Brand New A6 3.0TDI MPG trouble
Discussion
I had one for a week recently, well an A5 3.0tdi, and it returned 32mpg over the week and 500 miles. I was pretty amazed as my 3.2 petrol A6 avant returns around 31mpg doing the same journeys.
What was even more amazing was the diesel was returning less than my petrol on sub 10 mile journeys from cold.
They do get better though, mate has one and he averaged under 30 for the first 10k miles, by 30k miles he was showing 33mpg and now at 90k miles he is at 36mpg.

I picked up a 55 plate A6 3.0 TDI Quattro w/ 95 kmiles a couple of weeks back and driving back from Leicester to Aberdeenshire recorded 37 mpg. Driving was a combo of 50 mph Average speed zones and 85 mph yomps in between.
I comfortably got from Leicester to my home in Aberdeenshire without stopping!
Consumption on the B roads where I've been enjoying the torquey engine is much less, around 25 mpg.

big diesels, esp highly tuned tend to afford quite a huge difference in economy between town and motorway driving. They can achieve pretty good figures on a run if the setup has a tall top gear. Not sure if the A5 3.0TDi has or not. My previous E280CDi used to return low 20s MPG normally but on the M-way sat in 7th gear the range would keep going up indefinitely. On a particularly long run I saw nearly 50MPG average, but this is not exactly easy to achieve. Probably a diesel that does 0-60 in under 6s doesn't really beg to be driven with an easy right foot.
Car going into Audi tomorrow, think I've sussed it, the auto box is holding onto the revs for too long, if I drive it on the paddles the fuel econ goes up considerably. I know this is going to sound abit anal but in tiptronic mode it changes gear at 1,600 rpm, and in auto mode 1,900-2,000 which means the fuel difference is amazing. I'm been told it's a software upgrade, strange on a 10 reg car! Anyone want to do the same comparision, I'd be interested to see if its a one off or not.

Is the autobox not a relatively new addition to the A5 3.0TDi? Also, perhaps it learns your driving style which involves sufficient lead foot for it to expect you to drive like that all the time, even if you don't?My 58 plate A6 3.0TDI Tiptronic returns 25mpg around town, 30-35mpg on combined town/a-roads and around 40-42 on the motorway. Its been like that since I bought it, no change in 16,000 miles.
I find my new commute which is far less a-roads and more city traffic really kills the MPG. Now does 25mpg on the way to work, and used to do about 30-35.
I'm assuming you haven't got it continually in S mode on the auto box
