K11 Speedo Issue

[Mistikal]

Hi guys,

Recently purchased a pre-facelift K11 Super S with the CG13DE and factory ABS & disc brake rear.

The car has an issue where the speedo will 50% of the time display just over double the real vehicle speed. It will only correct itself when the car is stationary. It happens at random; sometimes it can go all day working fine and show the correct readout, other times it will show the wrong readout all day, other times it will jump between readouts from traffic light stop to traffic light stop.

Any ideas what it may be? As it is a Super S, it is also the tacho dash, and is only in km/h (as I am actually in Australia).

Any help is much appreciated. Thanks.

Welcome Someone will know the answer and come along soon. Thats a mechanical drive isnt it?

one of mine did the same a few years ago, it was a bit of grit in between the magnetic speedo head drive iirc

Ah excellent, will rip the cluster out and have a tinker later today. Got a can of compressed air here that should do the trick.

Just don't break the cluster. I hear those rev counter ones are like gold dust where you are. They're hard enough to find here lol.
