I reckon these are similar figures to the wife's A4 cabriolet, did a couple of long runs in it and saw mid 30's, without the benefit of cruise control and the repeatability that brings.

I'm not complaining of course, I've got my own problems with fuel consumption ;)

Mine gets 45 to 47 on a really long run at 70. 38 to 43 on the motorway, with a bit of a heavy right foot. Around town in the 30's

Mine is a 2011 D4 3.0 for context.

To be honest I rarely look at the mpg screen, no point in getting depressed!

In the time I've had mine from what I've seen my highest has been 36. Couple of long runs coming up next week so will be interested to see what it can do.

You're safer working it out per tank though rather than basing it on the OBC. My first tank averaged 29 and my second 30. I don't even work it out anymore, just enjoy it instead!

Brilliant thanks guys.

In my mind i use the 'mileage gained per tank' mentality to assess realistic fuel usage. Full tank 85-90lts = 570-650 miles usually and I do mostly motorways using regular Shell Diesel.
Just tried Diesel Nitro and it looks like I'm heading for an extra 100-150 miles for the extra £8!

The last two weeks driving equivalent to 624 miles worked out to 33.5 mpg's this is a combination of mixed driving. However I've noticed that the cruise control greatly increases the economy, even trying to manually hold my foot at bang on 70 for the 9 miles of dual carriageway which I often travel on, versus the exact same road set at 70 with the cruise control switched on I'm getting 5 if not more mpg's for doing exactly the same speed.

I'm heading from Cornwall to Birmingham airport this Saturday so will be resetting the trip and hoping for the 40 mpg plus as I also read the various reviews stating low 40's possible out of the 3.0 tdi engine! So in less than three days I'll have the chance of testing it out. +++

Whilst we are on the topic of mpg's out of the 3.0 tdi engine, has anyone here had theirs chipped/remapped and noticed greater economy after or is the marketing or performance upgrades all bull just to sell their products! Only ask as I've been offered an upgrade by three local companies all that I trust after having work off them on previous vehicles that I've owned.

I have noticed exactly opposite various different cars.

It's exactly the opposite.. Mine runs a couple of MPG lower then before. Their claim is usually that you get up to cruising speed quicker, therefore spend longer there and so use less overall..

Here is the latest figures from my 233 bhp 3.0 TDi +++

However I've been contracted next week to move a package to London which 560 miles around trip and as time is not crucial i was thinking of doing some sort of top gear style challenge where I fill the car up and do an Eco Drive, sub 2,000 rpm gear changes, coasting down hill... you know windows up, and squeeze every last mile out of little bit of fuel and really see what I can average over the trip. +++

I seriously believe that the Audi is more economical than my VW CC 2.0 tdi with DSG remapped to 230 bhp! Not by much at the moment but definitely cheaper to run on long distances.
