Who is getting what for fuel mileage?? I'm up here in Ontario Canada and am getting terrible mileage now after a software update that caused them to replace my catalytic convertors after (2 month wait) . VW says it's my driving and or colder weather. We bought this back in May and was averaging 550km 12.7km per 100km (18.5 mpg) to a tank to 400km 16.6km per 100km (14.1 mpg). Anyone out there can you tell me what your getting??
