That would be the D4 saying “Please replace my rear brake pads”

I’ll get to it some time this week (it’s been on 4 weeks and 3,000km)

Yep, that's with gpsodometer and the servo docket,(the car is actually showing 11.6 atm), our odometer is reading 3.5% slow however it's just occurred to me that my wife usually fuels the car and I probably brim it, she doesn't..... I'll do it again later this week,

So would a general figure of about 2L/100km be around the mark for a roof rack with a couple swags?

Yes I have recalibrated it and it’s correct..



That’s laden, bar, winch, under armour, full Aux tank, wheel carrier, roof rails, awning and Recovery racks.

I've wanted to recalibrate our Speedo and odometer,I can't find a way to do this on a 3 with a nanocom editing the ccf, is it possible?

I also believe and have had it verified that an sdv6 with 8 speed is a MUCH more economical and powerful thing, especially with a remap, are others seeing this, particularly those that have gone from 3 to 4 ?

Your odometer factory should have been almost spit on perfect.. every one I’ve ever checked is, which makes you now out by 4.7% no 3.5. Don’t trust a GPS EVER... for distance.. and for speed it’s only valid in a very straight line!

Yes, I’d believe 2 swags and a rack could easily eat the fuel....

Tyre pressures and type also impact, as does gear choice. I can reduce consumption by taking control from the vehicle with regard to gears. I use cruise significantly except in tight winding roads.

Yes they are...

Mines a 2.7 6 speed though albeit with a nice exhaust and tune.

So without gps, how do you check an odometer?
Because of our conditions, our tyre choice probably can't change,

What difference did the exhaust make? Ours is stock, but I believe has a bas remap but I cannot be sure, is there anyway I can verify who did it?

Also on the gearing, do you think the auto changes too early, too late or too often?

Cheers James

You can use the GPS to check speed. But need a long straight road, corners can fault the data.

The auto is pretty good, in sport more than enough but it works hard once it finds a hill. Preemptive changes help Keep it on the torque band.
