:?: The "gain" or sensitivity of the parktronic sensors on my car seem to me to be set too low....what I mean is when backing up to a wall, there is very little change in the number of yellow lights that come on until you are extremely close to the wall, (5 inches) then all the rest (after the 1st three yellow LED's) of the yellow leds and the red ones come on all at once. It seems to me that if they give you so many yellow lights before you get to the red ones, you should have a better idea of how close to the wall you are by the number of yellow LEDs that are currently lit. The red ones should come on when all of the yellows are already lit and you are 10 inches from the wall. Is this "sensitivity" adjustable by dealer service personnel?

my 2004 500 has the same problem, I also have a 2006 LR Range Rover, and the Parktronic sensors alert you even before I am at a reasonable distance...anyone have any additional thoughts on whats causing the delay in the sensors???
