When I replaced my Driver Side level sensor on my 2007 E63 recently, it was impossible for me to dial in the proper ride height due to my NOT positioning the sensor appropriately the first time after my haphazardly breaking it upon removal when installing F1 Adjustable Upper Control Arms. By my NOT positioning it such that the top of it was sloping downwards towards me enough, the voltage readings read below 1.8V any time I tried to increase the ride height above 25 1/4 inch measured from floor to fender, which for me was too low. I gained 11mm according to STAR/Xentry after adjusting the sensor by loosening the two mounting nuts and using a screwdriver to isolate the positioning of the sensor to remain sloping downwards as I tightened the nuts because the sensor will tend to twist upwards on Driver Side when tightening the nuts.

FYI, I used the Inclinometer App on my iPhone and layed on my back with one hand under each wheel contacting the nubs on the front Spring Control Arm and the surface of the rear axle. I found it easier starting from the rear and inflating the rears beforehand. Then with my finger on the F3 button to "Release Pressure" with Laptop on my stomach I found it easier to determine that the TOP Height range for the rear is -0.9 degrees while the Bottom of the range is -1.5. Measurement was 26 5/8 or so at -0.9 and about 26 for -1.5 in the rear, not very much room to play with there and even less room on the front. At 3.1 degrees being the Higher in Height than the alternative boundary of 4.1 degrees at the front, I was able to set the front at about 25 3/4 inch at 3.1 degrees while registering 1.8V "heighest height within the 1.8-2.8V range" reading for the front Driver Side after adjusting the sensor position. When I Engage the manually adjusted Height Increase Via the push button, ride height increases to just over 26 inch on front and 27 on rear!!

Now I'm finally able to enjoy the proper dampening of the suspension as I was a bit annoyed beforehand with the effects of the riding position I was forced to maintain due to STAR/Xentry simply NOT accepting my programmed levels if they didn't fall within the specific Voltage ranges, which they didn't when attempting to set at higher height with that Driver front sensor being installed improperly! The driver front range was for me the starting gauge since that level jumps out of range (i.e.- past 1.8 going lower to 1.7x the higher you go) if I inflated higher than 25 3/4 inch. Interestingly, while the range for the driver front was at its edge at 1.8v at 25 3/4, the range for front Passenger was in the middle of its range at that height?? Maybe there might be more room to adjust that Driver front sensor after all, but right now I'm pleased with results!!
