I would just try to fix it. Have you tried leaving it for an hour with the ignition on? Normally it resets itself.

Dont try to bypass the immobilizer, instead of doing that, try this.
Place the key in the ignition and turn it without trying to start the engeene and leave the key therein the ignition like that for a while for about 40 minutes
it will reset the immobilizer to come back to normal even the warning light will desapear.

Using this method to reset the immobilizer is it a permanent fix? my RFID chip is permanently broken ( i drilled through it to make a key ring, didn't know it existed there haha)

Yes, read the writeup in here: http://www.myturbodiesel.com/forum/f21/immobilizer-troubleshooting-how-get-skc-how-disable-immo-3025/ you must know your SKC number. If you don't have it, there's no way to jump it to get to the dealer. I suggest following the troubleshooting steps in the writeup. If none of them work and you don't have the SKC, go to the dealer.
this is insane i have the same problem and mine starts sometime and other times a have the damn light flashing and now im stranded so this better start this time lool

I know this might be late but here is how I did my 02 Jetta TDI. Disconnect battery for 1/2 hour or so. With the doors closed and locked reconnect battery and key in hand unlock, lock and unlock the drivers door several times. Then unlock the trunk several times. Then put in the key and vroom it should work. It did for me and saved me $95 plus the expense of a tow dolly. Hope it works for you
