I was told that my car will not work if I do this. How the heck would you replace your battery then? Is there any truth to this?What will happen if you disconnect your battery of a 99 Jetta?...you'll lose all your setttings, including the auto-up/down, which you'll need to reset.
Also, may need to do a throttle body adaptation so the car runs properly.What will happen if you disconnect your battery of a 99 Jetta?obviously your car wouldn't work while disconnected, but its perfectly fine to disconnect and reconnect or change out the battery.
