VDO readings agains GPS
I have recently replaced the stock Transfer Case (1.22 ratio with a 1.410 ratio.)
Now my speedo readings is out by 20 km/h. The "New" case was Cable operated and I have fitted a Speedo Transducer. 0-40 almost equal, 40-80 is 10 km difference, 80-120 is 20 km difference where the speedo shows 120 km/h the GPS shows 100 Km/h. The question is if there is a setting on the VDO ? The truck is a Discovery 1 TDi manuel 1997 mod, 300 000 km. |
You need to change your drive gear.
Speedo cable ratios LT95-LT230-Series TF - Australian Land Rover Owners Or make marks for the right speed on your speedometer. ;) |

Thank you, useful info on recommended forum. I know the current drive gear is green and now I must find out if it will be red or blue. Engine is a 300 TDi, gearbox R380, Transfer LT 230 ,Tyre size 245/70/R16 I could not find the correct combination on the forum.:o |

You might try one of the vendors.

Sorry, didn't notice you were in Mozambique and you might only have dealers as options.

I thought the vdo speedos had a calibration routine.
