Having problems with your 1994 Volkswagen Jetta ?
Wont start, gives error code IN 02 on dash
\015 Battery is good. When ignition is turned on, the odometer screen in the dash gives the reading IN 02, and when you turn the key to start the car, nothing happens. No clicks. All electronics seem to work fine when the ignition is turned on. \015\012Help?\015
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.
IN 02 is to indicate its time for a service, its set to mileage interval. If you cant start the car you can try disconnecting the battery for an hour or so. If not it might be a simple as a corroded wire.
