2003 A6 3.0 Avant Quattro - Great car but...
I have now bought a 2003 3.0 petrol Quattro. 1 owner from new, 58k miles! Having had 15 plus BMWs, I have to say the ride in this car is sublime! So smooth and light on the steering. Huge load space. What a wagon! But, I'm getting 15mpg around town. I know I should expect poor mpg, I've had a petrol X5 before and still own a 540i (V8) so I'm no stranger to filling cars with petrol. But my V8 gets 20mpg around town. Anyway, is 15 around town normal? looking at the figures I was hoping for at least 19-20 as I'm doing 40-50 on dual carriage ways a bit as well (London). I wonder if there is something wrong with it. I am thinking about a remap, that should improve it a bit.
Any input very welcome!

Great thanks for that! I was thinking around 20 should be right. I'll get it checked out. Any thoughts on a remap? I know the gains are not huge on non turbo cars, but I guess every little helps.

Should probably get better numbers than that but I wouldn't expect a massive increase. Mine was a '04 A6 sedan Quattro with a 4.2L V-8. I normally got around 18 in city numbers and 23-25 on the open highway. GEt the scan down to see what it tells you. Also I would go ahead and check the spark plugs to see how they look. Good quality plugs can be had for $6-$8 dollars US. A couple of years ago when I change my plugs I gained 1.5 to 2 mpg and the engine got a little more peppy right away. It had not been running poorly at the time but I checked the plugs out of curiosity and they showed wear indicating they were due. Also it was such an affordable maintenance job I figured "What could it hurt?" Worth having a look.

My 2.7 gets around 18 city and up to 27 highway. As others have mentioned check codes and vacuum leaks. I would also check O2 sensors and temp sensor since these will both have a real impact on fuel consumption.
Personally I would skip the remap. The car delivered a reasonable combination of performance and economy from the factory so I would try to get back to that point first.
