Hello to everyone, this is my first post and I would like to thank this forum for all the help it has provided me in repairing my diesels of the years. Thank-you
One recent issue I encountered was that of a dead speedometer and tach on my A3 TDI Jetta. I've read of other people with this problem but never found a fix other than replacement of the cluster.
If you have a speedometer that just sits at zero and vibrates and the tach is non-functional then this fix is for you. Note that all my other gauges worked fine.
I went to the local wrecker and obtained another instrument cluster from a 1998/1999 Golf or Jetta ....gas/diesel doesn't matter (cheap $50).Just make sure the speedometer has the same Max speed as your car. The solution after much investigation was to remove the speedometer motor from the donor car. This involves dismantling the cluster, removing the speedometer and tach needles (gently) and de-soldering the 4 conectors that hold the motor to the circuit board. I simply transplanted this motor onto my old board and the cluster is back to life.
This took me about 6 hours to figure out because I tried replacing various components on the cluster until one finally worked. I guess the motor eventually shorts out and cuts of power to the tach circuit.
I certainly hopes this helps other out there. At the end of the day I saved $450 over the cost of a new cluster, and still retained my original odometer reading.
Good Luck!

P.S. Dont forget to check and replace all your light bulbs while you're at it.
