I have a 98 Jetta wolfsburg. Last night my alarm went off so.I went. Outside and my radio was on and my dash was lit up. I started the car and it wouldn't shut off unless I stalled it out. And the dash lights and radio stay on until I unhooked the battery. I changed the ignition switch this morning and no difference. Any help would be greatly appreciated.
Sticky load reduction relay maybe? Don't think that would keep the fuel pump relay energized though.
Time to break out the wiring diagrams and start checking, start with the ignition switch harness. Something's shorted somewhere.

Need any VCDS (VAG-COM) diagnostics or coding in the North NJ area? PM me.
i know in the more simple times, a bad diode in the alternator would feedback the coil and keep the engine running. Obviously this wouldn't keep the dash lights on. You sure there's not a malfunctioning remote-start system installed? those cheap ones always seem to get weird after a few years.
