You have a bad alternator, it was put together wrong... take it back...

SOURCE: 2003 VW Jetta Charging problem
problem is that the voltage regulators on the 1.8t which I am sure is the same on the TDI alternator....is that they may work fine when they are cold....but once they warm up is when they start acting up and causing problems. I assume is has to do with some resistor over heating. This is just a common problem noticed by most people over at VWvortex.com.
So you can take your alternator to get tested but if it is tested cold then well it may appear to be working ok. When in reality it is broken. Trust me...it is a cheap enough part and easy enough to fix to not just try it. Some can even change the regulator without taking the alternator out. If you have small enough hands I can see it being done.

Either you have a broken wire some where from the speed sensor to the cluster or you have connector at fault, the one which hookup the dash cluster to the main wire bundel. Check the connector, maybe a pushed back pin !!
