Thread: Strange fault D4

But it is still just a calculation. Which is really the only point I was trying to make.

I would argue it is an approximation on a calculation!

In a D4,correct.

Many other vehicles seem to be able to have accurate calculations.

You have to remember that even if you don't have the same tyres on the car that came with it, as in, wheel size, tyre size, tyre width and profile, the car will think it is travelling a longer or further distance depending in the tyres. This would easily throw out your fuel consumption calculations.

Correct,but in my situation it was way out with the OEM 18's,and the 17's i run are almost the same diameter as the 18's(within a couple of %).

Larger tyres make the car go further than it thinks so in that respect should help correct the calculation. However with original tyres the calculation is overly optomistic and as LR provided an adjustment factor field in the CCF, they should have settled on a more accurate factor. Instead LR marketing prefers to mislead the driver, that is until the driver does their own calculation.

Well that's probably true as well.

Cruise control is rubbish as well, taking ages to set at the speed you set it at, sometimes dropping 5ks before it engages, even more if we are towing, and it overuns about 2 or 3ks as well, LRs lame excuse was it makes it smoother when engaging.

Where as our daughters Amarok is instant, set it for 100ks and it engages instantly at 100ks, because it does it instantly, there's no slowing then speeding up, which is smoother and no overun like with the D4.

It has it's quirks but I still love driving it, I just wish LRA and some dealers wouldn't treat you like your stupid.

Baz.
