Same problem here, my tach is boucing too. I think you and me need a new cluster mang.
so i have a 98 jetta glx and for some reason the tach stopped working, causing the speedo to not work. everything else works, fuel, temp, miles, clock, ect. ive heard theres something that breaks that can be soldered back on but i have my cluster apart and im not really sure what to look for at this point. any input helps.
When i first bought my car it was doing the same thing. But i pulled the dash one day and found four fuses i believe above the fuse box and pulled them out and cleaned everything up in the dash. And it started working. Maybe theres a loose cable or wire. Its quite irritating though.
my entire cluster quit gas tach speedo temp mileage and time nothing works but when I turn off the key the time and mileage display but not when its on even when they are working they dim out till the car starts I did get a code that the speed censer a has a issue could that cause it to quit this is really getting annoying
I've had the same problem too. Tach bouncing around killin the speedo but the odometer still works. I ended up taking the cluster apart and doing some "tests". I wound up taking a pair of vise grips and put them around the stepper motor for the tach. I then squeezed the motor with moderate pressure without completely breaking it. Ended up working out great for the last 5k miles without a hitch. Not a perfect fix but its nice to have my speedo again until i can get a motor for the tach. seems if either one of the motors cant "seat" themselves on powering the ignition switch they kill the other one. must be a gear starting to let go or something.

SO your saying that the motors will kill eachother? cause last night the tacho blew up and i tried putting it back together and i guess i didnt anyway then the speedometer didnt work either I'm never gonna try and change the color of my cluster again. If i replace the motors though should it work properly?
