I would me most interested in this one.... I am AXX too, on a September 2005, MY06 car.
Had a revo put on the car, decided I didnt like then the dealer (Drivers Glasgow) flashed it back to something. Since then my mpg has tumbled and I would like to get it back to stock. The buttsurfers at local VW refused to flash it unless there was something wrong and wanted a couple of hours labour...(I left it until I could talk more sensibly to someone in the know).
