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.
You can alter the readout from miles pro gallon to for example gallon/distance
Gives much more accurate readouts ...... with no regeneration and depressing pedal ther is fuel cutoff without regeneration WITH regeneration with pedal depressing there will be fuel usage

Even better with torque you can easily alarm and see when a regeneration takes place on your phone in the backround.

If there are no obvious obd2 codes (with torque) then further investigation with vida is needed if its not regenerating
