Sorry but them adverts are not fact Craig...there just adverts of people selling a car who really have not read up on what they are selling.
I've also just called a mate down at VW one of the master techs because it is bugging me now and the DPF only came on the Touran, Passat with the 140pd engine.
I also would like to think that Elsawin is right and the guys at VW fixing these things will know what they are working on, not all the time but most of the time
