I am only averaging 27mpg mostly driving in stop start traffic, Done only 300 miles though. Same journey on my Mercedes (petrol) averaged 19mpg, A6 averaged about 30mpg. My dealer tells me I should get 40 after 1k mikes or so...
Took it for a drive on motorway and averaged 45mpg.
Noticed the service required number has dropped by 3k miles. Is this due to lots of stop start? I do switch off some times.
