I’ve just completed 430 motorway miles using cruise control. I reset the OBC when I fuelled up and when I arrived the OBC said my fuel consumption was 32.3mpg, however a manual calculation plus the Fuelly App confirms that the fuel consumption was actually 34.2mpg. I was always under the impression the OBC over estimated the fuel consumption.
OBC estimated reading Actual calculated reading

Just back from an 868 mile trip to London and the fuel consumption of the 2.5T was even better on the road home.
The M6 at St Helens was closed between J23 & J26 so had a detour that screwed the test up a little, apart from that it was a steady national speed limit drive all the way and according to the OBC the average speed on the road home was 65mph Before refuelling the OBC display showed I still had 155 miles left after driving 435 miles Once filled it was at 560 miles to empty (I didn't expect that on a 2.5T) At the filling station the OBC displayed 36.2mpg for my 435 miles (apologies for the blurry pic) Calculator out and 54.51 litres of V-Power for 435 miles worked out to 36.4mpg and confirmed with the Fuelly app My average for both journeys worked out to 35.25mpg. Not bad for a 19 years old turbo brick The car ran flawlessly, not a single fault, no more brake pressure DTCs, no squeaks and creaks from the interior and a thoroughly pleasant drive

Good result - about what I get on our 2.5T but the temptation is to speed up to 80mph or so and then consumption takes a hit. Best of all of course are the long stretches of 50mph roadworks and then it gets considerably better.

Just out of interest, how does one reset the computer before a long run or a tank fill to reflect the latest results.

@ lynns hubby
Scroll through the information display until it shows the message you wish to reset then press the reset button on the stalk. Each one needs to be reset separately and you cannot reset miles to empty
