I also have had my TDV6 for about a month but have averaged about 9l/100km (31mpg) combined 115kph highway and around town. On the highway I get about 35mpg at 115kph (73mph) and around town about 28mpg.

It could be just the town driving

My 2.7TDV6 is 2 years old and does around 8.3 lit/100km (34mpg) on the computer but around 31-32mpg if I measure when I fill it up, lots of highway driving at 110kph but also some inner city work. I don't drive very hard but neither do I drive like a pussy.

Have you reset the gauge or done a physical calculation to confirm the mpg?

it does sound low, but setting the cruise robs a couple of mpg, as it is constantly accelerating/breaking - i only use mine on those horrible average speed things!! on a drive up from london this week, i got 34mpg average(doing it the full to full calculation way) which was almost the same as what the computer said. normally with about 70% town driving i get 24mpg (3,0ltr v6) cheers dave MY10 TDV6 SE (debadged ), Santorini Black, Flappy paddles, Privacy Glass, 20" Stormers, Mudflaps!

don't believe what the trip computer tells you. It is very unreliable and not accurate in the slightest. You need to fill the tank set the trip to zero and calculate the actual MPG properly. My car does mainly town driving / stop / start, lights etc. Worst I ever got was the last tank at 16.83 mpg. This was against dreadful weather at -10 and lots of engine running at idle for long periods. I normally get 19mpg. However, if I use it urban and a bit of open road mixed, I get 24mpg consistently. On a run from Glasgow to Manchester and keep below 70mph it will return 30mpg.

Cold weather and town driving are definatley big factors in very poor fuel consumption.

It might be worth getting it remapped with a good mapping company not a plug in and go map, Do you know the history of the vehicle? What mileage has it done has the previous owner ever had it remapped if so it might of been a dodgy one.

Before Christmas my wife who drives our car was getting about 14-15mpg on the 2.7TD. Driving id mostly in traffic never really getting over 30mph. It was definitely worse in the cold weatherthan it had been. I have been getting on mixed driving round about 22-22mpg and on a long run round about 27mpg. Have managed to get about 450 miles out of one tank on a long run. |

Don't look at this pic then!! Done between Carlisle & Cobham on Tesco diesel, no cheating by resettling and coasting downhill. See, D3s save da planet!

That's not good. I would take it to a diesel specialist to seek advice? If you see a bandwagon - it's too late.....
