Subsequent Cayenne S and Turbo engines were fitted with upgraded aluminum coolant pipes to rectify this issue. 958 Cayenne models except Hybrid and V6 Diesel suffer with transfer case problems, and Porsche issued a 10-year warranty on 958.1 (2011–2014) and a 7-year warranty on 958.2 (2015–2018), both with unlimited mileage.
Competitors in the Rebelle Rally -- the annual off-road navigational competition for women -- got to play test engineer for eight days, an experience that provided a deep understanding of what ...
A tested Porsche Cayenne, emission standard Euro 6, exceeds the limit by 2.4 times at +10 to +16 °C with an average of 191 mg NO x /km after the software update. In addition, the vehicle with a carbon dioxide emissions of 179 g CO 2 /km is permitted, but in real operation on the road, according to DUH, the emissions are on average 241 g CO 2 /km.
OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
With additional side-mounted coolant radiator and additional electric coolant pump fuel system & engine management (Common rail system) Low-pressure fuel lift pump mounted underneath the car turns on only when starter is being operated (when cranking); after that an electromagnetic valve bypass the pump.
Porsche Cayenne V8 engine. Seven years later, after production ended for the first generation engine, a third Porsche model line with a redesigned eight-cylinder engine caused quite a response. The sports car manufacturer had started on the new Cayenne SUV. The new engine line, with its entirely new design, constituted two engines.
The temperature of the cooling air may range from well below freezing to 50 °C. Further, while engines in long-haul boat or rail service may operate at a steady load, road vehicles often see widely varying and quickly varying load. Thus, the cooling system is designed to vary cooling so the engine is neither too hot nor too cold.
Proper engine coolant and a pressurized coolant system obviate these shortcomings of water. With proper antifreeze, a wide temperature range can be tolerated by the engine coolant, such as −34 °F (−37 °C) to +265 °F (129 °C) for 50% (by volume) propylene glycol diluted with distilled water and a 15 psi pressurized coolant system.
