Coding, what not to forget?

[sv1cec]

Gentlemen, please bear with me, I am new to all this. Today, I managed to program my 2005 X5 3.0d to lock its doors when I start driving it (I think it locks the dors above 20km) and I also managed to have it blink twice at me, when I unlock it!!! So pleased with it.

Now, I need to do a couple more things, so any help on this would be greatly appreciated.

1. Locking is fine, but how on earth do I make it to unlock the doors, when I switch off the engine? I assume there is a parameter for that, somewhere, but I haven't a clue what it is. Could someone tell me what that parameter is, and in which module?

2. I would like to have the driver's seat move to its predefined position, depending on the key used to unlock the car. Again, any one knows which module I should edit and which parameter?
