This could be a long complicated post, but stick with it.
To make things easier I'll number things up.It's a 1.8 ts 156
1, original instruments with iffy multi function display.
2, set of orange on black dials
3, orange speedo and centre cluster
4, multi function display.
these are things I bought other than 1 which came in the car.
First I replaced speedo and tacho with dials from 2, found out centre cluster fuel read full, so replaced with original speedo after swapping faces over and centre dials back to normal.
Later replaced centre dials with 2 and MFD with 4. At this point fuel gauge stopped working and MFD telling me engine temp was at maximum and to stop driving,this was after it had been stood all night and not run,whilst temp gauge reached normal when driven!
So I then swapped speedo for 3 and centre dials stopped working, so put original back.
Thene swapped centre dials for 3 and MFD now NOT telling me it is at max temp, fuel gauge now reading something, BUT temp gauge has stopped working !!!
The MFD no matter what combination used still says I'm using 51.2 mpg avg and constant whilst doing zero miles per hour !
Anybody any ideas whats going on ????
Also, if neccessary ,can the MFD screen be swapped over as the original sometimes worked with missing pixels, and that might be the problem.
ps, the dials I bought were from a 1.8 as well.
