Re: Mpg a7 –

Hi,
I have now had my A7 3.0 TDI 245 for about 3 weeks and have now filled it with diesel for the second time. The first couple of weeks, all I did were mostly local trips where the engine did not really fully warm up, plus a couple of 20 mile runs on the motorway. Over 330 miles, I averaged about 30mpg which is not particularly great, but it was mostly short runs. The car does seem to take quite a while to get any reading on the temperature gauge. My drive to work is only about 2 miles (approx 4 mins) and there is no reading on the temperature gauge when I arrive, whereas my old BMW was fairly well warmed up by then. I guess that this is a much larger and heavier diesel engine and so takes longer. I would be interested in comments from other A7 owners about how long their cars take to warm up.
Yesterday, I took the car (and wife) out for the day to the coast. I filled the tank before leaving and again on return and did a total of about 220 miles, almost entirely on the motorway with the cruise engaged at a steady 75. The computer said that I was getting 39mpg on the way down (50mph head wind all the way) and 44 on the way back. The actual figure worked out from the actual amount of fuel used from full tank to full tank was 38.5 mpg overall for the trip.
This is a lot less than I was expecting from the book figures. Has anyone tried to check fuel figures using the other driving modes such as Eco?? Does it make any difference??
Regards,
Mike
