Thank you for the reply, I've ordered a prox sensor and hopefully will get to install it this weekend, I'm basically going to try to adjust it to compensate with the short falling of the ultrasonic sensors, I've tested those and they only activate the alarm if I actually put my hand on the sensors, not good at all. If I do install this do you know if it will affect my BMW comprehensive extended warranty?

Also, as you know the alarm beep is so quiet, have people just added a louder 2nd siren or is there more to this than I'm thinking?

Thanks again for your help
