Guages do not work all fueses are good speedo and tach do not work also

If you have an after-market radio, suspect the CHASSIS GROUND CONNECTION for the instrument cluster.
Also, check all fuses to be sure it isn't a blown fuse.

Sounds like you need a new car.
With joking aside, the problem with your speedo, tach, gas guage, temp gauge and odometer can probably be one of two things. Check your fuses. If they are fine you may need to replace your cluster panel. I had to have the entire thing changed over my speedo not working right. It was not cheap. You might want to check the relay box under the hood. Does your transmission leak? Check the fuses and relay on it also. Get a new ignition switch and replace the old one if your key is stuck. You can try WD40 on that key but don't expect any miracles. The bearings are likely shot. Sorry I posted all of this bad news. Good luck.

Have you checked to see if the instrument panel has a good ground connection? Rust is NOT your friend when it comes to electrical connections!

the case you have disconnect on the ground ( brawon coler) inthe claster . all guage have one ground check the braown coler wire but don't remove or disconnect the calster it may lose key prog try disconnect battarry then check from guage bording up to dash bord bracket . try make sure you have no short with any sender ( fuel .tem. or speedo)

there are buttons are not working, the first one which is responsible to operate the four lights togather ( flasher lights ) . the second buttong is responsible to lock the doors . boh of these buttons are located beside the gear stick.

You have to remove the under hood fuse / relay box and disassemble , check for broken / corroded wires in the harness plugs at the bottom and broken solder joints at the board. I have repaired many of these for the same problem. hope this helps

maybe the speedo drive has stripped some teeth. good luck!

That Cluster will work But, You will have to get an Installation kit if you want the Tach to work. Everything else will hook up the Same. You have a Distribution Box (Fuse Box) Under the Hood on the Drivers Side, There is a Fuse in it for the Speedo. Inside the Cover to the Box is the Fuse Diagram or in the Back of the Owners Manual.

common problem with speed sensor failure

Sounds like a problem in the cluster. These years of VW the clusters could be repared but by someone who knows what they are doing seeing it's printed boards.
