Remember Me? Welcome to the ultimate BMW X3 community. Nonetheless, I'd like to lay out a few points in favor of this feature. I currently have had it turned off for a few days now, and I will probably code it back on after a week or so of experiencing what it's like without it.

Other symptoms may include the car stalling and the check engine light letting up on the dashboard. An automatic shutdown relay, otherwise known as an ASD , is simply a 12 Volt switch that cuts off power to the major systems of a car when you turn off the ignition key. The ASD relay is located in the engine bay, usually near the battery. When you turn off the ignition, the ASD relay disconnects power from the fuel pump, ignition coil, and power control module. This prevents the electrical power from reaching critical engine components in case of a short circuit or wiring defect. It carries several benefits to having an ASD relay in your car:.
