after finally getting in gear. vehicle does not exhibit any stored or active fault codes within the on-board diagnostics. *tr
