Hi T14086, can you tell us anymore about the update, so we can see if it may help the rest of us? Do you know when it was issued, and perhaps from which date 'new' cars would have been supplied with it already installed? Many thanks.
if a ecu flash update is available for the 120bhp with dpf it would appear that there may have been an issue resulting in poor mpg as i am amazed there should be such a difference compared to the 105bhp.
Why don't one of you 120 guys get your doblo remapped complete new fuel map etc would prove if the original is at fault. could pay for its self in no time if raises mpg to the quoted 46mpg combined figure
Worth a thought
