Greetings from Columbia, SC. I have a 2006 Jetta TDI and I am receiving the blinking key on the dash panel that leads me to believe my vehicle immobilizer system has failed. I have both original factory keys and neither will start the car for more than one second before the cars cuts off. I recently replaced the original equipment battery with an interstate battery. This was over a month ago and I have had no problems until today. Is there some way to reset this myself or get it to over-ride so that I could get it to a dealership? I have tried removing both cables and connecting them for 10 minutes as someone stated in another post and I have tried to leave the key in the ignition for 10 minutes with the ignition on.
