  • Plus between 2006 and 2016 didn’t the tax bands change and/or wasn’t there a change in the way they were tested?

    Everything from 1/3/2001 to 31/3/2017 uses the same banding system. I'm guessing the clue is in the "VW" part, they are the main people who cheat emissions tests optimise their engine mapping for the test cycle
