Odometer not working

[Jozi]

Picked up a iS this morning, speedo and revs work fine but the odometer never budged on the 200+ mile trip.

I've had a look at the rear of the cluster and it's a proper hack job with ever wire on the white plug having duct tape on them. Before I start re-soldering on a working plug, is my problem related to the wires or is it something mechanical in the clocks?

If speedo works, it's almost certainly a problem with the speedo assembly itself.

Oh yeah speedo works no bother. What exactly should I be looking out for or will it be obvious? Is there something I the wiki for it?

Could be as simple as an obvious cracked solder joint, could be a duff stepper motor, could be the American favourite of gears turned to jelly, or could be damage to the display from the last time the car was clocked.
Apart from the cracked solder, the solution will be the same for the others - fifteen minute job of replacing the speedo unit in the cluster.

Clocked, never

The last add I found for the car it had around 113k miles, 3 years ago. Also found out that at one point or another there was a problem with the clocks and it was sent of to an expert to get fixed. Guess it was never fixed and clocks now show 83k

The above gives me something to start looking for at least!

Anything here that might also be causing problems with the odometer?
