I guys My speedo sometimes doesn't work and I was wondering could it be the sensor of the gearbox or would there be a fuse or something similar I could check had a quick look but I'm stuck any help wold be great full the car is a 98 Terzo edition cheers again

 

It is a problem which seems to affect the v4 impreza and was down to the soldering on the clocks being poor but it could also be the sender unit,try giving the top of the dash a gentle bump while driving if safe to do so.
