Failed MAF (mass airflow) sensor? Does the car feel sluggish? If you drove it "REALLY carefully", then you probably didn't even notice. :)

Also, what maintenance has been performed prior to you taking delivery? Have things like air filter and fuel filter been replaced?

Pete

On the few occasions I have had to put my foot down to overtake it didn't appear to be sluggish.

It's due its 80k service so filters haven't been replaced yet. Is replacing these likely double my mpg though? The reason I bought a diesel was fuel economy. I was expecting 40 - 45 mpg not the 20 or even less that I am getting. Its got a months warranty from the garage but they're being less and less helpful and I'm not expecting them to do anything about it. If it does land on me to fix it I'm just wondering what kind of expense I could be looking at. :(

Where on earth did you ever get this crazy idea you could get 40-45 mpg with your Audi?!?! The brand is A U D I, not H O N D A or T O Y O T A . Better yet, get one of these:

Err... have you actually seen a diesel-engined Audi, let alone driven one?

It's a 1.9 *diesel*. 40 - 45 is the expected mpg for the car. There's something wrong with it somewhere.

Wow, 40 - 45 mpg in the A6? That's pretty good - and that's on Imperial gallons, whch are slightly smaller than US gallons.... Man, I wish we could buy those in the US.

The OP is in the UK. 40 mpg (UK) is equivalent to about 33 mpg (US). This kind of mileage should be easily attained by the 1.9 diesel engine. Comparing it to your 2.8 V6 gasoline engine is like comparing apples to oranges.

FYI. I have Volvo 850TDI, wit an audi 2.5TDI engine (103KW). Avg. yearly consumption of only 6.47 litres/100 kms.

Very happy with that :-)

BTW, - I got this

Well, replacing the filters may help some, but it's definitely not going to double your mileage. Good place to start would be to hook up the car to a computer (a VAG tool or similar) and pull the error codes stored in there - this may give you an indication of what is going on.

If you have DIS you should see up to 50 mpg, I have driven the boss's old

They are both "round" though :)

DIS?

DIS - Driver information System

Shows your MPG etc

Ahhh. I see. Unfortunately I don't have it. I just have the basic DIS which shows what needs to be changed and when.

Nope. Imperial gallons are 20% bigger than US gallons.

My A3 TDi 110 *never* does less than 45-47 mpg, even driven quite hard.

Try asking the question at

Does it smoke much? Could it be a leak?
