Sounds like an electronic speedo problem to me, do the late model cars have electronic speedo? If so it could be your sender or possible a problem with some of the cars wiring, maybe an earth. If it is still cable like the old ones then thats whack, I think they pretty much just work or they dont.

The electronic ones have a sensor in the side of the gearbox instead of a cable and gear so it could be the culprit...NFI how to tell though. :?:

Electrical problems are difficult to diagnose. Mazda factory techs have exceptional docu on chasing down issues like this so why not try a dealer?

IF you are going over 50km/h though.
The ADR's only state that you need an accurate (+ or - 10%) speedo ABOVE 50km/h.
Below that speed, you don't need a speedo, according to ADR's, but try arguing that with a cop in a 40k School Zone. :roll:
