I had the same problem with my 94 jetta, I would also have the alarm turn on as I connected the battery, if you lower the fuse box being careful not to disconnect anything, there is a box to the upper driver-side aria(that is if you are laying on your back looking up under the dash) this is the alarm control unit, there should be a white label on the wires indicating so (think it says alarm in German) theres a 6 pin(wire) connector and a 10 pin. unplug both connectors and look at the 6 pin connector. There is numbers where the wires are located on the connector, if you take a piece of wire and "bridge" wires 5 and 6 (The largest wires on the connector, red/red w/black stripe) your starter should work, any problem with the alarm system can cause the starter to be disabled. after bridging the wires or simply connecting them do not plug anything back into the alarm box, after this you standard vehicle alarm will be disabled permanently, but you will be able to start your car. If this dose not fix the problem you may have a defective starter, hope this helps.

Need to disconnect battery, then remove airbag, the steering wheel (mark before removal), then remove top and bottom sheering column covers, then the spiral spring. At this point you will have access to the housing where the ignition switch is mounted. there is a breakaway bolt that secures this to the steering wheel. Can use an air hammer and gently loosen. Then you disconnect the harnesses from behind. Continue by sliding the housing off and then you will have access to the screw that secures ignition switch in place. Install is the reverse.
