On my 2006 TDI 140, I am pleased to be able to display the fuel used (kilometers/litre) and of course the averages. However on a recent long trip to the UK from France, the displayed figures were all haywire. The fuel-used display on computer 1, instead of giving a slowly changing number, kept on changing in a very erratic manner. Flicking from 18 k/l to 25, to 85, and then back to something like 22 in succession. It is supposed to take a reading every 30 meters. Previously it has worked very well. I am also suspicious of the numbers shown for average fuel used, which now seems to be far too low. Other displayed numbers such as trip times, fuel range etc, are working OK
Has any member suffered this instability, and does anyone know what would bring this facility back to normal? Does this calculation need an input from a fuel-flow sensor, or is it just a computer calculation? The car has recently been serviced, so I assume it was checked with VAGcom for errors. Everything else on the car is working just fine, just these displayed numbers on the computer (1 and 2) are erratic. Would disconnecting the battery help to reset the onboard computer?
Would very much appreciate any comments/suggestions from members.
