For the fuel door to lock, the doublelock feature of your car must be activated. With doublelock the doors,trunk,and fuel door lock. Have the installer insert a 1 amp diode between lock and unlock outputs from the alarm unit. The BMW computer needs a +12v pulse at BOTH lock and unlock inputs to activate the doublelock feature. So that when you arm the unit a +12v lock pulse is sent to both lock/unlock inputs. When you disarm the unit, a +12v unlock pulse is sent only to the unlock input. The diode blocks the +12v unlock pulse to the lock input. I used a 1N4004 diode. Good Luck.

i>: Because I just got my Viper 800esp put in and everything works fine, EXCEPT the guy told me that there is NO WAY that they could get the fuel door actuator to lock! He said he called DEI and CLIFFORD and they both said that it's NOT POSSIBLE! THIS REALLY SUCKS because instead of getting a sense of peace, I am no annoyed that someone can put something into my GAS TANK! (*sigh*) =(
