What REAL fuel consumption do people get out of their 2.0 TDis?
I know the headline figure is 50mpg+ and on a motorway run over several hundred miles at 70-80 mph, I can get the trip computer to show an average consumpption of 50-51mpg, but when I actually brim the tank and work out the real consumption accurately, this is only 46mpg in real life - the computer consistently over-reads by 10%.
When people say they get 50mpg, are they really measuring it properly by brimming the tank each time or just quoting what the over-optomistic trip computer tells them?
Overall, I've been driving reasonably sedately including a mix of town use and motorway use and without any real "thrashing". I'm only averaging a real 41mpg over my first 1000 miles of ownership and I'm a bit disappointed with that... (again - calculated accurately by brimming & measuring each tankful rather than relying on the DIS display which I'm finding constantly overreads by about 10%). The car's done 17000 miles, so it should be fully loosened up.
It does seem to dump an awful lot of diesel smoke out of the back when accelerating, but it was only serviced just before I bought it, so there shouldn't be anything wrong with it or they'd have found it then...
What are other 2.0TDI owners getting? - I'm a bit worried that my car may be a bit off.... (but please say whether you're measuring accurately by brimming the tank or just quoting the trip computer...)
