Do the rest of the clocks work ok? Is it just he speedo?

 

From memory, the speedo works on a square wave signal whose frequency represents the vehicle speed.

 

Start with the vehicle speed sensor (identified as G22 on wiring diagrams) on the gearbox

- pin 3 should be ground

- pin 1 should be 12v with ignition on

- pin 2 is speed signal which goes to dash through the fusebox (G1/11 on Mk3/Corrado CE2)

 

If the wiring seems ok, can you remove the sensor from the gearbox and manually activate it?

(is the sensor working, just not driven by the gearbox?) I've not actually seen the sensor, so winging this bit...

 

 

Good luck!
