To be honest for me that is normal in the Alps. And yes - I let the horses run - sometimes :cool:

I've been to Tirol (touring on a BMW K100RS bike - nice roads!) and I can tell you it's nothing like Australia. Even what we call mountains are just small hills compared to what you have there. My 2005 3.0d averages 8.6 litres/100km (calculated, not OBC) but most of my driving is rural, not urban.

I'm with Fraser on this one 12.2 L/100km is not good for a 3.0D. My urban commute average is 10.7, and like Fraser 8 to 9 when I go on long trips. 12.7 is petrol V8 territory!

I use to average 16.5/100km in my 2001 4.0L v8. I know the claimed consumption is around to 10-11l/100km mark, but I have never been able to average less than 12 in the daily city running. When doing long trips I have managed as much as 1000km per tank.

I have switched off the auxilary heater and see how I go with the consumption. I think I will have the unit unplugged as long as it doesn't throw any error codes.

My fuel consumption (2005 3.0d) improved quite a lot when I got my air filter replaced. It went from, I think, around 14 down to about 10.

What milage when you replaced the air filter? Had you done much driving on dirt roads?

I had that done last June, a couple of months after I bought it. It hadn't been done for about 60k and was pretty black, unsurprisingly. The previous owner lived on the outskirts of Melbourne, so I guess it's probably seen more than it's fair share of dust.

i just now filled my 05 3.0d up and i did just on 900 km, the add fuel light had just come on, cost $128 aud to fill at $1.489 per litre

i typical drive fastish but not aggressively, mostly bumper to bumper and city driving

i lose about .4 of a litre per 100 km when using the A/C

Which works out about 9.5 litres/100km. That's why I think the OP's mid 12s seems high, even for stop-start city driving.

i agree, i work on 9.4 with A/C and in the winter i got 9 exactly

i log my usage for tax reasons and i,m very consistent with those figures
