Driving to work this morning, my speedo was sticking at a lower speed. When I was doing 60 it was only displaying 40 odd, speed up to 75 and it was sitting on 50. After about 5 minutes it seems to freed up. Also on the way home it worked fine.

Has this happened to anyone before??

the transducer in the box could be stuffed or the motor thing behind the cluster,,it all elctronic except for a few little gears,,rip it out , clean relube and see what happens
