HI its about the best combo I have used there is another but at about £60 for the kit I fear the Bentley owners can have my share apart from which the Bentley leather is dyed hide where as ours is spray painted.

As Steve has pointed out i think you'll need to clear the old fault codes. Make a note of them though. The do another scan.
Has it done it since?
I mean it could be an egr, dpf or turbo issue.
