i thought that in newer vehicles the fuel was cut off when in gear and off the throttle and uses the momentum of the car to keep the engine turning over and as soon as fuel is supplied the power instantly comes back. maybe that technology is only in the newer models? if your car was at idle in your drive way it would burn fuel still, no? that has to happen for the engine to stay on.
No MAP sensor on the 1.8t. Just a Charge Pressure Sensor on the SMIC (the wrong side of the throttle body to be able to take readings of manifold vacuum).The mpg calculator is a function of manifold vacuum.
No, the gasoline does not act as a lubricant. Piston rings can scuff from lack of lube if overly wet with fuel. Some types of engines use a primer pump to start, for instance light aircraft, and can be damaged from excessive liquid fuel in the cylinders (but that's not a typical Passat issue).How is the engine supposed to stop using fuel unless it's off and not spinning? The fuel acts as a lubricant in the upper cylinder, so you don't want it to run too long without fuel. Which should obviously make people think about my transmission part issue....:hijacked:
