About a week ago I stop to get gas in the mk8 G2, once I put the gas in and got ready to start the vehicle, nothing lights went out, no radio, interior lights, no windows and most of all no start. So I instantly thought damn battery died, but yet I have dash warning lights. So my dad who was with me and who's a professional mechanic did some checking. So we see we have battery power and he wired it to crank from under the hood but it wouldn't turn over, so we towed it back to the garage. After a lot of research (thanks to this site) and process of elimination we came down to it being the SCIL. He wired it to start by jumping from the fuse box under the hood but it has no light except brake lights. So I instantly ordered a use one off of ebay for $91 it took a week to come which was today. We installed it and all the lights worked again but came across another issue.... The SCIL won't recognize the key, uh oh. It needs to be flashed. Well after some studying my dad remembered an old trick and it worked so here it go...
Your gonna run your battery down doing this so be ready.
1) Turn the key to the on position (2)
2) The anti theft light will blink for 15 minutes so let it
3) Once it stop blinking you have 40 sec to turn key off then back on again, remember do not
Take out the key
4) The anti theft light is gonna blink for another 15 minutes
5) once light stop blinking turn key off then back on again and repeat the process a third time totalling a 45 minute reset
6) after light stop blinking turn key off then start car and now your key is programmed to the new SCIL.
Reason why it takes three 15 minute steps is because
1) to learn new key
2) is to erase old code
3) is to program new key.
I hope this helps anyone else in this situation and not have to pay dealer program fee.
