anyway, did 33 miles to work this morning, gauge didnt move, obc said 50.3mpg. On the way home its dropped to the first mark. Does this sound about right? I've done around 66 miles, obc is saying 50.4mpg and range 605 miles.
Its a CDTi 135 with remap and Synergy 2. Synergy 2 is set to off unless needed (has the switch).
