I have been having intermittent problems with my speedo that now seems permanent. After starting the engine the speedo goes right round to 160 but then drops back to any speed 30, 40, 50 60 etc. So according to the speedo i am doing 120 mph but actually only doing 60...
i found this page and i tried the method, but it doesn't worked for me, my problem is that i don't have the whole car, only the instrument cluster, so i think i need other can bus messages too, can somebody send me a can bus (GMLAN) log/dump file while driving the car? Thank you.
