Mein Auto: 740il
Security Code

Hi every one,
This is my first post to the forum but any way I have a 740il and when i put the code into the computer wich is the additional security feature it goes away after I turn the key off and start it up. I notice this when i do it right a way and when i enter the code let it sit for a couple of hours and turn the key no code. Does any one know what is going on with the security system or computer.

frankly, I have no idea what you are asking.

First, what year is your car? That helps us know what security system you are working with.
Second, re-phrase your question so we can understand. You say "...it goes away after I turn the key off and start it up." This doesn't make any sense. When you turn the key off, the engine dies. You have to turn the key (ignition) on before you can start it up. BMW uses key positions. For example, in my 98 750iL, position 0 allows removal of the key from the lock. Position 1 unlocks the steering column and will allow you to turn on the radio. Position 2 turns on all electircal systems. Position 3 is a momemtary position and egnages the starter motor until the engine starts. The engine will not run unless the key is in position 2.

I believe he's referring to the feature where you need to put in the 4 digit code to start the car a la Transporter...
