2014 jetta weather indicator light flashes at 39 degrees

It’s making me crazy how the issues are so diverse, and how it’s been difficult to find a place to start the troubleshooting process. It sounds crazy to me that it wouldn’t even save them, especially with the severity that comes along with some of the issues that the glow plug light could be indicating. When I try to pull up the codes, my reader says that there are none, and there aren’t any saved on the computer either. The car is a 2010, and has about 35000 miles on it. Thanks everyone for all the great info so far. I will have a deeper look at this… i would also advise checking this and i will look at some stuff some more. Its also possible that the engine is opening the waste gate of the turbo, i am almost sure your engine is turbocharged, when that wastegate opens you loose boost, you loose power, your car decelerates in some diesel trucks this is a form of governing! Low fuel pressure will cause drivability issues as fuel pressure is ultra crucial for dieselsįuel injectors not atomizing fuel correctly can cause major issues because if the diesel isn’t atomized correctly it will not burn.Ĭompression for a diesel engine is ultra important because it uses compression too ignite the fuel as it is injected low compression wont inject fuel but this would cause un burnt fuel too come out the tail pipe and cause a miss i am sure in one of the cylinders especially when cold.Įngine reaching operational temp is very crucial for diesel because the air in the combustion chambers need too get hot enough too make the diesel burn, low engine temps can cause drivability concerns. With a diesel engine there is one major difference between a gas engine, it requires compression too ignite the air fuel mixture rather than a spark, fuel is injected into the hot compressed air and burns expanding pressing down the piston.
