With LR2 we always see on display average speed, which absolutely doesn't reflect true speed and also it is always lower than we drive. We even though that probably it is in miles and not in kilometers. Our service manager claims that it is calculated as average for the month. Can Land rover engineers implement such rudicilous calculation and to have nobody concerned? No any indication in the manuals or specifications. We drove mltiple europeian cars, which have same functionality and ave. speed displays true ave. speed, correlated every several seconds, which is helpful and gives some indication, when you drive long distance. I called to North America customer service and they have know idea of what should be displayed - busy to find out the answer. Where can we find someone, who knows to give us reasonable answers on LR2?

 

it should do an average of each time you clear the odometer and/or on board computer

 

Thank you! We have checked it this morning and that is exactly the way it works. It starnge that Land Rover customer service doesn't know that. User Manual also doesn't have any details and they should, probably...

 

here is an answer from the NA Land rover exeprts:
Average Fuel Consumption:
The instrument cluster receives 2 fuel tank level readings on the medium speed. The instrument cluster calculates an average value of the amount of usable fuel from the two signals. Every 200 meters of vehicle travel the instrument cluster re-calculates this value to determine how much fuel has been used. The value is then averaged over the last 31 miles (50 kilometers) of travel and displayed in the trip computer.

but generally speaking - trip computer reset fixes the problem

 

I doubt that the courses your service personnel took on the car said anything at all about the display, except perhaps how to fix it. ALL averages will reset everytime you clear the display. MPG, trip, etc., all start at zero. If you don't clear it, then all of your slow, city driving is going to bring the average down.

 

that is exactly what happens. I was surprised that dealership can not explain it to the customers...

 

Sometimes it isn't that they can't explain it so much as they don't understand the question. :-) Sometimes, when my dealer doesn't explain something fully, I reword the question, or take the service manager out to the car and SHOW him what I mean. That usually does it!

 

will do that
