Diesel MPG ratings?
 

The diesel engine MPG rating on the Beetle goings down from year to year. I think the 2000s had the best rating. 2005s are rated at much less. Does anyone know why?

This doesn't really answer your question but I did notice that the rating listed in the brocure is a heck of lot higher than the sticker on the '06. The brocure has it listed at 58mpg highway and the sticker was 42 I think. Not sure why the difference.

because the companey lead you to beleave that the 2000 was going to get 58 mpg it gets 46 with me the real deal is it was just a lie the engine is the same

I have a 1998 VW Beetle with the 1.9L TDI engine code ALH. I've got two motors one I've got 66.67 mpg(summer trip few stops avg speed 122 km\hr). The other motor is a 2001 1.9L TDI (ALH). So far the best I've got same kind of drive is 54 mpg. Now both of these motors were moving the same vehicle. WHY such a difference in mpg's. First the 66mpg motor was well boke in, and I had the injection pump timing tweaked. The 54 mpg motor is almost broke in, but the injection pump timing is as was from factory. I believe that this timing is critical to mpg's. DO NOT TRY AND ADJUST THIS IF YOU ARE NOT PREPARED TO SPEND $$$ (Interference engine).
It requires special tools, knowledge, a service manual, and MANY new bolts, Oh yeah lot's of time.

In 2005 they changed to the PD (Pumpe Duse) motor. It has a seperate cam-driven high-pressure injector pump on each cylinder. It has a camshaft driven tandem fuel pump (low pressure) that feeds the higher unit-injector pumps located in the cylinder head under the rocker cover. The 2005 and later 1.9L diesels are rated at 100hp and 177 ft/lbs of torque. It takes more fuel to make more horsepower.
