The ScanGuage II is pretty accurate on my TDI although if I mash the pedal to the floor, it wil go to 9999 for a few seconds and I know that's not right! Arragonis, are you considering E(off) coasting out of curiosity or in the name of science? Our diesels are so much more efficient at idle than a gasser (petrol) that I haven't felt that it was worth it. Depending on my coasting speed (engine on, in neutral) my ScanGuage reads 300-450 miles per gallon Or more! and that's not too bad. I was worried about shutting off the oil supply to a hot turbo, wear and tear from bump starting so often, and on my car, disabled airbags while the key is off. I am sure it can be done safely under the right conditions. I will be following your progress.
