Hi guys, i post this on w164 too but always, i installed lowering links a few years ago and it was fine and dandy then i noticed it was getting rusty and corroded. I live in the northeast and i drive it in the winter, go figured. So i go and replace my summer tires for the winter tires at my friend shop and low and behold, the arm of the rear height sensor broke off. The link rusted and seized up. it gave no play at all and snapped the arm of the control sensor *both sensor*. anyways i found the part number A0105427717. Every search i did online for this part number bring up a headlamp level sensor. Is that right? Will i need to calibrate the sensor if i buy the "headlamp height sensor"? they both look identical. and I'm going back to stock links on the rear. The lowering links did not lower the rears at all, so whats the point.

1. Do i need to calibrate the sensor?
2. Is the rear ride height control sensor same as headlamp heigh control sensor? *they look identical*

thank you
