   recently bought a saxo vtr, the speedo is reading far lower than it should, when it feels like im doing 70 it is reading about 35,
   
   seems to read about half of what the actual speed is
   
   does anybody know where it picks the speed signal up from? it had had a bump at the drivers fron strut and was wondering if this could be related,

   surely a wire would either work.. or not? why would it only read half?
   
   easy enough job, any guides?

   Not got a sat nav or a phone with satnav to check your speed with, so you can see if your speedo's actually out.

   go on the motorway, keep up with traffic and see if it is that far out. If it is, try replacing the speed sensor in the gearbox, a wire should lead to a little sensor stuck in the side of the gearbox. Look im scrappys, its unlikely you'll pick up a dodgy one as they rarely go wrong. If that fails, try replacing the dial. Or the other way round, dial first.

    just noticed today that when driving with the lights on, the backlights on the dials are very dim, also noticed that it wont let me change the time on the dash,
    
    the speedo needle has begun to fluctuate, sometimes rising close to actual speed and then dropping again,
    
    any ideas?
