My Volkswagen CC has increased fuel consumption since the emissions fix - what do I do?

My 2012 Volkswagen CC diesel is an auto DSG. Fuel consumption has increased by 6mpg since conversion and will not change automatically until the revs are much higher. I told Volkswagen and they weren't interested. They said it had been confirmed performance won't be affected.

This is the standard post NOx emissions 'fix' with the Tiguan 2.0 TDI and now seems to be affecting the CC 2.0 TDI. Because the fault is not resolved you should join one of the class actions against VW UK. I've put links into Good/Bad in the Volkswagen CC entry at www.honestjohn.co.uk/carbycar
