The ScanGauge II has these two choices for Diesel. This has nothing to do with the actual type of fuel but rather the way sensor information is reported by the ECM. Which setting are you finding is the correct one for the '08 3L CRD engine? This can be determined with a little experimentation on the SG but I wanted to see if everyone with this engine came up with the same result.

Thanks,
Wayne

The ScanGauge manual gives a "how to determine which is correct" procedure:
With ENGINE SIZE set, DIESELa chosen for fuel, the engine
warmed up to operating temperature and idling in neutral or park, select
GAUGE and make one of the gauges show RPM and another show GPH.
Note the GPH value. Next, use the throttle to raise the engine RPM to
about 1500 RPM. If the GPH reading increased, you have a DIESELa
vehicle. If the GPH dropped or stayed the same, you have a DIESELb
vehicle and should change the Fuel Type to DIESELb

For my 2005 T1N, i use Dieselb

Dick,
I saw the instructions in my manual too. I was just looking for verification from someone else with the OM642 engine that everyone came up with the same choice.
Thanks,
Wayne
