1989 VW Jetta deisel tach.

I have installed a different gauge cluster from another car with a gas motor. The new cluster has a tach the old one didn't. How do I make the tach operate?

You can't, the tach from the gas car reads a signal from the ignition system. Your diesel has no ignition system at all, no can do.

The gauges in the cluster are driven by stepper motors, these are known to fail. There are vendors on E-bay that offer services to replace the stepper motors. This would require you to remove the cluster from the truck.

Gas gauge and tach do not read proper readings! What will cause this? The gas guage will peg past full when there is only quarter tank and tach reads 4500 RPM at idle


The gas tank sounds like a bad ground usually located under the car at the gas tank. I do not know but maybe they both tach and fuel gague get their ground from the same place.

The cluster wont work and it is a new cluster and the fuse is good whats wrong


You don't say why you need to replace the cluster in the first place.

I assume your problem is that the new tacho does not work.

The 89-94 Talons have clusters that look the same. HOWEVER ...

89-91 cluster tachs expect -ive ign pulses, while 92-94 expect +ive pulses (or vice-versa, if forget) . The reason is different ign pulse circuits on the engine.

Hence a 91 cluster tach and the boost gauge won't function in a 93 unless the polarity issue is addressed. It's possible to mix and match parts from your old cluster and the new one. Fiddly but doable.

Electronic immobilizer


most likely cause is the gauge cluster, this will have to be tested and service by your local dealership because the dash cluster and keys have to be coded. I have seen the immobilizer loose it's coding for apearantly no reason. therefore have them recode cluster and see if problem goes away, if it doesn't the gauge cluster will have to be replaced.

replace the cluster which is the whole unit that houses all the gauges on the dash. you can get a used one from a salvage yard cheaper then a new one.

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.

Gauges not working


Ur instrument cluster is most probably the culprit. Smack the dashboard to see if it helps. If it does, bingo, most probably a bad weld on the cluster circuit board. Happens alot on VW's.
