I bet it is... your model can with the torque app read out the dpf temperature.
Or egr shutoff and throtle restriction
Try it
Also if regeneration is going on and your idling the regeneration is halted after a certain time idling activating again after some rpm/load
If there was overfueling at idle there would be higher rpm.... diesel engines
have massive air fuel ratios

When I say its erratic I mean sometimes from one set of traffic lights to another. One set of lights it'll be doing 0.1gph, the next it's 0.3-0.4gph and then back to 0.1gph. When a regen is going on the mpg takes ages to return to 99mpg when I take my foot off the accelerator, whereas when it's not it's shoots up to 99mpg rapidly. There's definitely a fault somewhere other than a simple regeneration. Thanks for the reply 5cylinder. I'm thinking of buying a vida/dice to see if it'll help get to the bottom of this.
