A4 B6 speedo not working

[garveypeadar]

Hi
Im new on the site so hi to all. :-)
The gearbox on my A4 B6 sport 02 had to be changed as it wouldn't go into gear. One by one the gears failed. Ok box is now from a 04 model but the speedo will not work. Does anyone have a fix

Hey there,

Is the gearbox the same model code as the one that was taken from the car?

Have you checked your fuses? I know if you take out the ABS fuse on my dads Scenic the speedo stops working! Guess it uses the wheel speed sensor to work out the vehicle speed, don't know if the A4 is the same but may be a quick fix!

Ah i have it working now. the story is the pick up is taken from the ABS on some models but on our one it was from the gearbox. There is a ring on the left hand gearbox output shaft and you can remove or fit it by removing the dif cover and it just clips onto the shaft. The sensor now has something to read off and works as it did.
