I have a galxay 1.9tdi 2001 with 118000 miles the car has devoloped a fault which i'm sure most have seen but i can't find anyone that has found the cure.
here goes: The speedo has stopped working and when you start driving the fuel gauage goes up and down.
things that i have done are: replaced the speedo with a 03 model which works fine but runs MPH to fast, so i bought another second hand one which came off another 2001 model and have the problem, so i'm gussesing that my clocks are fine. i have checked the wiring that goes in to the clocks and they are all free from corresion, also done a wiggle test on them.
As the 03 clocks work i know its not a fault with the speedo sensor or fuel sensor as work fine with those clocks it just reads wrong MPH e.g when i do 70 it shows 110mph
Has anyone else had this problem or know how to fix, driving me up the wall now
Many thanks in advance
